High-speed police pursuits and the inherent risk of injury and death that can resuit constitute an important law enforcement and public safety issue. Police pursuits are dangerous. Available data indicate that the number of pursuits continues to increase, as well as the number of pursuit-related injuries and deaths. A traffic accident constitutes the most common terminating event in an urban pu...

car accidents are documented as a growing public health problem in iran as well as other developing countries. generally growing number of population and vehicles are not accompanied by extending road construction programs. these could be result in high death, disability, and economic loss in such country compare to develop one. this mainly affected young person who are economically more active...

In this article, we study transportation network in Minnesota. We show that the system is characterized by Taylor’s power law for fluctuation scaling with nontrivial values of the scaling exponent. We also show that the characteristic exponent does not unequivocally characterize a given road network, as it may differ within the same network if one takes into account location of observation poin...

The paper provides results for a non-standard, hyperbolic, 1-D, nonlinear traffic flow model on a bounded domain. The model consists of two firstorder PDEs with a dynamic boundary condition that involves the time derivative of the velocity. The proposed model has features that are important from a traffic-theoretic point of view: is completely anisotropic and information travels forward exactly...

Solving traffic equilibrium problem, or “traffic assignment”, as the last step in Transportation Planning, distributes OD trip demands of a transportation network over the network links with regard to Traffic Equilibrium Law, and estimates the link flows. In formulations of traffic equilibrium which are based on path saving, the memory consumption is considerably affected by the number of effct...

Empirical studies on the spatial structures in several real transport networks reveal that the distance distribution in these networks obeys power law. To discuss the influence of the power-law exponent on the network’s structure and function, a spatial network model is proposed. Based on a regular network and subject to a limited cost C, long range connections are added with power law distance...
