Iterative transportation microsimulations adjust traveler route plans by iterating between a microsimulation and a route planner. At each iteration, the route planner adjusts individuals’ route choices based on the preceding microsimulations. Empirically, this process yields good results, but it is usually unclear when to stop the iterative process when modeling real-world traffic. This paper i...

In this work we propose a simulated annealing based search algorithm for optimal ramified or branched transportation route in R. The cost function of the transport network allows the system to merge small roads into larger highways, carry the goods together and separate them near the destination. As a result the transportation route has multiple branching-in and -out points, to some extent simi...

Transportation in economic systems such as services, production and distribution enjoys a special and important position and provides a significant portion of the country's gross domestic product. Improvements in transportation system mean improvements in the traveling routes and the elimination of unnecessary distances in any system. The Vehicle Routing Problem (VRP) is one of the practical co...

Transportation is basic service required by all citizens. Long route transportation is norm today for transporting goods and persons. Road transport has remained one of the important means of transportation. Increase in population and motorization in the country along with expansion of road network contributes to the number of road accidents, injuries and mortalities, as well as loss of product...

Hazardous materials traffic originates and terminates at numerous different locations throughout the North American railroad network. Rerouting of this traffic, especially Toxic Inhalation Hazard materials, away from populated areas has received considerable attention in recent years as a means of reducing risk. However, rerouting on a route specific basis is neither simple nor necessarily effe...

User equilibrium is a central concept for studying transportation networks, and one can view it as the result of a dynamical process of drivers’ route choice behavior. In this paper, based on a definition of O-D First-In-First-Out violation, we propose a new dynamical system model of the route choice behavior at the aggregate, route level for both static and dynamic transportation networks. An ...
