Full textAbstract:
The decline of public transport in Western Australia is observed in four separate historical studies which narrate the political and administrative history of each major urban transport mode. Perth's suburban railway system is examined as part of the State's widespread rail network, including the extravagantly-equipped short-lived suburban railway in Kalgoorlie. Political interference in early railway operations is studied in detail to determine why Perth's rail-based public transport systems were so poorly developed and then neglected or abandoned for much of the twentieth century. The llnique events in Kalgoorlie at the turn of the century are presented as potent reasons for the early closure of Perth's urban tramway system and the fact that no purpose-built suburban railways were constructed in Perth until 1993. The road funding arrangements of the late nineteenth century are considered next, in order to demonstrate the very early basis for the present lavish non-repayable grants of money for road construction and maintenance by all three layers of government. The development of private and government bus networks is detailed last, with particular attention paid to the failure of private urban bus operators in the 1950s and the subsequent formation of a government owned and operated urban bus monopoly. The capital structure and accounting practices of public transport modes are analysed to provide a critique of popular myths concerning the merits of each. In order to obtain an impression of the changing political view of different transport modes, the attitude of politicians to public transport and the private motor car over the last one hundred and twenty years is captured in summary narrations of some of the more important parliamentary transport debates. Two possible explanations of public transport decline are discussed in conclusion; one relying a neoclassical economic theory of marginal pricing, and the other on an observation on the fate of large capital investments in the modern party-based democratic system of government.

This model considers and includes three important management systems for an efficient collection value chain: quality management, route management, and HR and community management. The proposed model was implemented and validated in the municipality of Lima, Peru, and the results showed that municipal costs were reduced up to 40%, solid waste was reduced in the streets, and routes and processes were updated and improved in addition to an improvement in the participation and environmental education of citizens. Thus, correct management of the proposed model’s three general approaches to a very positive municipal impact at economic and environmental levels, without the investment of excessive amounts of money observed in first-world countries.

Full textAbstract:
[Truncated abstract] Native vegetation (bushland) in urban areas remains in small, isolated patches embedded within a matrix of human-dominated land uses. Bushlands in urban areas have high biodiversity conservation and social values, and there has been a local-level movement towards protecting and managing urban bushlands in Australia. This thesis aims to test principles, theories and concepts relating to the ecology and management of bushland fragments in Australian cities ... A commonly used qualitative scale was compared with an ecologically based, quantitative technique developed in the research. The qualitative scale was found to be a reliable proxy for assessing vegetation condition, while also being more user-friendly for community groups and other bushland managers. The human-caused disturbances and weed cover in urban bushlands indicate a need for management intervention. Local government has an important role in local biodiversity management, yet there has been little research on this topic ... Positive partnerships developed where local governments have taken a ‘contract model’ approach to volunteer coordination, have a number of expectations of volunteer groups, and provide the groups with relatively high level of assistance. Also important is a local government that supports, respects, trusts and communicates with the community group, and recognises volunteers’ skills, knowledge and contributions. With increased resources allocated to local government bushland management and conservation, and coordination with community groups, the full potential of local bushland management would be realised.

Full textAbstract:
Motivated by disquiet that walking, as both a travel mode and as a segment of public transport trips, is not accommodated well in South African cities, this dissertation has two central aims. The first is to understand better the need for travel by non-motorised modes and within local areas. The second is to contribute to the improvement of local area movement network configuration and management practices. The research is primarily exploratory in nature and was conducted within a 'critical social science' paradigm-in which the research process was driven by a series of questions regarding the critical interrogation of these practices. It explores some of the implications for practice of a post-apartheid urban transport policy discourse that prioritises understanding travel need, managing road space, and accommodating public transport users and pedestrians. Reviews of literature, examination of codes of practice, and interviews with practitioners were conducted to trace the origins and nature of practices in the fields of travel analysis and local network planning and to investigate evidence of relationships between local network planning practices and improved local travel conditions. A household travel survey was administered in metropolitan Cape Town to gather data on travel behaviour across various income bands and in different residential locations. The survey employed an innovative activity-based method, with theoretical origins in time geography. With the use of computer-assisted personal interviewing technology, it involved members of 204 households recording their activity schedule over a 24-hour period. The data were analysed using conventional methods of filtered cross-tabulation, as well as time-space instruments. The research found, inter alia, that as a result of being routinely excluded or underestimated in past surveys, the importance of walking has not been fully understood. Walking would appear to be particularly important in satisfying the travel needs of middle-and low-income households, and walking distance findings would appear to refute assumptions regarding the introverted nature of pedestrian trips that underlie conventional local network configuration practices. In the light of these and other findings the dissertation argues for functionally 'fuzzy' local networks within which pedestrians and cyclists are accommodated on 'permeable' networks of footways, pathways, cycleways and shared roadways, while motor cars are accommodated on variously discontinuous roadway networks. The dissertation also argues for the strategic identification of local areas requiring priority attention, and the preparation of integrated local area plans incorporating co-ordinated and proactive pedestrian planning, bicycle planning and traffic calming.

Urban Air Mobility (UAM) is a concept that proposes to provide short-range transportation solutions that enable customers to travel point-to-point more quickly than they can today using cars or public transportation. The concept of Urban Air Mobility is not new, but there has been rapidly increasing interest in providing air transportation services within major metropolitan areas. The combination of increasing congestion and advancements in electric aircraft and automation makes the Urban Air Mobility market more attractive for vehicle manufactures and transportation companies. There are many potential applications for new aircraft. However, these applications cannot be based solely on what is technological feasible, but must consider the market, demand, and customer needs. This thesis investigates these factors in order to identify operational challenges that may develop during the implementation and operation of an Urban Air Mobility system. The study focuses on Dallas-Fort Worth to set the scope to one potential early adoption market. The objective is to understand the Dallas-Fort Worth environment better in two dimensions. The first is resident's current perceptions and values. The second is the operational challenges and constraints associated with operating a UAM system. In order to meet this objective, a survey of community members and potential early adopters is conducted to determine customer's perceptions of a UAM system and identify operational challenges that may develop based on customer needs. Next, a case study is completed using 10 reference missions in the Dallas-Fort Worth metropolitan area. The missions represented potential commuter trips, point-to-point trips like sporting events, and randomly generated missions. Through this case study, nineteen operational challenges are identified that may impact the development, implementation, and operation of an Urban Air Mobility system. After reviewing each reference mission, community acceptance of aircraft noise and take off and landing area availability were identified as the operational constraints likely to cause the greatest challenges for UAM operations in Dallas Fort Worth.

