Research on the optimal model of public transport route generation for connecting urban rail transit

Abstract

The operation of urban rail transit will surely have effect on the original conventional bus system. To realize the development system of “Integration of the two networks, coexistence and common growth” between the rail transit and the conventional bus lines, this article aims to further optimize the layout of the conventional bus lines in connection with the urban rail transit. First of all, this paper analyzes the connection between the original conventional bus stations and the existed rail transit stations, and determines the generating steps of the candidate lines on this basis. Later, this article constructs an optimization model for bus network connected to rail transit, and tries to improve the traditional genetic algorithm by introducing simulated annealing operator. Finally, this article takes Xiguan Cross Station of Lanzhou Rail Transit Line 1 as the example, and applies the improved genetic algorithm to clarify the example, which is meant to verify the effectiveness of the algorithm and to provide the reference for the development of public transportation in Lanzhou City.
