Study of Transit Network Optimization Based on Microscopic Simulation

Abstract

The public transportation system is an integral part of the urban transport system and plays a positive role in promoting the city’s economic and cultural undertakings’ development. Therefore, it is necessary to establish the urban public transportation system in accordance with the scale of urban development and other modes of transport. This paper proposed a method of bus transit network optimization based on microscopic simulation software. Taking Lin He district of Bayannur as an example, according to the surveyed data, the paper uses the microscopic simulation software VISSIM to simulate and analyzed the current situation through the evaluation file of the software, then optimized the network. By analyzing the simulation results before and after optimization, we illustrate that after the transit network optimization, the buses’ average queue length decreases obviously, and the load factor of each section achieves a good level. Using microscopic traffic simulation software to simulate can intuitively and vividly reflect the optimization effect. It not only provides technical means for transit network optimization, but also provides important reference for mass transit network optimization and solving the problem of traffic congestion.