Alazawi, Z. "Transportation evacuation strategies based on vehicular disaster management system in urban network environment Zubaida." Thesis, University of Salford, 2015. http://usir.salford.ac.uk/34481/.
Full textAbstract:
The importance of emergency response systems have grown tremendously in the recent times due to the many manmade and natural disasters in recent years such as September 2001, July 2005 London bombings and the 2011 Japan earthquake and tsunami disaster. Disasters cost huge human, social and financial losses. For example, in Typhoon Haiyan, as of November 2013, the official death toll from Philippines‟s devastating storm has passed 10,000 people. In addition, based on early estimates, the reconstruction costs could come to as much as $20bn (£12.3bn). Conventional methods for disaster management have shown little prospects of realizing the true potential of current and emerging technologies. This PhD research aims to propose and evaluate a disaster management system based on the emerging ICT technologies with a focus on transportation in urban environments. This work is presented on an Intelligent Disaster Management System based on Vehicular Ad hoc Networks (VANETs) and Cloud Computing. Our research objective is to increase the safety and system efficiency, to reduce the accidents, congestion, and manage the emergencies and disasters. The effectiveness of the intelligent system has been demonstrated through modelling the impact of disaster on real city transport environments and compares it with the case where the intelligent proposed system was in place, and ability of generalizing the concept was increased through applying the proposed system on different cities. By applying our system, substantial benefits have been achieved in terms of improved and balanced traffic flow and smooth evacuation rates. Furthermore, a micro-simulation software model has been developed which employs the vehicular disaster management system in order to investigate the transportation evacuation strategies potential in reducing the human and economic losses. The particular contribution of my thesis is in the modelling and simulation of the traffic for disaster and evacuation scenarios. To this end, this project uses a range and mix of modelling and simulation technologies including macroscopic and microscopic simulation models; OmniTRANS and S-Paramics transport planning software. xix During the course of this PhD, disaster scenarios of varying scales involving 2-3 different cities of various sizes and characteristics have been modelled and analysed, thereby presenting a system which deliver advanced services in managing disasters which results in lower losses. Also, the Average Vehicle Occupancy impact on the evacuation process time has been investigated. Literally, it represents the higher number of car occupancy which means less number of trips required to the evacuation process. The results have shown that AVO contributes effectively in evacuation plans that are in place. Additionally, two different evacuation strategies have been applied and evaluated simultaneously and isolated. Subsequently, either continues the processes or perhaps there is a need to change the strategy where applicable and appropriate. In other words, after propagating the evacuation strategy, the traffic situation has been assessed and observed the effectiveness of the disaster management system on the network by comparing the performance of the proposed system against the traditional system. To sum up, the comparison between both scenarios shows the ability to secure more of vehicles, up to double the number, and hence improve the network performance in terms of safety. Moreover, there is an improvement in flow rate of many critical links. Many blocked links are turned into some reds and blues which means an improvement seemed to occur to the whole network.

Full textAbstract:
Physically decentralised water management systems may contribute to improving the sustainability of urban water management. Any shift toward decentralised systems needs to consider not just physical system design but also social values, knowledge frames, and organisations, and their interconnections to the physical technology. Four cases of recent Australian urban water management improvement projects were researched using qualitative methods. Three cases were of decentralised water management innovation. The other was of a centralised system, although decentralised options had been considered. These cases were studied to identify institutional barriers and enablers for the uptake of decentralised systems, and to better understand how emerging environmental engineering knowledge might be applied to overcome an implementation gap for decentralised urban water technologies. Analysis of each case focused on the institutional elements of urban water management, namely: the values, knowledge frames and organisational structures. These elements were identified through in-depth interviews, document review, and an on-line survey. The alignment of these elements was identified as being a significant contributor to the stability of centralised systems, or to change toward decentralised systems. A new organisational home for innovative knowledge was found to be common to each case where decentralised innovation occurred. ??Institutional entrepreneurs??, strong stakeholder engagement, and inter-organisational networks were all found to be linked to the creation of shared meaning and legitimacy for organisational and technological change. Existing planning frameworks focus on expert justification for change rather than institutional support for change. Institutional factors include shared understandings, values and organisational frameworks, and the alignment of each factor. Principles for, and examples of, appropriate organisational design for enabling and managing decentralised technological innovation for urban water management are proposed. This research contributes to the understanding of the institutional basis and dynamics of urban water management, particularly in relation to physical centralisation and decentralisation of urban water management technologies and, to a lesser extent, in relation to user involvement in urban water management. Understanding of factors that contribute to enabling and constraining decentralised technologies is extended to include institutional and organisational factors. New and practical pathways for change for the implementation of decentralised urban water systems are provided.

La réduction des émissions de gaz à effet de serre (GES) est l'un des problèmes d'action collective les plus importants et les plus urgents auxquels l'humanité doit faire face. Répondre à ce défi politique transversal et transnational semble exiger une action à plusieurs échelles de gouvernance : cela va des changements des comportement individuels à des modifications importantes des cadres réglementaires et des processus de décision locaux, nationaux et internationaux. Adoptant une approche interdisciplinaire, ce projet est élaboré à partir des théories de l'action collective, de l’économie institutionnelle, ainsi que de la gouvernance à multiniveaux et les outils d'expertise afin d’analyser ce qui semble être un modèle de gouvernance « polycentrique » capable d'atteindre les objectifs d'atténuation des GES. Ce projet pose plus globalement la question primordiale de savoir quels sont les changements de gouvernance nécessaires pour générer des réductions réelles et définitives des émissions de GES dans le secteur du transport urbain de passagers. L'atténuation des GES dépend non seulement de la capacité des acteurs de se coordonner, mais également des outils d'information nécessaires pour intégrer ces questions dans la prise de décision à plusieurs niveaux de gouvernance et tributaires des différentes priorités politiques hétérogènes. L'analyse et les conclusions résultant de cette recherche apportent un certain nombre de contributions à la fois à la littérature théorique, et à la pratique générale de la politique ainsi qu’au processus décisionnel spécifique à la France dans le domaine du transport, de la planification urbaine et la gouvernance climatiqueThe reduction of GHG emissions is one of the largest and most pressing collective-action problems facing humanity. Addressing this transversal, trans-boundary policy challenge requires action at multiple scales of governance: from behavioral changes by individuals to modifications of local, national and international regulatory frameworks and decision-making processes. Taking an interdisciplinary approach, this project draws on theories on collective action, institutional economics, multilevel governance, and indicators in decision making to analyze what appears to be an increasingly polycentric governance approach to achieving cross-scale action on GHG mitigation. This dissertation addresses the over-arching question of what governance changes are needed to deliver lasting GHG emissions reductions in the urban passenger transport sector in France? Achieving greenhouse gas mitigation is dependent not only on the ability of actors to coordinate action, but also on the information tools needed to integrate these issues into decision-making at multiple levels of government and across policy priorities. Thus, GHG mitigation must be linked as an often-complementary issue with existing policy priorities. The analyses and findings resulting from this dissertation have a number of contributions to make both to the theoretical literature as well as to general policy practice and the specific decision-making process in France in terms of transport, urban planning and climate governance

Urban sustainability and sustainable urban development concepts have been identified as the ultimate goal of many contemporary planning endeavours and have become central concepts on which the urban development policies are formulated. In the confinement of these concepts, land use and transport integration has been highlighted as one of the most important policy objectives considering the interrelationship between them and available intervention means of planning. While its interpretation varies, in Australia, it has been embraced as integration of land use and transport planning/policies and been an integral part of regional and local plans. Accordingly, a number of principles have been defined to guide its implementation, to name a few, planning for compact and connected urban development, encouraging active transport modes, creation of mixed-use activity centres and public transport precincts, provision of high quality public transport services, and enhancing character and amenity of urban areas. However, there is lack of an evaluation framework to measure the extent of achievement of implementation of these principles. In pursuit of filling this gap, this study aims to devise an evaluation framework to measure the performance of urban settings according to the integration principles in South East Queensland, Australia context and to demarcate problematic areas which can be intervened by planning tools...

Full textAbstract:
This study explores how current flood management policy-making has been influenced by a lack of accurate knowledge - and the substantial ambiguities that exist as an integral part of the peri-urbanisation phenomenon in South East Queensland, Australia. The central conclusion of this research is that land use management in a flood prone area is directly impacted by the peri-urban phenomenon with its spectrum of ambiguities. It was also found that an understanding of peri-urban characteristics differs substantially amongst key stakeholders, and, combined with both ambiguity and a context of rapid, often fragmented development, this difference in understanding may influence policy-making in flood prone areas.

