Structure Optimization Model of Comprehensive Transport Corridor Based on Resource Constraints

From the manager and the traveler's point of view, a bi-level programming model of structure optimization considering multi factors is proposed for comprehensive transportation corridor with parallel structure. In the higher level model, land resource consumption, upper model energy consumption and environmental emissions as indicators are selected as indexes to minimize the social resource cost. In the lower level model, the Mode-Path User Equilibrium model is selected for traffic distribution. To minimize the total travel cost of travelers, the supply and demand balance coefficient is selected as the channel response function and a model solution algorithm is designed based on genetic algorithm. At last, the proposed model is applied to Zhejiang Province Hangzhou Ningbo transportation corridor. The channel traffic demand is calculated for the planning year and the reasonable channel structure optimization program is given, which proves that the model is scientific and effective. (paper)
