AbstractTransport has an immense impact on the environment. The largest share of environmental pollution is caused by road transport. The atmosphere is threatened by fuel combustion of engines of road vehicles, thereby leading to the global warming of Earth. In addition to having an adverse impact on the environment, such as greenhouse gas emissions and carbon dioxide emissions, road transport also leads to external effects such as noise pollution, vibration, congestion and traffic accidents. The volume of transport in the world, notably on the roads, is increasing day by day. We should take the necessary steps to move to more environmentally-friendly modes of transportation, such as rail and inland navigation. Rail transportation is currently the largest competitor of road transport. If the waterways infrastructure is improved, there would be a decrease in the traffic flow of motorways and thus, we can move to a more environmentally-friendly transportation.

Full textAbstract:
Freight transportation modes consume enormous amounts of energy. This paper estimates the long- and short-run effects of fuel prices on freight volumes in various modes of transportation in Shanghai. Data included monthly changes during the period 2009–2016. Air cargo series were suggested to include one or two unit roots, and hence were removed from the cointegration analysis. Both the Phillips–Ouliaris and Johansen tests did not detect long-run relationships between real fuel prices, water cargo, road, and rail freight. Conventional first-differenced VAR (vector autoregressive) models were estimated. Overall, whether in the short- or long-run, real fuel prices did not influence freight transportation volumes. However, we found a Granger causality running from rail to road freight, as in the short-run (one month), a 1% change in rail freight would lead to a reduction of 0.07% in road freight. Therefore, simply by increasing fuel prices, the government could seldom encourage the shift from energy-inefficient modes of freight transportation to energy-efficient ones to achieve a sustainable freight transport. The allocation of more time and routes for rail freight traffic and the reduction in rail freight taxes may increase the rail freight volume and hence decrease the overall energy use. Our findings, to some degree, contribute to freight transportation economics. Future research may examine the impact of gasoline prices or diesel prices on freight traffic volumes.

Objective : In this study, we proposed the concept of the particulate matter footprint (PM Footprint) and assessed the PM Footprint in transportation modes (road, rail, and water transportation). In addition, we assessed the contribution of secondary particulate matter formation gas emissions, which contribute to particulate matter formation.Method : To calculate the PM Footprint in the transportation sector, the ReCiPe life cycle impact assessment method in life cycle assessment (LCA) was used. For the PM Footprint of each transportation mode, the life cycle inventory data were multiplied by the characterization factors of PM<sub>10</sub>, PM<sub>2.5</sub> and secondary particulate matter formation emissions such as NOx, SOx, NH<sub>3</sub>. The PM Footprint values were shown in kg PM<sub>2.5</sub> eqv. value.Results and Discussion : The road transportation (trucks) had a much higher PM Footprint value than rail and water transportation in tkm unit based. In the road transportation mode, small size truck such as 3.5 tons (1.37E-03 kg PM<sub>2.5</sub> eqv./tkm), 3.51~5 tons (9.65E-04 kg PM<sub>2.5</sub> eqv./tkm), 1.25 tons (8.38E-04 kg PM<sub>2.5</sub> eqv./tkm), and 1 ton (7.83E-04 kg PM<sub>2.5</sub> eqv./tkm) had higher PM Footprint value than big size trucks. In the rail transportation mode, the diesel rail transportation had the highest PM Footprint value, followed by electric + diesel rail transportation and electric rail transportation. In the water transportation mode, the tanker LNG_100 dwt had the highest PM Footprint value, followed by ro-ro ship coastal, and tanker coastal 500~20,000 dwt. The secondary particulate matter formation emissions (NOx, SOx, NH<sub>3</sub>) contributed to PM Footprint value with 59% in road transportation, 80% in rail transportation, and 61% in water transportation. Conclusions : The PM Footprint values, which shown in this study and the results of the directed polluted PM and secondary gas emissions should be considered for national PM reduction policy and planning. Finally, a certification system using the PM Footprint in this study should be developed and settled down for national PM reduction.