Full textAbstract:
Over the last decade, there has been rapid growth in research into the influence of the physical environment on physical activity. Previously, individual and social factors dominated research into the influences of physical activity. This new area of study has been built on the understanding that the physical environment may create an opportunity or a barrier to engagement in physical activity behaviours (Sallis & Owen, 1997). This research develops objectively measured features of the physical environment in order to investigate relationships with walking behaviour. Public health research of this nature is still at a preliminary stage, although research expertise outside of public health including transportation, urban planning and geographic information science has much to contribute to this emerging field. This study investigated walking in the neighbourhood in a sample of adults residing in Perth, Western Australia. Objective measurement of the physical environment using Geographic Information Systems (GIS) was conducted including measurement of street connectivity, residential density, land use mix and retail floor area ratio at three different geographic scales (suburb, census collection district, 15 minute walk from a survey participants home). These measures were then combined into an index known as a walkability index and validated against survey participant reported data on walking within the neighbourhood using binary logistic regression. Among other findings, the evidence presented shows that depending on which geographic scale the physical environment is measured at and what type of walking in the neighbourhood is reported, the strength of relationship varies between an objectively measured walkability index and walking behaviour in the neighbourhood. These findings highlight the need to differentiate between walking for transport and walking for recreation, health and exercise when investigating the relationship between physical activity and the environment. These findings also show the importance of geographic scale of measurement in the relationship between physical activity and the physical environment, and the need for current high quality geographic data in this type of research.

Thesis (PhD)--University of Stellenbosch, 2001.ENGLISH ABSTRACT: Public and private transport system planning and operation have tended to be fragmented functions. In particular, public transport is often planned and operated independently of the "private" transport system. South African government policy now requires that comprehensive, strategic transport plans be prepared by metropolitan transport authorities. These plans are expected to conform to national strategic objectives as well as including local current and longterm objectives. This planning is required in the environment of a multi-modal, multi-operator, public-private partnership scenario that is new for most of the role players. The lack of experience is accompanied by a lack of any existing model for dealing with this scenario. This dissertation describes such a model. The model is based on the principles of strategic logistics management commonly employed in commerce and industry, including service-oriented industries. The modelling process is thus based on achieving a combination of customer service and long-term objectives. The model comprises a number of separate components and steps: • A transport network model (Emme/2). ~ A multi-class, generalised-cost assignment of private and public transport demand onto a network, modified to be modeless to the public transport users, is performed. This assignment allows for the imposition of generalised-cost reflecting urban-planning objectives in addition to more conventional costs such as travel cost. In this assignment, the interaction of public and private transport is accounted for and results in an associated modal choice. ~ A series of single-class generalised-cost assignments is then used to "focus" public transport demand to create corridors of demand adequate to justify public transport routes. This process can be enhanced to develop a design promoting switching from private to public transport. It also allows for multi-period route design. ~ The results of this modelling process are output to a text file and then subject to the processes described below. The results of these processes are then input into the network model where a standard transit assignment is performed and used to modify the proposed lines and update the network design data with respect to boardings and alightings at nodes. This information is used to design fixed infrastructure. • A Microsoft Access database and route extraction program. );> The network model data is drawn into the database where it is subject to a route extraction program that converts the assignment results from the network model into a set of mode specific potential public transport route definitions. These route definitions are based on paths of maximum demand. The extraction process is controlled by parameters specified by the planner, such as minimum route lengths and the demand level for various categories of service. );> After route extraction, vehicle allocation, and transit assignment, the database provides details of the boardings and alightings and number and details of transit lines using each node and link in the network. This data is used to design fixed infrastructure. • A Microsoft Excel spreadsheet vehicle operating cost model. );> For each vehicle type, the operating cost given the anticipated vehicle mileage and operating speed is determined. This is used to guide the choice of vehicles for different routes. • A Lingo goal-programming model. );> The potential routes and the available or potential fleet are subjected to a goalprogramme in which the optimum choice of vehicle allocation is determined. The allocation parameters can be controlled by the planner. These parameters may include costs, energy, fuel consumption, and vehicle and route limitations amongst others. Multiperiod design is included in the modelling process so that the optimum design may be for the operating period, daily, or weekly cycle. The modelling process provides two main outputs: • A set of fully described and costed transit lines ill terms of both routing and vehicle allocation. These transit line definitions can be output to the level of driver instructions if necessary. • Details of the type and location of infrastructure to be provided on the network.
AFRIKAANSE OPSOMMING: Openbare en private vervoerstelsel-beplanning en -bedryf IS geneig om gefragmenteerde funksies te wees. Dit is veral waarneembaar in die openbare vervoerstelsels waarvan die beplanning en bedryf onafhanklik van die "private" vervoerstelsels plaasvind. Die beleid van die Suid-Afrikaanse regering vereis dat omvattende strategiese vervoerplanne deur die metropolitaanse vervoer owerhede voorberei word. Daar word van hierdie planne verwag om aan die nasionale strategiese doelwitte, asook die plaaslike bestaande en langtermyn doelwitte te voldoen. Hierdie beplanning word vereis deur 'n omgewing wat nuut is vir die meeste rolspelers en bestaan uit multi-modale, multi-operateur en openbare-private vennootskap scenario's. Die tekort aan ondervinding gaan gepaard met 'n tekort aan 'n bestaande model wat gebruik kan word om hierdie scenario's te hanteer. So 'n model word deur hierdie verhandeling beskryf. Die model is gebasseer op die beginsels van strategiese logistieke bestuur wat algemeen gebruik word in die handel en industrie, insluitende die diens-georïenteerde industrieë. Die modelleringsproses wil dus 'n kombinasie van diens aan kliënte en langtermyn doelwitte bereik. Die model bestaan uit onderskeie komponente en stappe: • 'n Vervoernetwerkmodel (Emmel2) }i;> 'n Multi-klas, veralgemeende-koste toedeling van private en openbare vervoeraanvraag op 'n netwerk, aangepas om modusloos te wees vir die openbare vervoergebruiker, word uitgevoer.

Full textAbstract:
Whilst transport has repeatedly been identified as an integral component in the tourism system, the relationship between urban public transport networks and visitor behaviour at urban destinations remains largely unexplored. Furthermore, tourist transport is rarely the subject of the same quality benchmarking techniques that are applied to other elements of the tourism product. The thesis reviews the use of service quality and customer satisfaction measures in urban tourism and urban public transport, highlighting dimensions of urban public transport quality which may be of particular relevance to overseas visitors at urban destinations. The results of a survey of overseas visitors to Greater Manchester, employing both quantitative and qualitative data collection techniques, are subsequently presented, identifying factors affecting the use of public transport by overseas visitors to Greater Manchester. Attributes of public transport service quality, revealed by the research to be of importance in measuring overseas visitors’ satisfaction with urban public transport performance in Greater Manchester, are reduced by means of principal components analysis to reveal the underlying dimensions of overseas visitors’ satisfaction with Manchester’s public transport system. An ensuing regression analysis reveals the relationships between the dimensions of public transport performance, overall satisfaction with public transport and satisfaction with Manchester as a visitor destination. Additionally, an importance-performance analysis is employed to uncover the strengths and weaknesses of public transport service in Manchester from an overseas visitor perspective. The implications for destination management are discussed.

