Optimization Model for Traffic Micro circulation Network Design

Abstract:

The idea of traffic microcirculation was proposed,and the bilevel programming model were constructed for the traffic microcirculation network design.The upperlevel problem was to minimize the total cost and adverse influence on environment and to maximize traffic efficiency under the constraints of saturation and reconstruction space of road links; the lowlevel problem adopted the user equilibrium traffic assignment to describe drivers’ route choice behaviors.With the efficacy coefficient method,an evaluation function of the multiobjective programming was found and the genetic algorithm for this model was proposed.A numerical example shows that the structure of the traffic microcirculation network and the capacity of each of the selected branch road can both be determined by solving the bilevel programming model.