Goods movement using container are quite efficiently assessed because it can carry a great amount of goods fit to container capacity. Freight transportations is a primary component of all supply-chain and logistics systems, but in contrary using a truck as its transportation means causing many problems such as air and noise pollutions, traffic congestions, road accidents and road damage. Depart from this facts, so government is looking for another means of freight transporter which more efficient with a bigger load capacity advantages. This options goes to train as a solutions of intermodal freight transportations lack. In order to supporting intermodal freight transportations, right now double track of railway is available for Jakarta – Surabaya route (Northern line route). By now, noted that freight transportation with double track railway frequency is potentially increase to 15 trip per days with capacity 500 TEU (Twenty feet Equivalent Units) per days and fuel consumptions (with truck) can be thrifted into 115 kl per days also reducing carbon monoxide emission amounts 350 tons per days. According with an official statements from Directorate General of Railways, Ministry of Transportations, explained that Jakarta – Bojonegoro route on double track railway is fully operated so this paper is conducted to determining feasibility of railway structure performance due to freight intermodal transportations at Bojonegoro – Kalitidu route. Railway structure performance feasibility is observed from loading distributions, rail strength, rail sleeper strength, and railway subgrade endurance to planned freight trains. As a result of this research obtained that tension force that occurred on rail is 830,10 kg/cm2 < permitted tension on rail (first class rail) 1325 kg/cm2. So, tension force that occurred on rail is safe. Moment force that occurred on rail bottom is 14521,25 kg.cm < permitted moment force (150.000 kg.cm) Moment force that occurred in the middle of rail sleeper is 58993,978 kg.cm < permitted moment force (93000 kg.cm). Tension force that occurred on above railway subgrade (σ2) is 4,17 kg/cm2 < qu (29,671 kg/cm2). It means that railway subgrade is capable to supporting load of freight transportation operations along Bojonegoro – Kalitidu route.

Full textAbstract:
In order to solve the environmental protection problem of carbon emissions in the field of freight transportation, this article proposes to promote the transfer of road freight transportation to railway transportation within a reasonable range by levying carbon emission taxes. To propose an applicable solution, this paper establishes a comprehensive carbon emission system model in the field of road transportation and railway transportation to simulate a closed-loop system as comprehensively as a real transportation system, determines the system elements according to the actual situation, reasonably develops the model hypothesis scheme, and draws out the causal network. On this basis, the system flow diagram and corresponding structural equations are constructed, and the model parameters are estimated. Finally, the paper uses actual data to verify and simulate the system model. A reasonable carbon levy interval has been obtained, and the carbon levy within this interval can promote the transfer of road freight transportation to railway transportation, so as to achieve the purpose of decreasing total carbon emissions of road–rail transportation systems in an orderly way. The innovation of this paper is to construct the carbon emissions of the road–rail system systematically for the first time, and to conduct research and exploration of carbon levies on this basis.

Full textAbstract:
In recent years, China keeps working on restructuring the country’s multimodal transport and highly develops the high-speed rail (HSR) infrastructure to improve transport efficiency. As the economic engine of China, the Yangtze River Delta region keeps leading the HSR development and the transporting modal transformation within the whole country. The fast development of HSR on the one hand highly improves passengers’ travel efficiency and, on the other hand, releases the capacity of conventional rail infrastructures to support regional multimodal freight transport. This study applies a three-level AHP structure and constructs a comprehensive index to evaluate the development of a rail-based multimodal freight transport network including railway, rail-water, and rail-road. The comprehensive index contains 14 quantitative and 8 qualitative indexes, covering the rail-based infrastructures, multimodal transport capability, freight transport performance, and transport sustainability. The comprehensive index is then applied to analyze the rail-based multimodal freight transport for the Yangtze River Delta region. The operational data of 59 freight stations and more than 200 railway links of the Yangtze River Delta were recorded. About 172 valid questionnaires were collected to score the qualitative indexes, and all the quantitative indexes are scored based on the real-life freight data. The results reveal the impacts of HSR development on rail freight transportation and show that Zhejiang has led rail freight transportation while Shanghai mainly leads the waterway freight transportation. Meanwhile, Anhui performs very well on road-rail transportation and Jiangsu has made a great improvement on water-rail transportation.

Purpose This paper aims to understand the trade transportation situation between China and Koreas, and to explore the possibility of establishing the surface transportation corridor between China and Koreas in the future. Moreover, the paper also intends to find out the mode choice behaviors of shippers, which can be used to analyze the substitute effects of the surface modes on the water one. Design/methodology/approach The paper first analyzes the Sino-Korean bilateral trade and the corresponding trade transportation between China and Koreas. Secondly, it presents the surface transportation network between China and Koreas, and analyzes the warming relations between the North and South. Finally, the modal split of trade transportation between China and Koreas is estimated by establishing a mode choice model based on a questionnaire survey. Findings With the increasingly stable political environment and the physical highway and railway connections, the surface transportation network would become possible. Moreover, the shippers need the multimodal transportation system between China and Koreas, and many shippers would select road or rail mode if a suitable road or rail network were available. Especially, between China and South Korea, the road, rail and water mode may be used evenly, while the road mode may play a more important role between China and North Korea. The surface modes would have a huge substitute effect on the water mode. Originality/value The existing literature conducted research mainly from the perspective of economy and geopolitics, while the topics of transportation between China and Koreas are rarely concerned. This paper intends to throw some light on the situation of the trade transportation between China and Koreas, consider the potential of relation improvement on the Korean Peninsula proactively and study the surface transportation issues between China and Koreas.