[ES] En la actualidad, uno de los principales desafíos a los que se enfrentan las grandes áreas metropolitanas es la congestión provocada por el tráfico, la cual se ha convertido en un problema importante al que se enfrentan las autoridades de cada ciudad. Para abordar este problema es necesario implementar una solución eficiente para controlar el tráfico que genere beneficios para los ciudadanos, como reducir los tiempos de viaje de los vehículos y, en consecuencia, el consumo de combustible, el ruido, y la contaminación ambiental. De hecho, al analizar adecuadamente la demanda de tráfico, es posible predecir las condiciones futuras del tráfico, y utilizar esa información para la optimización de las rutas tomadas por los vehículos. Este enfoque puede ser especialmente efectivo si se aplica en el contexto de los vehículos autónomos, que tienen un comportamiento más predecible, lo cual permite a los administradores de la ciudad mitigar los efectos de la congestión, como es la contaminación, al mejorar el flujo de tráfico de manera totalmente centralizada.
La validación de este enfoque generalmente requiere el uso de simulaciones que deberían ser lo más realistas posible. Sin embargo, lograr altos grados de realismo puede ser complejo cuando los patrones de tráfico reales, definidos a través de una matriz de Origen/Destino (O-D) para los vehículos en una ciudad, son desconocidos, como ocurre la mayoría de las veces. Por lo tanto, la primera contribución de esta tesis es desarrollar una heurística iterativa para mejorar el modelado de la congestión de tráfico; a partir de las mediciones de bucle de inducción reales hechas por el Ayuntamiento de Valencia (España), pudimos generar una matriz O-D para la simulación de tráfico que se asemeja a la distribución de tráfico real.
Si fuera posible caracterizar el estado del tráfico prediciendo las condiciones futuras del tráfico para optimizar la ruta de los vehículos automatizados, y si se pudieran tomar estas medidas para mitigar de manera preventiva los efectos de la congestión con sus problemas relacionados, se podría mejorar el flujo de tráfico en general. Por lo tanto, la segunda contribución de esta tesis es desarrollar una Ecuación de Predicción de Tráfico para caracterizar el comportamiento en las diferentes calles de la ciudad en términos de tiempo de viaje con respecto al volumen de tráfico, y aplicar una regresión logística a esos datos para predecir las condiciones futuras del tráfico.
La tercera y última contribución de esta tesis apunta directamente al nuevo paradigma de gestión de tráfico previsto, tratándose de un servidor de rutas capaz de manejar todo el tráfico en una ciudad, y equilibrar los flujos de tráfico teniendo en cuenta las condiciones de congestión del tráfico presentes y futuras. Por lo tanto, realizamos un estudio de simulación con datos reales de congestión de tráfico en la ciudad de Valencia (España), para demostrar cómo se puede mejorar el flujo de tráfico en un día típico mediante la solución propuesta. Los resultados experimentales muestran que nuestra solución, combinada con una actualización frecuente de las condiciones del tráfico en el servidor de rutas, es capaz de lograr mejoras sustanciales en términos de velocidad promedio y tiempo de trayecto, ambos indicadores de un menor grado de congestión y de una mejor fluidez del tráfico.[CA] En l'actualitat, un dels principals desafiaments als quals s'enfronten les grans àrees metropolitanes és la congestió provocada pel trànsit, que s'ha convertit en un problema important al qual s'enfronten les autoritats de cada ciutat. Per a abordar aquest problema és necessari implementar una solució eficient per a controlar el trànsit que genere beneficis per als ciutadans, com reduir els temps de viatge dels vehicles i, en conseqüència, el consum de combustible, el soroll, i la contaminació ambiental. De fet, en analitzar adequadament la demanda de trànsit, és possible predir les condicions futures del trànsit, i utilitzar aqueixa informació per a l'optimització de les rutes preses pels vehicles. Aquest enfocament pot ser especialment efectiu si s'aplica en el context dels vehicles autònoms, que tenen un comportament més predictible, i això permet als administradors de la ciutat mitigar els efectes de la congestió, com és la contaminació, en millorar el flux de trànsit de manera totalment centralitzada. La validació d'aquest enfocament generalment requereix l'ús de simulacions que haurien de ser el més realistes possible. No obstant això, aconseguir alts graus de realisme pot ser complex quan els patrons de trànsit reals, definits a través d'una matriu d'Origen/Destinació (O-D) per als vehicles en una ciutat, són desconeguts, com ocorre la majoria de les vegades. Per tant, la primera contribució d'aquesta tesi és desenvolupar una heurística iterativa per a millorar el modelatge de la congestió de trànsit; a partir dels mesuraments de bucle d'inducció reals fetes per l'Ajuntament de València (Espanya), vam poder generar una matriu O-D per a la simulació de trànsit que s'assembla a la distribució de trànsit real. Si fóra possible caracteritzar l'estat del trànsit predient les condicions futures del trànsit per a optimitzar la ruta dels vehicles automatitzats, i si es pogueren prendre aquestes mesures per a mitigar de manera preventiva els efectes de la congestió amb els seus problemes relacionats, es podria millorar el flux de trànsit en general. Per tant, la segona contribució d'aquesta tesi és desenvolupar una Equació de Predicció de Trànsit per a caracteritzar el comportament en els diferents carrers de la ciutat en termes de temps de viatge respecte al volum de trànsit, i aplicar una regressió logística a aqueixes dades per a predir les condicions futures del trànsit. La tercera i última contribució d'aquesta tesi apunta directament al nou paradigma de gestió de trànsit previst. Es tracta d'un servidor de rutes capaç de manejar tot el trànsit en una ciutat, i equilibrar els fluxos de trànsit tenint en compte les condicions de congestió del trànsit presents i futures. Per tant, realitzem un estudi de simulació amb dades reals de congestió de trànsit a la ciutat de València (Espanya), per a demostrar com es pot millorar el flux de trànsit en un dia típic mitjançant la solució proposada. Els resultats experimentals mostren que la nostra solució, combinada amb una actualització freqüent de les condicions del trànsit en el servidor de rutes, és capaç d'aconseguir millores substancials en termes de velocitat faig una mitjana i de temps de trajecte, tots dos indicadors d'un grau menor de congestió i d'una fluïdesa millor del trànsit.
[EN] Currently, one of the main challenges that large metropolitan areas have to face is traffic congestion, which has become an important problem faced by city authorities. To address this problem, it becomes necessary to implement an efficient solution to control traffic that generates benefits for citizens, such as reducing vehicle journey times and, consequently, use of fuel, noise and environmental pollution. In fact, by properly analyzing traffic demand, it becomes possible to predict future traffic conditions, and to use that information for the optimization of the routes taken by vehicles. Such an approach becomes especially effective if applied in the context of autonomous vehicles, which have a more predictable behavior, thus enabling city management entities to mitigate the effects of traffic congestion and pollution by improving the traffic flow in a city in a fully centralized manner. Validating this approach typically requires the use of simulations, which should be as realistic as possible. However, achieving high degrees of realism can be complex when the actual traffic patterns, defined through an Origin/Destination (O-D) matrix for the vehicles in a city, are unknown, as occurs most of the times. Thus, the first contribution of this thesis is to develop an iterative heuristic for improving traffic congestion modeling; starting from real induction loop measurements made available by the City Hall of Valencia, Spain, we were able to generate an O-D matrix for traffic simulation that resembles the real traffic distribution. If it were possible to characterize the state of traffic by predicting future traffic conditions for optimizing the route of automated vehicles, and if these measures could be taken to preventively mitigate the effects of congestion with its related problems, the overall traffic flow could be improved. Thereby, the second contribution of this thesis was to develop a Traffic Prediction Equation to characterize the different streets of a city in terms of travel time with respect to the vehicle load, and applying logistic regression to those data to predict future traffic conditions. The third and last contribution of this thesis towards our envisioned traffic management paradigm was a route server capable of handling all the traffic in a city, and balancing traffic flows by accounting for present and future traffic congestion conditions. Thus, we perform a simulation study using real data of traffic congestion in the city of Valencia, Spain, to demonstrate how the traffic flow in a typical day can be improved using our proposed solution. Experimental results show that our proposed solution, combined with frequent updating of traffic conditions on the route server, is able to achieve substantial improvements in terms of average travel speeds and travel times, both indicators of lower degrees of congestion and improved traffic fluidity.

