The key assumption of public transport is the overall accessibility for all its users. Lack of adjustments or only partial adjustments of the touristic transport infrastructure to the needs of elderly and disabled persons constitutes a barrier for their free mobility. The study aims to formalize measures to improve public transport activities by identifying the problems of the disabled and the elderly while traveling. The article presents an assessment of the current state and recognizing the most important problems of the physically disabled and elderly persons in the mobility in the city using public transport. The research part of the article attempts to assess the availability of solutions in public transport for the physically disabled and elderly persons. For practical simplification, the article focuses on the mass transport implemented by the only possible means of this type of transport for the research is a bus.In line with the predefined criterion, one city from the region of Bielsko-Biała was included into the research – city Szczyrk. In the article, the diagnostic survey was used as the best research method. The basic technique for collecting the empirical data was the open participating observation using the observation sheet. The basic research was complemented by the direct survey of disabled persons with various levels of disabilities to achieve intended results.The research concluded that the mobility of disabled persons in the transport processes was assessed positively despite multiple difficulties and obstacles caused by their limited mobility and the lack of transport infrastructure adjustments (bus stops or information systems).

Sustainable urban mobility remains an emerging research topic during last decades. In recent years, the smart card data collection systems have become widespread and many studies have been focused on usage of anonymized data from these systems for better understanding of mobility patterns of Public Transport (PT) passengers. Data-driven mobility patterns can benefit transport planners at strategic, tactical, and operational levels. A particular point of interest is a spatiotemporal dynamics of mobility patterns that highlights transformation of the PT passenger flows over the time continuously or in response to modifications of the PT system and policies. This study is aimed to estimation and analysis of the spatiotemporal dynamics of PT passenger flows in Riga (Latvia). A multi-stage methodology was proposed and includes three main stages: (1) estimation of individual trip vectors, (2) clustering of trip vectors into spatiotemporal mobility patterns, and (3) further analysis of mobility patterns’ dynamics. The best practice methods are applied at every stage of the proposed methodology: the smart card validation flow is used for extracting information on boarding locations; the trip chain approach is used for estimation of individual trip destinations; vector-based clustering algorithms are utilised for identification of mobility patterns and discovering their dynamics. The resulting methodology provides an advanced tool for observing and managing of PT demand fluctuation on a daily basis. The methodology was applied for mining of a large smart card data set (124 million records) for year 2018. Most important empirical results include obtained daily mobility patterns in Riga, their clusters, and within-cluster dynamics over the year. Obtained daily mobility patterns allows estimation of a city-level PT origin–destination matrix that is useful in many applied areas, e.g., dynamic passenger flow assignment models. Mobility pattern-based clustering of days allows effective comparison and flexible tuning of the PT system for different days of a week, public holidays, extreme weather conditions, and large events. Dynamics of mobility patterns allows estimating the effect of implementing changes (e.g., fare increase or road maintenance) and demand forecasting for user-focused development of PT system.

Sharing mobility solutions changes people’s lives in cities; however, such services are not common in remote areas, where the most widespread transport mode is a privately owned car. The main challenge is that the existing transport system fails to meet the population’s daily travel needs in such regions. Sharing mobility covers environmental issues, infrastructure development, digitalisation, integration of different transport modes, and people behaviour changes. This study analyses the possibility of expanding the existing urban mobility sharing system in remote tourist areas of Lithuania; for this purpose, a small resort in the central part of Lithuania – Birštonas was selected, and a survey of residents and tourists (visitors) was conducted. Using the survey results of residents and tourists, the needs for Car Sharing (CS) and micro-mobility services are determined. The attitude of municipality, residents, tourists, service providers towards micro mobility and vehicle sharing services is determined. Based on the achieved results, further steps of service development are proposed. The article’s main aim is to evaluate the views of various stakeholders on the development of micro mobility and CS systems in remote areas and propose development solutions.