This article focuses on recent railway projects in Selenge and Gobi provinces in Mongolia by addressing railway plans and narratives from a historical perspective. New imaginations and expectations have arisen in connection with planned rail infrastructures such as the “Steppe Road,” which to date only exists on the papers of planners and in the minds of residents. Taking the insight by Morten Axel Pedersen and Mikkel Bunkenborg that roads may act as “technologies of distantiation,” this article further argues that railroads not only connect but also separate, traverse, and disperse. Thus, the critical question remains whether the rail system connects Mongolia or whether is it rather used as a transit zone for outside interests.

Full textAbstract:
The impact of rail transportation on road vehicles that are placed in flatcars is considered in the article. The features of piggyback transportation and the dynamic forces acting on road vehicles in railway rolling stock are determined. The change dependences of the values of dynamic forces for different masses of road vehicles in the longitudinal and transverse directions are established. It is concluded that road vehicles that are used in regular piggyback transportation will experience significant dynamic loads of structural elements, which requires monitoring of their technical condition. Consequently, the infrastructure of piggyback terminals that load and unload road vehicles onto railway rolling stock should include the availability of automobile service facilities.

Railways are facing a serious problem of road vehicle–train collisions at unmanned railway level crossings. The purpose of the study is the development of a safe stopping sight distance and sight distance from road to rail track model with appropriate computation and analysis. The scope of the study lies in avoiding road vehicle–train collisions at unmanned railway level crossings. An intelligent and autonomous framework is being developed using supervised machine learning regression algorithms. Further, a sight distance from road to rail track model is being developed for road vehicles of 0.5 to 10 m length using the observed geometric characteristics of the route. The model prediction accuracy obtained better results in the development of a stopping sight distance model in comparison to other intelligent algorithms. The developed model suggested an increment of approximately 23% in the current safe stopping sight distance on all unmanned railway level crossings. Further, the feature analysis indicates the ‘approach road gradient’ to be the major contributing parameter for safe stopping sight distance determination. The accident prediction study finally indicates that, as the safe stopping sight distance is increased by following the developed model, it is predicted to decrease road vehicle–train collisions.

High-speed rail is a form of self-guided ground transportation, which utilizes steel-wheels or magnetic levitation (i.e., Maglev) and can travel in excess of 200 miles per hour. High-speed ground transportation (i.e., HSGT) has been widely used in Europe and Asia, but the debate continues over the usefulness of high-speed rail in the United States. Several metropolitan areas in the United States have been identified as corridors that would benefit from HSGT. High speed rail can offer an alternative or a compliment to over-the-road and air transportation. Initial investment cost for this mode of transportation are high, but other factors such as fewer emissions from trains help to balance these costs. This manuscript examines the feasibility of bringing high-speed rail to clusters of cities throughout the United States (i.e., corridors) for passenger and commercial freight transportation.

This study estimates the impact of major road supply on individual travel time expenditures (TTEs) using data that cover 30-year variations in transportation infrastructure and travel behavior. The impacts of the supply of road and rail infrastructure are estimated with a data set that combines records of large-scale household travel surveys in the Tokyo metropolitan area conducted in 1978, 1988, 1998, and 2008. Linear and Tobit models of individual TTEs are estimated by following the behavior of birth cohorts over the 30-year period. The models incorporate the changes in transportation infrastructure, measured as lane kilometers of two levels of major road stock and vehicle kilometers of urban rail service. The results show significant negative effects of lane kilometers for higher-level and lower-level major roads on the TTEs for all travel purposes and for commuting, after controlling for socioeconomic backgrounds and generations of individuals. This study discusses that, in Tokyo, the estimated effect is more likely to reflect the effect of a major road network per se on individual TTEs than the (indirect) effect of major road supply on individual TTEs working through land development activities (i.e., induced car travel demand). For example, the caveat is that actual road investment decisions still need to consider the induced component of road traffic in addition to the (direct) effect that is estimated in this study.