This thesis explores the potentials for using urban growth management tools to improve transportation system performance in a developing country context, focusing specifically on the case of the Santiago de Chile metropolitan area. In industrialized countries, such as the United States, recent years have seen a renewed focus on using urban growth management for achieving mobility goals. This work looks at how such tools might be deployed in a rapidly growing urban environment, characterized by evolving institutional structures, major changes in transportation demand and services, and pressing economic, social, and environmental constraints. The thesis firs begins with an overview of the national political and administrative structure in Chile - the institutional context within which growth management must function. The thesis then presents the Santiago metropolitan area, overviewing demographics, the economy, the transportation system, urban growth patterns, and the environment. Then, the range of current instruments used for growth management in Chile and Santiago are presented, along with other relevant influences such as the public finance system. The following section reviews the real estate market, focusing on the emergence of large developers and their associated "megaprojects," which play a major role in shaping the city's growth patterns and trends. Finally, the thesis concludes with major findings, recommendations for improvements to the current growth management system, and areas for future work.

Full textAbstract:
The financial and environmental effects of traffic congestion and automobile-centric air pollution
continue to be problems that must be addressed within the United States. In response, travel
demand management (TDM) has emerged as a potential way to reduce automobile-based travel
in order to minimize these effects. TDM strategies are highly dependent on specific urban form
characteristics such as bicycle lanes, sidewalks, or transit facilities. A current gap exists in the
analytical tools available to transportation planners when evaluating TDM projects. The standard
transportation models do not take into account urban form characteristics in a systematic way.
These characteristics play an import role in an individualâ s selection of walking, bicycling, or
transit based travel modes. This gap needs to be filled in order to evaluate TDM projects with
the same decision-making rigor that is applied to road expansion projects.
The purpose of this project is to develop an enhanced transportation mode choice model that
presents a systematic approach for incorporating urban form characteristics. This approach
determines which elements of urban form have the strongest influence on transportation mode
choice behavior. This work is being done in conjunction with the Roanoke Valley Allegany
Metropolitan Planning Organization as a way to evaluate the potential of TDM projects in
promoting non-automobile forms of travel within the Roanoke region. This approach to
developing an enhanced transportation mode choice model is a step forward in address the gap
between TDM strategies and the tools needed to evaluate them.Master of Urban and Regional Planning

The purpose of this research is to help increase the capacity of public-sector transportation agencies (such as state Departments of Transportation, Metropolitan Planning Organizations, and transit providers) to preserve and enhance transportation-related quality of life (QOL) outcomes in their jurisdictions. QOL is a multi-dimensional concept that is closely related to the concepts of livability and social sustainability. Public-sector agencies are charged with promoting the well-being (i.e. QOL) of the public, and they often must work within a complex inter-organizational context, with overlapping and intersecting jurisdictions and responsibilities, in order to influence QOL. Because of their responsibility to promote QOL, many public-sector transportation agencies mention QOL, livability, and/or sustainability in their vision statements, mission statements, and strategic planning documents. Furthermore, U.S. Federal guidance and regulations that govern the practice of transportation planning, engineering, and performance management have begun to refer to issues related to livability and sustainability. However, these complex concepts are still ambiguous in meaning and application for many transportation practitioners. In order to effectively preserve and enhance transportation-related QOL outcomes, practitioners need a clear conceptual framework that links concepts of livability and sustainability to practical performance management tools for an inter-jurisdictional context. The primary objective and contributions of this research are the development of such a conceptual framework - the stacked systems framework (SSF) - and a methodology for applying it to enhance transportation performance management in an inter-jurisdictional context. In order to develop the SSF, this research begins with an extensive literature review that clarifies the relationships among sustainability, livability, and transportation-related QOL outcomes; and integrates the concepts of social sustainability, soft systems methodologies, and the field of transportation performance management. To apply the SSF, this research includes a case study of public-sector transportation performance management processes in metropolitan Atlanta. The case study analyzes the influence of the regional inter-organizational system of public-sector transportation agencies on transportation-related QOL outcomes; identifies gaps in the current set of transportation performance measures used for decision making at the regional scale; and demonstrates the value to decision making of incorporating recommended performance measures that can more appropriately link organizational actions to broader QOL and livability outcomes via changes in transportation service quality. The case study methodology can be extended for future development of transportation performance management practices in metro Atlanta, and reproduced for other regions and geographic scales.

Full textAbstract:
The Australian water industry is facing two major challenges: a rise in water demand due to a growing population and a decrease in rainfall availability due to a drying climate. This situation has triggered a re-evaluation of traditional water schemes and promoted consideration of alternatives for sustainable urban water management. One possibility is to replace drinking water usage in garden and outdoor irrigation with non-potable groundwater. This could save almost half of the water supplied in the residential sector, which is the biggest consumer of scheme water in most Australian cities. A major hurdle for the success of such fit-for-purpose groundwater schemes can be the lack of the resident’s participation and support. Currently there are uncertainties about the dynamic nature of individual’s attitudes in terms of satisfaction and accepting behaviours towards the fit-for-purpose water use. This can cause ambiguity in planning and implementation of such projects.
The main purpose of this thesis is to address the following specific research questions: What are the factors that determine residential satisfaction with and behaviours towards the fit-for-purpose groundwater system? and What are the implications of such water system for community, water utilities and urban planners?
These questions have been addressed through a quasi-experimental study utilizing two northern suburbs in Perth metropolitan: Ridgewood and “The Green”. “The Green” is selected as an experimental suburb and Ridgewood is selected as a control suburb, which is a standard metropolitan suburb having the usual main drinking water system. The use of non-drinking groundwater through the dual water supply system in “The Green” began in 2008 alongside the main water scheme. A broad spectrum of parallel literature from many disciplines was drawn upon to inform the research. Concurrent preliminary informal conversations with local residents and a number of field observations were helpful in refining and contextualising the research hypotheses regarding the determinants of residential satisfaction with the fit-for-purpose groundwater supply system in the context of water sensitive urban development.
An exploratory mixed method approach was adopted starting with qualitative preliminary interviews with local residents to inform the development of a survey instrument. This was followed by the administration of the survey questionnaires at household level to collect quantitative data to measure the relationship among variables and test a model of residential satisfaction. The survey data and the secondary data about residential water consumption were analysed to develop a workable model for residential satisfaction with and behaviour towards the dual water supply system and water sensitive urban environment. Finally, qualitative information during stakeholder interviews, meetings, and seminars was used to interpret the planning implications of the model and behavioural responses towards the water system and urban development.
The research results indicated that the majority of residents (70%) are satisfied with the nondrinking groundwater supply system in their home and neighbourhood. In “The Green”, the household drinking water consumption was reduced by 40% compared to the metropolitan average; however, excessive garden watering exemptions for new garden establishment caused 30% more water usage in “The Green” than the metropolitan average. This study found that the major components of residential environment satisfaction were the neighbourhood, neighbours, and home. Home satisfaction in “The Green” was determined mainly by home attributes and the garden satisfaction, which in turn was dependent upon garden attributes and satisfaction with the groundwater system. In this way, groundwater satisfaction had an indirect impact on home satisfaction mediated by garden satisfaction. The major determinants of groundwater satisfaction were: positive perceptions of operational issues, and risk of groundwater use (negative relationship), and preference for continuation of the groundwater system after its trial period.
The major research findings are explained in Chapter Six, Seven, and Eight. The dynamic nature of community attitudes and community behaviours towards the fit-for-purpose water projects at urban settings were explored, and the planning and development consequences of the implementation of the alternative water systems were explained. The results of this study are highly applicable for water providers, urban planners, and community developers in promoting the successful implementation as well as improvement of fit-for-purpose water systems from a policy perspective. This thesis equally contributes to building knowledge and understanding of residential satisfaction and its relationship to innovative dual water systems in water sensitive urban environments. It facilitates the sustainable management and planning of urban water resources. The research also demonstrates the need to integrate general models of community satisfaction with specific water system attitudes to provide an indication of the role of water supply systems in the overall success of water sensitive developments.