The mobility management concept encompasses various services, organisational and advisory measures that allow users to change their travel choices.The article investigates various aspects and factors of mobility management policy. The transport behavior, the possibilities and expediency of joint trips, cycling and walking, the issues of changing transport behavior and making changes in transport infrastructure were studied. The cost-effective options for improving the road use efficiency, the volume and quality of information given to traffic participants as well as the intensity of its provision, which ensure the success of the mobility management policy, were analysed.The comprehensive policy in the field of bicycle and pedestrian traffic is necessary at the city level or even at the national level linked to the policy of urban development for the successful use of bicycle and pedestrian transport. The mobility management policy directed to encourage the wider use of cycling and pedestrian transport should be aimed to removing barriers obstructing their use. It is also necessary to make changes in existing infrastructure in order to increase the traffic capacity during rush hours.

REFLEXES OF URBAN OCCUPATIONS ON MOBILITY TO THE MARGINS OF THE STATE ROAD GO-060 BETWEEN GOIÂNIA (GO) AND TRINDADE (GO) ABSTRACT The study aims to understand the dynamics of the various types of occupations implanted around the State Highway GO-060, between the city of Goiânia (GO) and Trindade (GO), and their reflexes on urban mobility. The problem is identified in the cause and effect relationship in the conflict between urban space and the transport system in conurbated areas of the Metropolitan Region of Goiânia (GO). The objective is to analyze the areas of occupation of the spatial area, the vehicular flow of the modes of transport and the mobility index, according to the types of occupation, characterized as travel generating poles (TGPs). To identify such occurrences, methodologies adapted for spatiotemporal analysis and networks were used. The results showed the differences in occupation areas in the Trade / Industry Type 25.74% and 30.77% and Residential Type 11.41% and 38.78% for the West / Mendanha and Trindade 2 Regions for the periods (2011/2016) and (2009/2015) respectively. This occupational dynamic generated an increase of + 87% in the total travel flow of the different modes of transport and an increase of + 79% in the mobility index for the period from 2013 to 2016, showing the trend of motorization in the regions and the reflexes in urban mobility. Keywords: Spatial occupation. Road system. Vehicular flow. Transport. Mobility.

La prise en compte des usagers est aujourd'hui incontournable pour les professionnels en charge de la production des services de mobilité. Or, qu'il s'agisse de services traditionnels ou de nouveaux services collaboratifs comme le covoiturage, l'essentiel du travail de ces professionnels se déroule en l'absence des usagers, inaccessibles ou encore inexistants. La prise en compte des usagers se traduit alors par la mise en place d'outils variés (enquête, concertation, traitement des réclamations, communication, système d'information, etc.) destinés à représenter les usagers dans les différentes dimensions de la production du service. Au croisement d'approches interactionniste, sociotechnique et communicationnelle, cette thèse propose une lecture unifiée de ces divers outils de prise en compte des usagers en tant que travail collectif de construction d'une fiction de l'usager. Les professionnels élaborent cette fiction à l'articulation de leur travail d'interaction avec les usagers pendant lequel ils les mettent en scène et de leur travail de réflexivité pendant lequel ils les mettent en récit. Cette recherche repose sur une enquête qualitative menée chez deux producteurs franciliens de services de mobilité, constituée d'observations participantes de situations de travail et d'entretiens semi-directifs. Le premier cas est celui de l'autorité organisatrice de transport d'Île-de-France, suivie dans ses missions d'organisation du développement et de l'exploitation des services régionaux de transports collectifs. Le deuxième est celui d'une jeune start-up de covoiturage courte distance analysée au moment du lancement d'une expérimentation sur un territoire en grande couronne en partenariat avec les collectivités locales
It is now essential for professionals in charge of the mobility services production to take into account their users. However, most of the time they work in the absence of users : in the case of classic services, the users are inaccessible, and in the case of emerging collaborative services such as carpooling, they don't exist yet. Professionals then use various devices, such as surveys, consultation, claims processing, communication, or information system, in order to represent the users in the different dimensions of the mobility services production. This thesis research relies on interactionist, sociotechnical and commmunication approaches in order to give a global understanding of the production of these various devices generally taken separately. The main argument is that the professionals build a fiction in which the users become characters: they go back and forth between staging interactions with the users and reflecting on them through storytelling.This research relies on a qualitative study with two mobility services producers in the Parisian region based on participant observation of work situations and semi-structured interviews with professionals. The first one is the regional Public Transport Authority in charge of the design and the operation of the regional public transport services. The second one is a short distance carpooling start-up launching an experiment in partnership with local authorities in the outer suburbs of the metropolitan area