Intermodal transportation is characterized by the transfer of goods from the origin point to a destination, involving two or more different modals of transportation. This paper aims to analyze modal road and rail transportation in the Campos Gerais region, as a form of concentrated cargos (storage and distribution) in this region. The empirical secondary data was obtained from federal agencies, such as the Ministry of Development and Instituto Brasileiro de Geografia e Estatística (IBGE). The modal choice emphasizes each specific characteristic and costs cutting. The Campos Gerais region presents significant exports, representing 41% of the state of Parana in 2004. The logistics junction of Campos Gerais region is focused on modal road-rail, centering on a large volume of cargo in this region.

This work aims to present the current scenario of the Brazilian raw sugar export logistics, focusing on transportation, pointing out the benefits of intermodal road-rail in the flow of bulk sugar from mills to the Port of Santos. The study analyzes the evolution of modes of transportation and new investments focused on port infrastructure. It is possible to notice throughout the work that most of the investments in the area comes from private business groups seeking partnerships to improve competitiveness for the sector, such as Rumo Logística and America Latina Logística, which holds the largest concession and rail network in the state. The state of São Paulo currently offers transshipment options warehouses located in its territory and can meet the demand of the sugar mills to flow their product. It could be identified that the existence of a logistical planning well done using these two modes (road and rail) can guarantee competitive prices, load security and a transit time that does not compromise the receipt of the goods at the port, which historically suffer from the accumulation of vehicles, and is a great alternative for reducing air pollutants, with the reduction of vehicles circulating on the roads.

Abstract Land use-transportation comprehensive planning has become an increasingly common technique in regional and sub-regional planning processes. Since land use management strategies act as an effective tool to achieve transportation planning objectives, it is important to identify the relationship between land use pattern and travel behaviour. This study examined the relationship between transportation and land use in Rajshahi city. Rajshahi is a major urban, commercial and educational centre of Bangladesh. In Rajshahi, Shaheb bazaar zero points to New Market road is one of the most important roads. After construction of this road in 2013 intense development has taken place beside it. To identify this primary relationship data has been collected from different types of field survey. Then the impact of land use and transportation has been determined by comparing with the previous database. The findings of the study show that there exist a reciprocal relationship between land use and transportation system and the impacts on both. The study also notes that the impact of transportation on land use is more than the impact of land use on transportation. The study will help to control the haphazard growth and traffic congestion of the concerned area in the future.

Rail-road transhipment yards serve as interchange points between rail and road providing transhipment of loading units. These yards are of great importance for smooth functioning not only of railways but also of the whole intermodal transportation chains. The problem of choosing location of railway facilities, such as yards and depots, has great practical importance and is widely considered in the literature. In this paper, we present a multi criteria decision making (MCMD) model for selecting the most suitable micro location of a rail-road transhipment yard. The developed MCMD model is based on combining a compromise programming technique with the theory of fuzzy numbers. This approach was chosen to solve the considered location problem due to the specific decision-making environment that reflects in the presence of non-commensurable and conflicting criteria. As a case study we analysed several alternatives for locating rail-road transhipment facilities in the area of the rail freight yard in Vršac. The results confirm validity and usefulness of this approach.

Toronto is widely perceived to have developed efficient solutions to transportation during periods of rapid population growth, attributed largely to significant investment in public transit and effective means of managing growth in an orderly manner. Relative to comparably sized cities elsewhere in North America, the downtown has flourished and urban sprawl appears to have been contained within reasonable limits. Yet, despite a high degree of centralized planning and policies that favor transit over road improvements, on a regionwide basis, both modal split and transit ridership have actually declined, road congestion has reached serious levels in outlying regions, and the central area is losing its dominance as the location of new employment creation. This experience suggests a need to rethink the advisability of continued preoccupation with rail-dominated (subway, light rail transit, and high-technology transit), centrally oriented, capital-intensive transit improvements at the expense of lower-cost (and lower political profile) operational enhancements of surface transit, more effective means of dealing with road congestion, and greater reliance on business principles in the provision of transit service. In particular, there is a need to rethink government policies that favor capital over operational improvements, cost-based subsidy formulae that reward high costs rather than performance, intergovernmental transfers that obfuscate real costs perceived at the local decision-making level, and evaluation procedures that rely on alleged social and environmental advantages wherever reasonable ridership estimates fail to justify the selection of a preconceived preferred technology in assessing the true viability of new projects.