Full textAbstract:
Routing and designing are essential for transportation networks. With effective routing and designing policies, transportation networks can work safely and efficiently. There are two transportation problems: hazardous materials (hazmat) transportation and warehouse logistics. This dissertation addresses the routing of networks for both problems. For hazmat transportation, the routing can be regulated via network design. Due to catastrophic consequences of potential accidents in hazmat transportation, a risk-averse approach for routing is necessary. In this dissertation, we consider spectral risk measures, for risk-averse hazmat routing. In addition, we introduce a network design problem to select a set of closed road segments for hazmat traffic with conditional value-at-risk (CVaR) to regulate hazmat routing. In warehouses, the routing of electric forklifts with sufficient battery levels is for material handling. The optimization model of dynamic wireless charging lane location is proposed under the workflow congestion in parallel-aisle warehouses. Considering the uncertainty of demands, the wireless charging lane location problem is formulated as a two-stage stochastic programming model. We confirm the efficiency of the proposed algorithms in solving these problems and the key advantages of use the proposed routing and designing policies via case studies.

Thesis (Ph. D.)--Massachusetts Institute of Technology, Engineering Systems Division, Technology, Management, and Policy Program, 2007.Includes bibliographical references.
Designing a flexible system with real options is a method for managing uncertainty. This research introduces the concept of "complex" real options, which are composed of interconnected echnological, organizational and process components. "Complex" real options differ from the "standard" real options described in the literature in the option life-cycle activities of design, evaluation and management. To address the challenges posed by "complex" real options, the Life-Cycle Flexibility (LCF) Framework was created. The framework addresses issues along the entire life-cycle of an option, in both technical and social system dimensions. Two case studies were considered in this research to better understand "complex" real options and test the LCF Framework: 1) a large blended wing body aircraft in a commercial aircraft manufacturing enterprise and, 2) Intelligent Transportation System (ITS) capabilities in an urban region with multiple public and private stakeholders. For the case studies, both a quantitative and qualitative analysis was completed. System dynamics and traffic demand models were used to quantitatively evaluate flexibility for each case study. Forty interviews with practitioners were conducted to better understand the practical challenges associated with flexible systems.
(cont.) This research found that there are significant differences between "standard" and "complex" real options. In the design phase, enterprise architecture issues must be considered either as a precursor or simultaneously with the design of the option. In the evaluation stage, option valuation techniques more sophisticated than those found in the real options literature were needed to value the "complex" real options. In the management stage, political considerations were of great importance as political opposition could prevent option exercise from occurring. Without the LCF framework, existing processes for evaluating real options are not adequate for taking into account the interacting technical, organizational and process components of 'complex" real options. In summary, this research provides new insights into the design, evaluation and management of "complex" real options.

Full textAbstract:
This research, denoted MILOS (Multi-objective Integrated Large-scale Optimized ramp metering System) is a hierarchical structure for solution of the large-scale freeway management problem to address the key features of this problem (dynamic state changes, stochasticity, multi-dimensionality, unpredictability, partial-observability, and existence of multiple objectives). MILOS decomposes the freeway control problem into subproblems along temporal/spatial boundaries and is composed of three primary components: SPC-based anomaly detection and optimization scheduling, area-wide coordination layer, and predictive-cooperative real-time (PC-RT) optimization layer. The area-wide coordination component of the hierarchical control system considers the impact of queue growth on the adjacent interchanges in a quadratic programming optimization model with a multi-criterion objective function. The formulation of the area-wide optimization problem is augmented with overflow variables to guarantee a feasible solution. The nominal solution of the areawide coordination problem is then modified in real-time by the locally traffic-reactive, PC-RT algorithm based on a linear-program using a linearized dynamic difference equation implementation of the macroscopic FREFLO model. The PC-RT formulation pro-actively plans to utilize opportunities to disperse queues or hold back additional vehicles when freeway and ramp demand conditions are appropriate. The cost coefficients of this optimization problem is linked to the solution of the area-wide coordination problem by using information on the dual of the solution to the area-wide coordination problem. The optimization runs of the area-wide coordination problem and the PC-RT optimization problems at each ramp are scheduled by a demand/flow monitoring system based on statistical process control. A simulation experiment is executed to evaluate the MILOS hierarchical system against "no control", ADOT's current ramp metering policy, and an area-wide LP optimization problem resolved in 5-minute intervals on a small freeway network in the metropolitan Phoenix, AZ area. Three test cases are presented for a short "burst" of heavy-volume flows to all ramps, a 3-hour commuting peak, and a 3-hour commuting peak with a 30-minute incident occurring in the middle of the network. The performance results indicate that MILOS is able to reduce freeway travel time, increase freeway average speed, and improve recovery performance of the system when flow conditions become congested.

Full textAbstract:
This thesis explores how revenue management (RM) principles would integrate into a parking system, and how advanced reservation-making, coupled with dynamic pricing (based on booking limits) could be used to maximize parking revenue. Detailed here is a comprehensive RM strategy for the parking industry, and an integer programming formulation that maximizes parking revenue over a system of garages is presented. Furthermore, an intelligent parking reservation model is developed that uses an artificial neural network procedure for online reservation decision-making.
Next, the work evaluates whether the implementation of a parking RM system in a dense urban parking district (and thus avoiding "trial-and-error" behaviors exhibited by drivers) mitigates urban congestion levels. In order to test this hypothesis, a parallel modeling structure was developed that uses a real-time decision-making model that either accepts or rejects requests for parking via a back-propagation neural network. Coupled with the real-time decision-making model is a micro-simulation model structure used to evaluate the policy's effects on network performance. It is clear from the results that the rate at which parkers renege is a primary determinant of the value of the implementation of RM. All other things being equal, the RM model in which the majority of parkers is directed to their precise parking spot via the most direct route is much more robust to the random elements within the network that can instigate extreme congestion.
The thesis then moves from micro-evaluation to macro-evaluation by measuring the performance of the urban parking system from the perspective of the set of relevant stakeholders using the hyperbolic DEA model within the context of the matrix DEA construct. The stakeholder models, including that of the provider, the user, and the community, have defined inputs/outputs to the hyperbolic DEA model, which allows for the inclusion of undesirable outputs such as network delay and incidence of extreme congestion. Another key contribution of this work is that of identifying design issues for current and future dense urban parking districts. Clearly, reneging rate and the tenacity of perspective parkers is a key consideration in cases where RM policy is not implemented.Ph. D.