A socially sustainable transport system has to make sure that opportunities are accessible to all. The social dimension is important as transport-related barriers can contribute to social injustice. A well-functioning transport system should promote greater equity by linking people and places together. The discussion in this thesis revolves around the main concept of individual mobility. It refers to the ease with which an individual can move from one place to another to access opportunities. The main research objective of the thesis is to investigate the factors affecting individual mobility of three selected transport-disadvantaged groups, namely children, working mothers and the elderly. The thesis presents three in-depth case studies within a framework of time geography. Each study highlights the individual mobility problems confronted by the selected transport-disadvantaged group. The first case study is a detailed investigation of children’s mobility to access educational opportunities. The next chapter examines gendered mobility of working mothers and their counterparts. Finally, a walkability study is carried out to evaluate how the walking environment affects outdoor mobility of the aging population. This research employs a suite of methods in evaluating individual mobility. Children’s access to educational opportunities is examined through the computation of the size of potential path area and the number of weighted opportunities reachable within given space-time constraints. To move on, multilevel analysis is carried out to compare the daily activity spaces of married couples. Finally, a walkability assessment is conducted to evaluate factors affecting older people’s access to health-care facilities. These approaches build up to a comprehensive and holistic view to explore the issue of socially sustainable transport. By providing a more focused picture on the transport problems faced by groups which run the risks of being excluded in the mainstream transport development, this study has the potential to provide a new and comprehensive outlook in the theme of social sustainability in transport research. This thesis brings the social, spatial and temporal dimensions together in planning for a socially sustainable transport system. The results of each case study provide advice and develop initiatives to work towards a more inclusive, equitable and sustainable society. The findings from the chapter on children show that place disadvantage is an important issue to be addressed. For working mothers, the household responsibility hypothesis is evident, despite the compact city environment. The final chapter shows that active transport can benefit elderly citizens in a multitude of ways. More walkability assessments surrounding health-care and other opportunities should be looked into and audited. From the findings, the research concludes that the needs of these groups are not thoroughly addressed in Hong Kong, and related geographical research is also limited in the field. The urge to address the preferences and needs of these groups are of strategic importance. Recommendations for future research include an improved understanding of the needs among an expanded range of stakeholders and depending on the locations in where they live.

The understanding of human mobility and the development of qualitative models as well as quantitative theories for it is of key importance to the research of human infectious disease dynamics on large geographical scales. In our globalized world, mobility and traffic have reached a complexity and volume of unprecedented degree. Long range human mobility is now responsible for the rapid geographical spread of emergent infectious diseases. Multiscale human mobility networks exhibit two prominent features: (1) Networks exhibit a strong heterogeneity, the distribution of weights, traffic fluxes and populations sizes of communities range over many orders of magnitude. (2) Although the interaction magnitude in terms of traffic intensities decreases with distance, the observed power-laws indicate that long range interactions play a significant role in spatial disease dynamics. We will review how the topological features of traffic networks can be incorporated in models for disease dynamics and show, that the way topology is translated into dynamics can have a profound impact on the overall disease dynamics. We will also introduce a class of spatially extended models in which the impact and interplay of both spatial heterogeneity as well as long range spatial interactions can be investigated in a systematic fashion. Our analysis of multiscale human mobility networks is based on a proxy network of dispersing US dollar bills, which we incorporated in a model to produce real-time epidemic forecasts that projected the spatial spread of the recent outbreak of Influenza A(H1N1).

