Analysis model on the loading capacity of freeways and expressways network in city area
摘要
Abstract
Considering the traffic share characteristics and traffic control features of freeways and expressways network in city area,a bi-level programming model was presented for the analysis on the loading capacity of the network. The upper level problem of the proposed model was how much additional traffic demand among city groups can be accommodated by the freeways and expressways network so that flow on each link was still within the given bound when the additional and existing external traffic was together assigned to the network. And the lower level problem of the model was a combined trip distribution/assignment model incorporating a destination attractiveness measure. The algorithm to solve the model was also studied and a numerical example was provided. It is indicated that the suggested model has a certain reference value in examining whether the freeways and expressways network is capable of accommodating future traffic growth, and in evaluating the structure performance of planning scheme for freeways and expressways network in city area.关键词