Full textAbstract:
Energy and environmental impacts are two factors that will influence urban region composition in the near future. One emerging issue is the effect on water usage resulting from changes in regional or urban transportation trends. With many regions experiencing stresses on water availability, transportation planners and users need to combine information on transportation-related water consumption for any region and assess potential impacts on local water resources from the expansion of alternative transportation modes. This thesis will focus on use-phase water consumption factors for multiple vehicle modes, energy and fuel pathways, roads, and vehicle infrastructure for a given transportation network.
While there are studies examining life cycle impacts for energy generation and vehicle usage, few repeatable models exist for assessing overall water consumption across several transportation modes within urban regions. As such, the question is: is it possible to develop a traceable decision support model that combines and assesses water consumption from transportation modes and related mobility infrastructure for a given mobility network? Based on this, an object-oriented system model of transportation elements was developed using the Systems Modeling Language (SysML) and Model-Based Systems Engineering principles to compare water consumption across vehicle modes for assessing the resiliency of existing infrastructure and water resources.
To demonstrate the intent of this model, daily network usage water consumption will be analyzed for current and alternative network scenarios projected by policies regarding the expansion of alternative energy. The model is expected to show variations in water consumption due to fluctuations in energy pathways, market shares, and driving conditions, from which the model should help determine the feasibility of expanding alterative vehicles and fuels in these networks. While spatially explicit data is limited compared to the national averages that are used as model inputs, the analytical framework within this model closely follows that of existing assessments and the reusable nature of SysML model elements allows for the future expansion of additional transportation modes and infrastructure as well as other environmental analyses.

Full textAbstract:
This research develops a framework to estimate the effective sample size of Global Positioning System (GPS) based panel surveys in urban travel behavior studies for a variety of planning purposes. Recent advances in GPS monitoring technologies have made it possible to implement panel surveys with lengths of weeks, months or even years. The many advantageous features of GPS-based panel surveys make such surveys attractive for travel behavior studies, but the higher cost of such surveys compared to conventional one-day or two-day paper diary surveys requires scrutiny at the sample size planning stage to ensure cost-effectiveness.
The sample size analysis in this dissertation focuses on three major aspects in travel behavior studies: 1) to obtain reliable means for key travel behavior variables, 2) to conduct regression analysis on key travel behavior variables against explanatory variables such as demographic characteristics and seasonal factors, and 3) to examine impacts of a policy measure on travel behavior through before-and-after studies. The sample size analyses in this dissertation are based on the GPS data collected in the multi-year Commute Atlanta study. The sample size analysis with regard to obtaining reliable means for key travel behavior variables utilizes Monte Carlo re-sampling techniques to assess the trend of means against various sample size and survey length combinations. The basis for the framework and methods of sample size estimation related to regression analysis and before-and-after studies are derived from various sample size procedures based on the generalized estimating equation (GEE) method. These sample size procedures have been proposed for longitudinal studies in biomedical research. This dissertation adapts these procedures to the design of panel surveys for urban travel behavior studies with the information made available from the Commute Atlanta study.
The findings from this research indicate that the required sample sizes should be much larger than the sample sizes in existing GPS-based panel surveys. This research recommends a desired range of sample sizes based on the objectives and survey lengths of urban travel behavior studies.

Full textAbstract:
This thesis studies peri-urban landscapes (the landscape between the rural and urban setting), which has until recently gained little attention in academia and even less in planning practice and policy. This is largely due to a general view of these landscapes as something transient that will be developed in the future. However, some research has recognised these landscapes as important for the leisure and recreation of urban and suburban dwellers. Thus, this thesis is concerned with the current state of the peri-urban landscape, its characteristics and drivers of change with a focus on accessibility. Accordingly, the interest of the study lies in exploring people’s landscape perceptions and uses in relation to the accessibility of periurban areas and how they change over time. The focus of this thesis is Ljubljana and Edinburgh; these two cities have been selected as the case studies in order to elucidate the spatial and social patterns of the space on the edge of the city. The thesis centres on the perspective of inner-city dwellers’ perceptions, use of, and accessibility to peri-urban green spaces. Guided by the sense of place theory and the landscape planning approach, empirical work is at the heart of this research. A mixed-method approach, comprising questionnaire and focus groups with inner-city dwellers, interviews with authorities and planners and GIS-based analysis, is applied to gain new knowledge of inner-city dwellers’ relationship with periurban green spaces. The research found that people greatly value the established peri-urban green spaces, which have a variety of meanings for them, varying according to people’s socio-demographic and cultural characteristics. Furthermore, the appreciation of extensive semi-natural green spaces and green corridors has been shown to be universal and may imply some clues for further spatial planning of these areas. Conversely, people in general did not use the areas with low intrinsic value that are perceived as messy, ambiguous, etc. It appears that these spaces have lost their sense of place and therefore they are under threat of further development. Their future should thus be considered within long-term planning goals, in order to ensure environmentally sustainable and socially inclusive development.

Full textAbstract:
Several aspects make today’s transport system non-sustainable: • Production, transport and combustion of fossil fuels lead to global and local environmental problems. • Oil dependency in the transport sector may lead to economical and political instability. • Air pollution, noise, congestion and land-use may jeopardise public health and quality of life, especially in urban areas. In a sustainable urban transport system most trips are made with public transport because high convenience and comfort makes travelling with public transport attractive. In terms of emissions, including noise, the vehicles are environmentally sustainable, locally as well as globally. Vehicles are energy-efficient and the primary energy stems from renewable sources. Costs are reasonable for all involved, from passengers, bus operators and transport authorities to vehicle manufacturers. The system is thus commercially viable on its own merits. This thesis presents the results from three projects involving different concept buses, all with different powertrains. The first two projects included technical evaluations, including tests, of two different fuel cell buses. The third project focussed on development of a series hybrid-bus with internal combustion engine intended for production around 2010. The research on the fuel cell buses included evaluations of the energy efficiency improvement potential using energy mapping and vehicle simulations. Attitudes to hydrogen fuel cell buses among passengers, bus drivers and bus operators were investigated. Safety aspects of hydrogen as a vehicle fuel were analysed and the use of hydrogen compared to electrical energy storage were also investigated. One main conclusion is that a city bus should be considered as one energy system, because auxiliaries contribute largely to the energy use. Focussing only on the powertrain is not sufficient. The importance of mitigating losses far down an energy conversion chain is emphasised. The Scania hybrid fuel cell bus showed the long-term potential of fuel cells, advanced auxiliaries and hybrid-electric powertrains, but technologies applied in that bus are not yet viable in terms of cost or robustness over the service life of a bus. Results from the EU-project CUTE show that hydrogen fuelled fuel cell buses are viable for real-life operation. Successful operation and public acceptance show that focus on robustness and cost in vehicle design were key success factors, despite the resulting poor fuel economy. Hybrid-electric powertrains are feasible in stop-and-go city operation. Fuel consumption can be reduced, comfort improved, noise lowered and the main power source downsized and operated less dynamically. The potential for design improvements due to flexible component packaging is implemented in the Scania hybrid concept bus. This bus and the framework for its hybrid management system are discussed in this thesis. The development of buses for a more sustainable urban transport should be made in small steps to secure technical and economical realism, which both are needed to guarantee commercialisation and volume of production. This is needed for alternative products to have a significant influence. Hybrid buses with internal combustion engines running on renewable fuel is tomorrow’s technology, which paves the way for plug-in hybrid, battery electric and fuel cell hybrid vehicles the day after tomorrow.QC 20100722

Full textAbstract:
During the past several decades, most U.S. metropolitan areas have experienced strong suburbanization of housing and jobs (i.e., urban sprawl). The sprawl that arises from urban growth has become a big issue in many metropolitan areas in the U.S. In response, there has been increased interest in urban containment policies. There are contrasting views (planning-oriented vs. market-oriented) of urban sprawl and urban containment policies. Planning-oriented scholars asserted the problems of `geographic sprawl (GS)' and the positive effects of urban containment polices, while market-oriented scholars asserted the problems of `economic sprawl (ES)' and the negative or negligible effects of urban containment policies. Therefore, this dissertation analyzed whether urban containment policies affect urban sprawl, employment center formation, and urban commuting.
The results of this dissertation indicate that urban containment policies play an important role in affecting urban sprawl, employment center formation, and urban commuting, as well as explaining the contrasting views (planning-oriented vs. market-oriented) of urban containment policies. Implementing urban containment policies can produce positive effects such as compact development, which can promote J-H balance. However, as seen in the relationship between urban containment policies, urban sprawl and housing values, stronger urban containment policies can produce negative effects, such as traffic congestion and an increase in housing prices.

