面向网络效率的交通网络设计优化方法
Optimization method for the transportation network designbased on the network efficiency
摘要
Abstract
Based on the choice of the reasonable quantitative evaluation method for the transportation network efficiency with numerical example calculation and comparative analysis, this paper established a bi-level programming model for solving the transportation network design problem based on the network efficiency. Based on genetic algorithm and Frank-Wolfe algorithm, the method for solving the model was designed. The numerical example results show that, comparing with the optimization scheme with the objective of minimizing the system total impedance, the transportation network optimization scheme with the objective of maximizing network efficiency pays more attention to improve the current transportation network infrastructure utilization rates and guarantees the flow distribution in equilibrium. Therefore, this method can alleviate transportation network congestion with a smaller investment, and solve unbalanced distribution problems of road traffic flow and supersaturated problems of specific links efficiently.关键词
