law of intra-urban movement Xiao Liang,∗ Jichang Zhao,† Li Dong,‡ and Ke Xu§ State Key Lab of Software Development Environment, Beihang University Abstract It is very important to understand urban mobility patterns because most trips are concentrated in urban areas.

walking being the oldest form of urban transport, and until the advent of major transformationsin transport technology in the nineteenth century, most cities were structured in ways that supported walkability.today, there is a change in transportation which emphasizes, the traditional pedestrian paths which are increasinglybecoming non-regulated spaces when compared to the urban spaces for auto...

This paper considers a time dependent(the travel time is not constant throughout the day) pollution routing problem (TDPRP), which aids the decision makers in minimizing travel time, toll cost and emitted pollution cost.  In complexity of urban areas most of the time one point is accessible from another with more than one edge. In contrast to previous TDPRP models, which are designed with only ...

Current situation in urban areas could be described by the cycle of urban decline. The choice of travelling by car produces more traffic jams, thus reducing the efficiency of public transport and the quality of live in urban districts by increasing pollution and accidents levels. Firms decide to move out to suburban areas where the provision of public transport is very low, and again people dec...

The vast majority of travel takes place within cities. Recently, new data has become available which allows for the discovery of urban mobility patterns which differ from established results about long distance travel. Specifically, the latest evidence increasingly points to exponential trip length distributions, contrary to the scaling laws observed on larger scales. In this paper, in order to...

Low density suburban development and excessive use of automobiles are associated with serious urban and environmental problems. These problems include traffic congestion, longer commuting times, high automobile dependency, air and water pollution, and increased depletion of natural resources. Master planned development suggests itself as a possible palliative for the ills of low density and hig...