Intermodal transportation is becoming more and more willingly used in the goods supply chain in view of its specific, flexible characteristics. In Poland, intermodal transportation is based primarily on land-sea and rail-road transportation, using mostly containers. The most frequently used containers in 2017 were the 40-feet containers which accounted for over 57% of all containers transported. Contribution of the railway transportation in intermodal transportation is increasing every year. Despite the slow growth, both, planned as well as already carried out investments in intermodal terminals, indicate continuous growing pattern. Many operators strive to improve the technical condition of nodal and linear infrastructure that leads to raising the quality of services provided. Large number of investments aimed at improving the functioning of intermodal transportation in Poland are made by PKP PLK S.A which is the conductor rail operator. The most important of them include improvement of the railway lines technical condition of the major routes, that would increase the average operational speed. The largest intermodal terminal in Poland is the DCT Gdańsk located in the Northern Port in Gdańsk. The annual transshipment ability of the terminal after the investments made is set at 3 million TEU. The terminal is connected with the hinterland by road and rail connections. Due to high quality technical equipment it is able to serve up to 9 trains a day which adds up to almost 300 trains per month. It provides railway connection to almost all overland intermodal terminals in the country. DCT Gdańsk gladly invests in development of the railway transportation and endeavour to achieve rail system development not only at the terminal, but also throughout Poland.

In order to investigate the intrinsic relationship between residence choice and urban rail transit, this paper establishes a housing valuation model, explores the interface link between the rail transit and other transport modes by the establishment of a model, and also obtains the family transportation impedance. According to the balanced housing price, the various districts’ hedonic cost, and the generalized transportation impedance, the attractiveness of the various districts with respect to each mobile home is obtained. Satisfaction of any resident is received by establishing a close degree model. Due to the satisfaction and the price, we construct a largest consumer surplus model and then obtain the residence of the greatest consumer surplus for mobile home. Numerical example’s result indicates that all high-income mobile homes will chose the residence for the commute destination district, especially the one in the suburbs. Furthermore, the low-income families chose the residence for the commute destination district, which has the rail transit if the income is allowed, or the nearest district to the destination with rail transportation if not. This illustrates that whether a road having urban rail transit plays a significant impact only on the low-income family residence choice when the commuter routes pass through the road and almost has no influence for other families. Hence, it is shown that the reasonable urban planning is important and that urban rail transit should form a network that will play a key role.

AbstractA lot of substances and items are transported by road, sea, rail and air every day. The biggest hazard is created by the transportation of hazardous substances with flammable, caustic or toxic properties. The hazard level increases if such substances are transported through densely populated areas. Traffic intensity, the technical condition of vehicles, drivers’ errors or ignorance and non-compliance with legal regulations are examples of factors that can lead to potential failures in the transport sector. Accidents can cause an uncontrolled release of dangerous gases or liquids, resulting e.g. in environmental degradation or a hazard to humans. The article presents the issues related to the hazards presented by road transportation of hazardous materials. Examples are shown of potential effects of accidents and hazard zones arising due to a release of selected hazardous substances, such as chlorine, ammonia, petrol, diesel oil or LPG.

Introduction. At present the transportation of current high-capacity containers in road-rail mixed network is carried out only by means of the specialized sites with the equipment for their reloading. The number of such sites on the railway transport network in the Russian Federation is significantly fewer than the number of conventional cargo railway stations without such equipment, which leads to distance, time and cost of delivery increasing, the efficiency of the road transport use reducing due to a large downtime. The transportation of high-capacity containers by road rolling stock (RS) is often carried out over the considerable distances in the reverse direction by rail. In order to eliminate these shortcomings, the authors of the article formulated the purpose of the work – the development and evaluation of the efficiency of the technology of goods transportation in high-capacity containers with load lifting stays in a road-railway network based on a transportation case study. Within the framework of which a new design of a container with load lifting stays has been developed which allow to carry out loading and unloading operations with the container at conventional cargo railway stations without the use of specialized equipment of container terminals, as well as the efficiency evaluation of the technology of the containers transportation in road-rail network based on a case study.Materials and methods. The study uses the following methods of theories: cars operation, car operational properties, transport processes; analytical and numerical methods.Results. It has been determined that the cargo delivery time according to the new technology of transportation of high-capacity containers with load lifting stays from the Volga brewery to Novosibirsk has decreased by 24.6%, the time of operation of road RS has decreased by 10 times, and the annual economic efficiency of the new technology application is 1.55 million rubles in comparison with the current technology.Discussion and conclusions. Based on the case study of the use of a new technology for the transportation of high-capacity containers with load lifting stays in a mixed network it has been found that this technology allows: A) to reduce the number of delivery operations by 24%; B) to reduce the delivery time by 24.6% and the operation time of motor transport by 10 times. C) to obtain the annual economic effect of the application of the new technology in the amount of 1.55 million rubles.