The thesis has as a general aim to analyse if and to what extent automated urban transport systems (AUTS) can provide more sustainable mobility in urban areas. AUTS is defined as a transport system with the following properties. AUTS consist of a fleet of road vehicles with fully automated driving capabilities for passenger transport on a network of roads with on-demand and door-to-door capability. The vehicle fleet is under control of a central management system in order to meet a particular demand in a particular environment. Key Findings are that various related systems and technologies which provide one or more of the functionalities of AUTS have proven to be feasible and to provide some of the benefits anticipated for AUTS. A number of early AUTS applications have already been used or tested since 1997; these systems have proven to be safe and reliable, but various perceived risks so far delayed a wider implementation. Users and stakeholders were able to envisage the potential of AUTS to improve urban mobility, but some concerns remained at this stage over technology being mature enough for systems in mixed traffic. After having used the system, public acceptance increased, as due to the innovative characteristics of AUTS, users who had no direct experience with the system before, developed a different attitude. AUTS vehicle performance parameters including acceleration, deceleration, and jerk are below benchmark values for comparable systems in terms of comfort and safety levels for passengers. AUTS as part of the multi-modal public transport system and with accompanying measures can improve .network efficiency and reduce travel times. The research has shown that there is large potential for AUTS to provide more sustainable mobility in urban areas. But a number of implementation barriers have been identified, which so far have hindered a more widespread and large-scale implementation of AUTS. Future work in this field therefore has to address these issues and to develop means to overcome these barriers in order to realise the potentials of AUTS. Furthermore sensor technologies and robotics algorithms have to be further improved, and new vehicle, infrastructure and operational concepts have to be developed for larger and more advanced systems.

The idea for this project initially came from an article i read about a small company in Stockholm, called “The cycling plumber” In the article, the founder of the company who explained that he was tired of looking for parking and sitting in traffic in his work-van around the tight and congest- ed streets of Stockholm. This sparked an interest from me, what options does the urban-operating handyman have in terms of transportation? Using the design process and thorough user studies, this project explores a new type of commercial vehicle segement, intended for carpenters operating in the dense city traffic of the future. The final product proposed, is called VW Artisan. It’s a versatile commercial vehicle utilizing a detachable toolbox system to improve the efficiency and comfort of the user during their daily work.
Idén till detta projekt kom ursprungligen från en artikel som handlade om ett nytt företag i Stockholm, kallat “Cyklande rörmokaren”. I artikeln förklarade grundaren till företaget att han hade tröttnat på att sitta i köer och leta efter parkering runt Stockholms tätt trafikerade gator. Detta väckte ett intresse för mig. Vilka transportalternativ har en hantverkare som huvudsakligen arbetar i större städer? Med hjälp av designprocessen och utförliga användarstudier utforskar detta projektet en ny typ av kommersiellt fordonssegment, avsett för hantverkare i framtidens tätt befolkade städer. Slutresultatet som föreslås i detta projekt kallas för VW Artisan. Ett mångsidigt arbetsfordon med en avtagbar verktygsvagn för att effektivisera och öka komforten i användarens dagliga arbete.

Hall effect and resistivity measurements have been carried out as a function of hydrostatic pressure and temperature on a number of samples of indium phosphide ranging from exceptionally pure to highly doped. In the case of pure and lightly doped InP an iterative solution of the Boltzmann Equation has been used successfully to describe the temperature and pressure dependence of mobility over the helium temperature range. Measurements on the highest mobility samples of InP ever grown suggest that the conduction band deformation potential is 6. 7eV. For the case of highly doped material it was found that a theory of scattering from a correlated distribution of impurities describes both the temperature and pressure dependence of mobility well. Pressure dependent mobility measurements on a sample having an impurity density close to the Mott transition suggest that the inclusion of impurity band conduction in the analysis is necessary even at nitrogen temperatures and above. Such an analysis is used successfully to describe the temperature and pressure dependence of both mobility and Hall carrier concentration.

