Optimization and Simulation of Urban Multi-Mode Public Transport Network
The optimization of urban public transport networks is of great significance for improving urban travel efficiency and facilitating passenger travel.This article established an urban multi-mode public transport network based on the Space L modeling method,and defined the calculation method of node and arc impedance in the network.Considering the design rules of conventional bus routes as constraints,the mathematical programming model of the a-bove problems was constructed to maximize the overall efficiency of the multi-mode public transport network.Aiming at the combination explosion characteristic of the problem,the genetic-annealing algorithm was designed to solve it.Finally,the public transport network of Jinjiang District in Chengdu was selected for example analysis.The results show that the proposed method can effectively reduce the travel impedance between nodes of the public transport net-work and improve the overall efficiency of the public transport network.Moreover,a satisfactory solution could be ob-tained in a short time.