Full textAbstract:
Traffic accidents are a painful and costly affliction all over the world. The discussion and debate over the most effective measures to adopt to enhance road safety is often based on folk theories and is not free of private interests and pressures. Road traffic is a complicated system of interactions providing transportation services. Unfortunately, in conjunction with these services, traffic accidents, an awful public bad, are produced. The purpose of this paper is to study the production relationship, for inter-city transportation, between the physical factors, i.e., highways and vehicles, and traffic accidents. The upshot is prediction ability of accidents in any given road segment, existing or planned. The regretful aspect of roads runs counter to conventional wisdom which, failing to appreciate the quantitative relationship between roads and accidents, often advocates building more and wider roads as the remedy. The empirically substantiated public bad property of roads, by way of production functions for traffic accidents, is useful for public policy, concerning the investment in highways versus other forms of transportation, such as rail. They also promote better understanding of traffic accidents and their data and the methodology allows testing hypotheses relating to safety policy. This study sheds light on the enigma of the long-term decline in the probability of death on the road, as observed in many countries, by attributing it to the rising traffic density. The estimation also sheds light on the accident-externality imposed by road users on others. The results suggest that for inter-city roads the risk of fatal and severe accidents is over-internalized by road users as the marginal effect of traffic flow is smaller than the average.

The sustained and stable growth of China’s market economy promotes the continuous improvement of transportation demand and puts forward higher requirements for transportation products. At present, as a new product, high-speed rail freight has played an important role in cold chain logistics and high-value-added transportation, which is of great significance to effectively reduce the pollution caused by road transportation and further promote the sustainable development of economy and logistics industry. In the previous study, we studied the organization optimization method of high-speed rail freight train operation scheme and the compilation method of high-speed rail freight train diagram based on the overall demand of freight transportation but did not consider the influence of different high-speed rail freight transportation products on the organization scheme. Therefore, in order to ensure the sustainable development of high-speed rail freight business, based on the demand of high-speed freight products (the freight product for short in the following text), this paper focuses on the optimization method of high-speed rail freight train organization scheme considering different demands. A two-stage freight demand analysis method considering customers’ choice intention and actual supply capacity was designed, comprehensively considering the relationship between operation cost and income, and a model based on different products in order to meet the needs of large-scale case solving was established. In addition, a column generation algorithm was designed. The computational results are encouraging and demonstrate the effectiveness of the model and solution method.

Full textAbstract:
In this study, the author focuses on modeling and optimizing a freight routing problem in a road-rail intermodal transportation network that combines the hub-and-spoke and point-to-point structures. The operations of road transportation are time flexible, while rail transportation has fixed departure times. The reliability of the routing is improved by modeling the uncertainty of the road-rail intermodal transportation network. Parameters that are influenced by the real-time status of the network, including capacities, travel times, loading and unloading times, and container trains’ fixed departure times, are considered uncertain in the routing decision-making. Based on fuzzy set theory, triangular fuzzy numbers are employed to formulate the uncertain parameters as well as resulting uncertain variables. Green routing is also discussed by treating the minimization of carbon dioxide emissions as an objective. First of all, a multiobjective fuzzy mixed integer nonlinear programming model is established for the specific reliable and green routing problem. Then, defuzzification, linearization, and weighted sum method are implemented to present a crisp linear model whose global optimum solutions can be effectively obtained by the exact solution algorithm run by mathematical programming software. Finally, a numerical case is given to demonstrate how the proposed methods work. In the case, sensitivity analysis is adopted to reveal the effects of uncertainty on the routing optimization. Fuzzy simulation is then performed to help decision makers to select the best crisp route plan by determining the best confidence level shown in the fuzzy chance constraints.