In the last three decades the global population has been growing at an essentially constant rate, at around 1.5 per cent per year, to about 6.026 billion in 2000 when it was estimated that 47% of that population live in an urban environment. Further, a United Nations’ projection indicates that 60% of the total global population may be living in an urban settlement by the year 2025. This increasing urbanisation brings with it increased employment, that delivers affluence, which then continues the cycle of migration and movement to these growing metropolitan areas in both developed and developing countries. As cities increase in population and expand their urban area, there is a consequential expansion of urban transportation and accompanying service infrastructure. People travel daily, irrespective of their vast differences in culture, economic conditions and means of transportation. This daily mobility is sought for its own sake as well as to bridge the spatial distance that separates their homes from the work place, to accomplish their household’s domestic needs and to undertake social journeys, such as visiting friends and taking holidays. As the world’s urban population undertakes its daily mobility by a variety of transportation modes, an individual’s mobility behaviour and mode-choice is governed by a complex matrix of physical and human, social and management indicators, measures and/or drivers. A literature review describes the current understanding of this complex matrix and concludes by identifying and defining a set of fundamental underlying measures that drive private motorised, public transport and non-motorised (walking and bicycling) mobility at national, city and household levels. As practical instruments, transportation models play an important role in providing decision-makers with analytical tools to help them understand their city’s transportation and the different future scenarios it may face. While not necessarily producing foolproof information or predictions, models are still the best methods available to test the likely implications of alternative transportation policy decisions in a rapidly changing urban environment. Urban transport models are generally based on the notion that traffic can be modelled in aggregate measures through statistical data and predictive modelling techniques. In this research, dimensional analysis is used to derive sketch-plan models for private motorised, public transport and non-motorised mobility for any urban environment based on four-decades of detailed land-use and travel pattern data from a large international sample of cities. These models are developed on the basis of a set of fundamental underlying measures that are deemed to drive private motorised, public transport and non-motorised (walking and bicycling) mobility at the city level. Importantly, the models also embody three key attributes. They are: • easy to use, minimising user requirements and data inputs • policy-sensitive, capable of assessing a sufficient range of policy options • reliable and robust over time, so that the results can be consistently believed. The capacity of the sketch-plan models to predict personal mobility in an urban environment is statistically validated against an independent land-use and travel pattern data set for 83 cities located on five continents. Despite their simplicity and maintaining a consistent functional form over a time-series of four-decades and across all geographic and cultural regions, the private motorised mobility model can consistently explain up to 92% of the variance in private motorised urban mobility. The results for the public transport mobility model are less reliable and consistent, in particular when developing cities are part of the model. Results for developed or wealthier cities are much better. Reasons for these results and their inadequacies are discussed. The non-motorised modes mobility model is the least successful part of the modelling work. This can be attributed to a combination of inadequate data and, very likely, the more micro-level determinants of usage of these modes. The private motorised urban mobility sketch-plan model equation developed in this thesis is able to predict present and future trends of automobile use in individual cities to a high degree of statistical reliability. The model equation offers urban transport planners a focused direction on the fundamental measures that have the potential to control and deliver automobile restraint policies and strategies. A series of case studies shows that this model has wide applications in understanding past trends in private motorised mobility and in developing urban environmental strategy and policy through its ability to calculate and assess current and future motor vehicle emissions inventories in cities. The thesis makes suggestions for future work in this area of metropolitan level transport modelling, in particular, how to improve the public and non-motorised transport models so that total urban transport mobility can be better understood and modelled.

The trend of an increasing number of student travellers from the University of the North, the University Centers of Koprivnica and Varaždin also affects the quality of their mobility. The mobility of student-passengers in rail passenger transport is directly related to the quality of service and the inevitable maximum safety aspect, but also to the appropriate railway infrastructure. According to the above, it is necessary to analyse the current state of transport infrastructure and propose activities to increase the mobility of student-passengers. This paper analyses the current status of student-passenger mobility in railway passenger transport, and also analyses the regional features of road and railway transport infrastructure, state road DC-2 and railway R202 Varaždin-Dalj, located between the cities of Varaždin and Koprivnica, with regard to route characteristics and infrastructure facilities. As part of the work, a survey was conducted through questionnaires, and questionnaires were completed by students-travellers of the University of the North.

