Two-Objective Programming Model of Ring Road around Urban Agglomeration

  • A two-objective programming model was proposed to determine rational radii and service widths of urban ring roads.In the model,trip distance and general path impedance were taken as the two objectives.Three situations in terms of different OD pairs are considered in the trip distance function,and the model is solved with Dijkstra algorithm.The general path impedance function is expressed with a bi-level programming model of discrete traffic network with budget constraint,and the model is solved with branch and bound algorithm.The analysis results show that urban ring roads mainly serve the OD pairs with an angel less than 90 degree.The ring roads of Chengdu,the capital city of Sichuan Province,China,were taken as an example to show the feasibility of the proposed model.
