The idea of traffic microcirculation was proposed,and the bilevel programming model were constructed for the traffic microcirculation network design.The upperlevel 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 lowlevel problem adopted the user equilibrium traffic assignment to describe drivers’ route choice behaviors.With the efficacy coefficient method,an evaluation function of the multiobjective programming was found and the genetic algorithm for this model was proposed.A numerical example shows that the structure of the traffic microcirculation network and the capacity of each of the selected branch road can both be determined by solving the bilevel programming model.