Traffic system analysis and planning is a very complex process that requires quality input data collected on a relevant sample and over a relevant time period. The project Sustainable Urban Mobility Boost Smart Toolbox aims at development of the methodology (toolbox) in data rich reality, which is combining traditional and novel data science approach for transport system analysis and planning. It enables digital transformation of existing (traditional, ingrained) analytic methodologies by novel utilization of mobile network infrastructure as urban mobility data sources (spatio-temporal data on population migrations gathered from anonymized mobile network logs) and data science capabilities. The project is funded by the EIT Urban Mobility Regional Innovation Scheme RIS 2020. The end product will provide transport planners with insight in spatial distribution of commuters and their transport means. Also, it will propose methodology for the identification and implementation of the measures for improvement of the transport system based on input data. Primary goal of the Project is to provide universal methodology suitable for any city to create sustainable transport system.

The smart mobility is a concept, where with various past and real-time data, and with the help of information and communication technologies, travel time is optimized, resulting in reductions of space usage, road congestion, road accidents and emissions of harmful gases and noise. [1] For implementation of smart mobility it will be necessary to combine sustainable solutions and smart innovations at the same time. This will contribute for moving forward in developing cities, which are lacking behind considering inclusion of smart mobility in their urban transport systems. Also, smart mobility will contribute for improved environmental footprint of urban transport, having in mind that environmental issues (air pollution in particular) in these cities are very serious. More specifically, the paper identifies implementation framework for smart mobility, along with drivers and barriers for its implementation, as well as strategies in transport that are environmentally friendly. Turning carbon-dependent transport sector in developing cities into a clean and smart mobility system might seem like a mission impossible. But, it can be done and it is also a must, given the current transport system’s impacts on the environment and public health [2]. At the end, this is an indispensable opportunity to start with changes and to build a better and sustainable future.

The development of traffic that is conditioned by the high mobility of people, goods and services must be in line with the principles of sustainable development, but it is only possible if the consumption of renewable resources is less than natural renewal opportunities. The future is in implementation of innovative technologies such as telematics systems that offer not only technical solutions but also a new way of life, a new business approach and a new cultural aspect of living for all traffic participants. Advanced telematics solutions such as inflow management and speed limit management greatly help to solve traffic problems, like incidents, environmental pollution, traffic congestion, fuel consumption, etc. Impact of telematics can increase safety but can also introduce new risks for drivers that pose special challenges to traffic psychology and public health. In order to reduce traffic congestion, longer waiting times, environmental pollution, reduce fuel consumption in incident situation various advanced grammatical solutions have been implemented in order to reduce these problems. Telematics, using techniques such as informatics, optoelectronics, automatics and telecommunications, helps to reduce costs of transportation potential management, improves the security and reliability of the transportation service.

Vehicles with internal combustion engines (ICE) currently represent the most prevalent form of road transport. Although level of emission per vehicle have drastically decreased, their emissions have significant impacts on the environment and health. The emergence of vehicles powered by more environmentally friendly systems has resulted in a change in perceptions, as they result in a reduction in pollution and other negative impacts of the transport system. It is for this reason that the goal has been set, to reduce the market for vehicles with only internal combustion and focus on encouraging the purchase of more sustainable options. The aim of this paper is to review the regulations in the field of passenger car markets in the European Union, and to establish historical trends, as well as to identify goals for future market development.

