The economic, social and environmental benefits generated by the use of urban public transportation infrastructure constitute a complex dynamic urban public transportation infrastructure utilization benefit system. This paper evaluates the coupling coordination among these three benefits taking four Chinese autonomous municipalities as an example. These four cities have large-scale urban public...
This chapter is an introduction to the economics of the connection between urban transportation and land use. The nature of the transportation system strongly influences the patterns of land use in an urban area. Indeed, the long-run histories of urban areas sometimes are identified with the dominant mode of transportation of the time; the age of rail, the age of the automobile, and so on. Supp...
in this paper, we develop a freight transportation model for railway network considering hazmat transportation issue. in the transportation system considered, different customers can request for carrying hazmat and non- hazmat boxes. it is assumed that the sequence of the trains in the network is known. the objective is assigning the non-hazmat boxes and hazmat boxes to wagons of the trains so ...
The Greater Area of Munich is in the process of establishing a coordinated approach towards multi-modal, urban and interurban transportation management. Following the development and testing of several of the basic transportation management components, under the umbrella of previous R&D projects (Munich-COMFORT, TABASCO), system integration is entering the operational phase. The MOBINET transpo...
A city has a very complex transportation network. It is very hard for city planners to evaluate it in both micro scale and macro scale and so far most of these works have been done empirically. In this study a new method named Distributive Continuous Fractal Analysis will be introduced to evaluate the road networks. Previous researches treat a city as a whole and did fractal analyses between ci...

With the widespread advent of the smart phones equipping with Global Positioning System (GPS), a huge volume of users’ trajectory data was generated. To facilitate urban management and present appropriate services to users, studying these data was raised as a widespread research filed and has been developing since then. In this research, the transportation mode of users’ trajectories was identi...
This paper sets out to investigate whether the frequency distribution of the linear network circuits within a graph-based representation of a road transportation system can be helpful in identifying sprawl and, in particular, whether a ‘spatial signature of sprawl’ can be determined. This paper is based upon an earlier study on Peachtree City, Georgia and in particular of its dual transportatio...
Today, the occurrence or aggravation of harmful effects in urban transportation, such as air pollution and increased traffic accidents, reveals the necessity of sustainable transportation. In Rasht Metropolis with an annual growth rate of 1/9 percent in population, traffic is very severe. To better planning in the context of sustainable transport, first it is necessary to investigate the condit...