Full textAbstract:
The transportation industry is the second largest industry of carbon emissions in the world, and the road transportation industry accounts for a large proportion of this in the global transportation industry. The carbon emissions of the road transportation industry in six Asia-Pacific countries (Australia, Canada, China, India, Russia, and the United States) accounts for more than 50% of this in the global transportation industry. Therefore, it is of great significance to study driving factors of carbon emissions of the road transportation industry in six Asia-Pacific countries for controlling global carbon emissions. In this paper, the Logarithmic Mean Divisia Index (LMDI) decomposition method is adopted to analyze driving factors on carbon emissions of the road transportation industry in six Asia-Pacific countries from 1990 to 2016. The results show that carbon emissions of the road transportation industry in these six Asia-Pacific countries was 2961.37 million tons in 2016, with an increase of 84.43% compared with those in 1990. The economic output effect and the population size effect have positive driving influences on carbon emissions of the road transportation industry, in which the economic output effect is still the most important driving factor. The energy intensity effect and the transportation intensity effect have different influences on driving carbon emissions of the road transportation industry for these six Asia-Pacific Countries. Furthermore, the carbon emissions coefficient effect has a relatively small influence. Hence, in order to effectively control carbon emissions of the road transportation industry in these six Asia-Pacific countries, it is necessary to control the impact of economic developments on the environment, to reduce energy intensity by promoting the conversion of road transportation to rail and water transportation, and to lower the carbon emissions coefficient by continuously improving vehicle emission standards and fuel quality.

Full textAbstract:
As an important part of urban public transportation systems, the feeder bus fills a service gap left by rail transit, effectively extending the range of rail transit’s service and solving the problem of short-distance travel and interchanges. By defining the potential demand of feeder bus services and considering its relationship with the traffic demands of corresponding staging areas, the distance between road and rail transit, and the repetition factor of road bus lines, this paper established a potential demand model of roads by opening feeder bus services and applying a logit model for passenger flow distribution. Based on a circular route model, a route starting and ending at urban rail transit stations was generated, and a genetic algorithm was then applied to solve it. The Wei-Fang community of Shanghai was selected as the test area. Per the model and algorithm, the feeder route length was conformed to a functional orientation of short-distance travel and the feeder service of a feeder bus; the route mostly covered where conventional bus lines were fewer, which is a finding that is in agreement with the actual situation; the feasibility of the model and algorithm was verified.

PurposeThis paper presents an overview of the recent development of Eurasian rail freight in the Belt and Road era and further evaluates its service quality in terms of transit times and transport costs compared to other transport modes in containerised supply chains between Europe and China.Design/methodology/approachA trade-off model of transit time and transport costs based on quantitative data from primary and secondary sources is developed to demonstrate the market niche for Eurasian rail freight vis-a-vis the more established modes of transport of sea, air and sea/air. In a scenario analysis, further cargo attributes influencing modal choice are employed to show for which cargo type Eurasian rail freight service is favourable from a shipper's point of view.FindingsAt present, Eurasian rail freight is about 80% less expensive than air freight with only half of the transit time of conventional sea freight. Our scenario analysis further suggests that for shipping time-sensitive goods with lower cargo value ranging from $US1.23/kg to $US10.89/kg as well as goods with lower time sensitivity and higher value in a range of $US2.46/kg to $US21.78/kg, total logistics costs of Eurasian rail freight service rail is cheaper than all other modes of transport.Practical implicationsAs an emerging competitive solution, Eurasian rail freight demonstrates to be an option beneficial in terms of transport cost, transit time, reliability and service availability, which offers a cost-efficient option enabling shippers to build up agile and more sustainable supply chains between China and Europe.Originality/valueOur study firstly provides a comprehensive assessment of present Eurasian rail freight including a thorough comparison with alternative modes of transport from a shipper's point of view.

Three main research questions are set, regarding: what organizational and cultural tools are used by companies within the intermodal rail and road industry; how these tools impact on security performance; and what environmental factors trigger the use of each tool. Design/methodology/approach In total, 13 companies within the intermodal rail and road industry have been studied in detail through in-depth case studies. Findings Results suggest that organizational and cultural tools impact positively on supply chain security, by reducing collusion and both operative and planning mistakes. In particular, such tools mitigate the effect of lack of cooperation and communication between partners and of inadequate partners. Practical implications Results point out that the ability of organizational and cultural tools to increase supply chain security has not been fully exploited yet. Tools to mitigate the negative effects on security of inadequacy of partners are not popular or they are not considered as powerful enough, despite it has been highlighted as the most relevant causal factor of lack of security.