The urban population of Africa, the fastest urbanizing continent, has increased from 19% to 39% in the past 50 years, and the number of urban dwellers is projected to reach 770 million by 2030. However, while rapid urbanization has increased mobility and created a subsequent growth in demand for public transport in cities, this has not been met by the provision of adequate and sustainable infrastructure and services. The majority of low-income residents and the urban poor still lack access to adequate transport services and rely on non-motorized and public transport, which is often informal and characterized by poor service delivery. Lack of access to transport services limits access to opportunities that aren’t in the proximity of residential areas, such as education, healthcare, and employment. The urban public transport sector not only faces the challenge of poor service provision, but also of gender inequality. Research shows that, in the existing urban transport systems, there are significant differences in the travel patterns of and modes of transport used by women and men, and that these differences are associated with their roles and responsibilities in society. Moreover, the differences in travel patterns are characterized by unequal access to transport facilities and services. Women are generally underrepresented in the sector, in both its operation and decision-making. Women’s mobility needs and patterns are rarely integrated into transport infrastructure design and services and female users are often victims of harassment and assault. As cities rapidly expand, meeting the transport needs of their growing populations while paying attention to gender-differentiated mobility patterns is a prerequisite to achieving sustainability, livability and inclusivity. Gender mainstreaming in urban public transport is therefore a critical issue, but one which is under-researched in East Africa. This research explores gender issues in public transport in East Africa, focusing in particular on women’s inclusion in both public transport systems and transport policy decision-making processes and using case studies from three cities: Nairobi, Kampala and Dar es Salaam.

Research into the fate of pharmaceutical compounds (PCs) in the environment has focused on aspects of removal efficiency during sewage treatment, degradation in surface water and accumulation in soils and sediments. However, very little information is available on the binding interactions of pharmaceuticals with dissolved organic matter (DOM) originating from wastewater treatment. Such interactions can significantly affect the transport potential of PCs in soils by altering compound affinity for soil particle surfaces. Our primary hypothesis is that the transport potential of PCs in soils is strongly impacted by the type and strength of interaction with DOM and the stability of resulting DOM-PC complexes. The overarching goal of the proposed work is to develop a better understanding of the risk associated with introduction of PCs into the environment with treated wastewater. This goal has been achieved by elucidating the mechanisms of the interaction of selected pharmaceuticals (that have shown to be widespread wastewater contaminants) with DOM constituents; by determining the stability and fate of DOM-PC complexes introduced to soils and soil constituents; and by evaluating the potential uptake of these compounds by plants. Based on the results obtained in this study (column and batch sorption-desorption experiments), we suggest that PCs can be classified as slow-mobile compounds in SOM-rich soil layers. When these compounds pass this layer and/or are introduced into SOM-poor soils, their mobility increases significantly. Our data suggest that in semiarid soils (consisting of low SOM), PCs can potentially be transported to the groundwater in fields irrigated with reclaimed wastewater. Moreover, the higher mobility of the acid PCs (i.e., naproxen and diclofenac) in freshwater column systems suggests that their residues in soils irrigated with reclaimed wastewater can leach from the root zone and be transported to the groundwater after rain events. Our data obtained from the binding experiments of PCs with DOM demonstrate that the hydrophobic DOM fractions were more efficient at sorbing PCs than the more polar hydrophilic fractions at a pH near the pKa of the analytes. At the pH of natural semiarid water and soil systems, including that of reclaimed wastewater and biosolids, the role of the hydrophobic fractions as sorption domains is less important than the contribution of the hydrophilic fractions. We also hypothesize that the DOM fractions interact with each other at the molecular level and do not act as independent sorption domains. In summary, our data collected in the BARD project demonstrate that the sorption abilities of the DOM fractions can also significantly affect the mobility of pharmaceutical compounds in soils influenced by intensive irrigation with treated wastewater or amended with biosolids.

Urban transportation is on the one hand a vital component of a city and on the other a major factor of concern. The latter is due to the high impact on air pollution, carbon dioxide emissions, and fatalities. This is not just caused by the mobility of people but also, and increasingly, by the need to transport goods. Cities in Central Asia are often associated with strong air pollution and rising greenhouse gas emissions from urban transport contradicting the global strive for a carbon-neutral world by 2050. In the light of sustainable development, it is, therefore, the objective to reduce the externalities of urban mobility and urban logistics jointly. The German-Kazakh University in Almaty envisions fostering the transformation to sustainability in Central Asia by setting up a climate center. One pillar will be urban transport. In this working paper, an interdisciplinary team of experts from Kazakhstan and Germany investigates fields of action and research for this center. The team describes stakeholders to involve, potential funding opportunities, and first actions for each of the identified fields. The working paper provides a fruitful basis for academics and partners to set up the center and to involve new partners.