Thesis (MPhil)--Stellenbosch University, 2012.ENGLISH ABSTRACT: Human existence in its current form is unsustainable. Urban transport systems are one of the chief contributors to this problem due to the dominant role of the car. Car dominated transport systems have a number of serious impacts on social, economic and ecological systems which collectively suggest they are not sustainable. The complex, global “system of automobility”, a powerful socio-technical regime, ensures that car dominated transport systems endure, despite the serious problems they generate. In the face of the power and resilience of this system, there are examples around the world of urban areas which have implemented transport initiatives which depart from the dominant paradigm of automobility. They have successfully provided viable alternatives to the car, facilitated urban forms which are supportive of green modes and “reconquered” scarce urban space from the automobile. However, there are a multitude of barriers to any transition to sustainable urban transport systems. These can only be overcome through the related processes of contestation and innovation. The case of Stellenbosch is a local expression of the global “system of automobility”. Through a combination of infrastructure, urban form, institutions, beliefs and ways of life, this system is perpetuated at a local level. In a highly inequitable developing country context, this is particularly problematic. A town primarily designed to service car mobility is best suited to the reproduction of the middle class. The poor, and others without access to a car, are at a disadvantage and movement by green modes is, everywhere, discouraged. And yet, there are a number of innovative initiatives occurring within the town which depart from the dominant paradigm, contesting its continued dominance. The path towards transition is at all times uncertain. However, it is possible to enhance the potential for transition by strengthening existing niches, contesting existing regimes and preparing for the imminent increase in landscape pressure generated by climate change and resource scarcity.
AFRIKAANSE OPSOMMING: Menslike bestaan in sy huidige vorm is onvolhoubaar. Stedelike vervoerstelsels is een van die belangrikste bydraers tot hierdie probleem weens die oorheersende rol van die motor. Vervoerstelsels waar die motor die botoon voer het ‘n aantal ernstige gevolge op maatskaplike, ekonomiese en ekologiese stelsels wat gesamentlik daarop dui dat sodanige stelsels nie volhoubaar is nie. Die komplekse, globale “stelsel van motorvervoer”, ‘n kragtige sosio-tegniese regime, verseker dat vervoerstelsels waar die motor die botoon voer in stand gehou word, ondanks die ernstige probleme wat hulle skep. Met inagneming van die krag en veerkragtigheid van hierdie stelsel bestaan daar oral in die wêreld voorbeelde van stedelike gebiede wat vervoerinisiatiewe geïmplementeer het wat afwyk van die oorheersende paradigma van motorvervoer. Hulle het uitvoerbare alternatiewe vir die motor suksesvol verskaf, stedelike vorme wat groen gebruike ondersteun gefasiliteer en skaars stedelike ruimte van die motorvoertuig “herwin”. Daar is egter ‘n menigte hindernisse in die pad van enige oorgang tot volhoubare stedelike vervoerstelsels. Dit kan slegs oorkom word deur die verwante prosesse van verset en innovering. Die geval van Stellenbosch is ‘n plaaslike uitdrukking van die globale “stelsel van motorvervoer”. Deur ‘n kombinasie van infrastruktuur, stedelike vorm, instellings, gebruike en lewenswyses word hierdie stelsel op ‘n plaaslike vlak bestendig en behou. Teen die agtergrond van ’n uiters onregverdig ontwikkelende land is dit in die besonder problematies. ‘n Dorp wat in die eerste plek uitgelê is om vervoer wat op motors berus, te bedien, is veral geskik vir die reproduksie van die middelklas. Die armes en diegene sonder toegang tot ‘n motor word benadeel en beweging met behulp van groen wyses word oral ontmoedig. En tog kom daar ‘n aantal vernuwende inisiatiewe in die dorp voor wat afwyk van die oorheersende paradigma wat die voortgesette oorheersing daarvan beveg. Die weg na oorgang is te alle tye onseker. Dit is egter moontlik om die potensiaal vir oorgang te verbeter deur versterking van bestaande nisse, bestryding van bestaande regimes en voorbereiding vir die toenemende druk op die landskap weens klimaatsverandering en die skaarste aan hulpbronne.

Full textAbstract:
Automobile use is associated with significant problems such as air pollution and obesity. Decisions to use the automobile or its alternatives, including walk, bicycle, and public transit, are believed to be associated with urban form. However, in contrast to the hypothesis that compact urban form significantly reduces automobile travel, previous studies reported only a modest effect on travel behavior. These studies, largely built on microeconomic utility theory, are not sufficient for assessing the effect of compactness, for several reasons: (1) The studies postulate that travel invokes only disutility, but travel may also provide intrinsic utility or benefits insomuch as people travel for its own sake; (2) the studies have traditionally focused on how urban compactness reduces the distance between trip origin and destination and accordingly reduces trip time, but urban compactness also increases congestion and reduces trip speed, and thus increases trip time; and (3) the studies have mostly examined automobile commuting, but people travel for various purposes, using different travel modes, and the impact of urban compactness on the utility of non-automobile non-commuting travel has not been duly examined.
On this ground, to better explain the effects that urban compactness has on travel behavior, this dissertation refines the concept of travel utility using two additions to the microeconomic utility theory: activity-based utility theory of derived travel demand and approaches to positive utility of travel. Accordingly, it designs a conceptual model that specifies travel utility as an intermediary between urban compactness and travel behavior and examines the behavior associated with and utility derived from travel mode choices for alternative purposes of travel. Twenty individual models are derived from the conceptual model and tested within the context of Seoul, Korea, using a confirmatory approach of structural equation modeling and data from geographic information systems and a structured sample survey, which is initially designed and validated by semi-structured interviews and subsequent statistical tests. By comparing the individual models, this research concludes that the urban compactness effect on travel behavior, represented by trip frequencies and supplemented by mode shares, is better explained when travel utility is considered and if travel purposes are separately examined. Major empirical findings are that urban compactness affects travel behavior mainly by increasing the benefits of travel in comparison to its modest effect on the cost reduction and people’s behavioral response to urban compactness is to shift modes of commuting travel, decrease travel for shopping, and increase travel for leisure. These purpose-specific findings have implications for transportation planners and public health planners by assisting them in linking plans and policies concerning urban compactness to travel purposes.

Full textAbstract:
Urban traffic congestion is recognised as a major problem by most people in world cities. However, the
implementation of congestion reducing measures on a wide scale eludes most world cities suffering from
traffic congestion, as many oppose the notion of road pricing and despite economists and transportation
professionals having advocated its benefits for a number of decades. The effects of road pricing have
attracted considerable attention from researchers examining its effects, as it is thought to hold the key in
understanding and overcoming some inherent obstacles to implementation. Unfortunately, many of the
attempts consider the effects in isolation and with hypothetical, idealised and analytical tools, sometimes
loosing sight of the complexities of the problem.
This research empirically investigates the effects of road pricing in London, and identifies factors, which
may prove to sustain it as a traffic reduction instrument. The results indicate that an integrated approach
has to be developed and implemented, based upon the recognition of local perceptions, concerns,
aspirations and locally acceptable solutions, if the acceptance of road pricing is to be improved. The key
to dealing with the effects of road pricing, is to encourage a concerted effort by various stakeholders
developing strategies considering a range of differing initiatives, coordinating and managing them in the
realm of the political-economic context in which they exist.Thesis (M.Art. et Scien. (Town and Regional Planning))--North-West University, Potchefstroom Campus, 2005.