Full textAbstract:
In the management of intermodal transportation, incentive contract design problem has significant impacts on the benefit of a multimodal transport operator (MTO). In this paper, we analyze a typical water-rail-road (WRR) intermodal transportation that is composed of three serial transportation stages: water, rail and road. In particular, the entire transportation process is planned, organized, and funded by an MTO that outsources the transportation task at each stage to independent carriers (subcontracts). Due to the variability of transportation conditions, the travel time of each transportation stage depending on the respective carrier’s effort level is unknown (asymmetric information) and characterized as an uncertain variable via the experts’ estimations. Considering the decentralized decision-making process, we interpret the incentive contract design problem for the WRR intermodal transportation as a Stackelberg game in which the risk-neutral MTO serves as the leader and the risk-averse carriers serve as the followers. Within the framework of uncertainty theory, we formulate an uncertain bi-level programming model for the incentive contract design problem under expectation and entropy decision criteria. Subsequently, we provide the analytical results of the proposed model and analyze the optimal time-based incentive contracts by developing a hybrid solution method which combines a decomposition approach and an iterative algorithm. Finally, we give a simulation example to investigate the impact of asymmetric information on the optimal time-based incentive contracts and to identify the value of information for WRR intermodal transportation.

Full textAbstract:
Saskatchewan Department of Highways and Transportation has been a leader in road and short-rail transportation initiatives that facilitate efficient commercial transportation to remote northern and rural areas. A recent initiative undertaken by Saskatchewan Department of Highways and Transportation is a public-private partnership with commercial carriers to allow larger truck configurations to haul primary weights on select secondary rural roads if the carrier deploys road friendly vehicle technologies, such as air-spring suspension and central tire inflation. The pilot partnership haul program has resulted in haul cost savings of between 20% and 50%, generating approximately four million dollars per year in total, which is subsequently shared between the carrier and Saskatchewan Department of Highways and Transportation. At the present time, equitable distribution of partnership haul cost savings and compliance audits are determined manually based on submitted logbooks and waybills. Because this manual system is labor intensive and prone to accounting errors, the administration of the partnership haul program is only tenable for larger carriers with semi-automated administration systems. As a result, a system that automatically allocates partnership haul cost savings and performs compliance audits is the enabling technology to expand the partnership program to small and mid-size carriers. International Road Dynamics Inc. proposed and developed an automated vehicle monitoring and audit system that is designed to facilitate the Saskatchewan partnership program. This paper discusses the Saskatchewan partnership program and describes the technological features and advantages of the automated vehicle monitoring and audit system. This paper also discusses other potential applications of the automated vehicle monitoring and audit system.Key words: commercial vehicle operations, automated vehicle monitoring system, central tire inflation, geographic information systems, global positioning systems, transportation sustainability, road preservation, intelligent transportation systems, rural road management.

Full textAbstract:
The study reports the CO2 emissions from diesel combustion in the following stages of the Brazilian ethanol supply chain: (a) agricultural operations (management), (b) sugarcane transportation to the mill, and (c) biofuel transportation to the destination. To assess the sensitivity of the results to different origins, five regions representative of ethanol production were selected, and the final destination was the port of Santos. The transportation stage from the mill to the port included the possible effects of using multimodal alternatives, such as road–rail and road–pipeline. The results indicate that diesel consumption varies greatly by region of origin, and agricultural management, such as tilling, planting, and harvesting operations, accounts for about 70% of total diesel emissions to the ethanol supply chain. Rail and pipeline transportation are ultimately important for mitigating emissions from fuel consumption in logistics corridors for exporting ethanol. It is a valuable contribution to supporting private actions and public policies related to the mitigation of emissions in the logistic stages of bioethanol, especially related to the optimization of the agricultural management process and improvement of the multimodal transport infrastructure, respectively. It is also a lesson to countries intending to produce ethanol from sugarcane.

Full textAbstract:
Demand uncertainty is an important issue that influences the strategic, tactical, and operational-level decision making in the transportation/logistics/supply chain planning. In this study, we explore the effect of demand uncertainty on the operational-level freight routing problem in the capacitated multimodal transportation network that consists of schedule-based rail transportation and time-flexible road transportation. Considering the imprecise characteristic of the demand, we adopt fuzzy set theory to model its uncertainty and use trapezoidal fuzzy numbers to represent the fuzzy demands. We set multiple transportation orders as the optimization object and employ soft time windows to reflect the customer requirement on on-time transportation. Under the above situation, we establish a fuzzy mixed integer nonlinear programming (FMINLP) model to formulate the capacitated road–rail multimodal routing problem with demand uncertainty and time windows. We first use the fuzzy expected value model and credibility measure based fuzzy chance-constrained programming to realize the defuzziness of the model and then adopt linearization technique to reformulate the crisp model to finally generate an equivalent mixed integer linear programming (MILP) model that can be solved by standard mathematical programming software. Finally, a numerical case is presented to demonstrate the feasibility of the proposed method. Sensitivity analysis and fuzzy simulation are combined to quantify the effect of demand uncertainty on the routing problem and also reveal some helpful insights and managerial implications.
