摘要

In recent years, many urban traffic congestion has become increasingly serious in our country, the optimization of transportation network is causing more and more attention. And beijing-tianjin-hebei traffic pattern of integration has not yet formed, three traffic cooperation faces real obstacles. Therefore, this paper proposed construction and research of the multi objective optimization model of traffic integration in Beijing, Tianjin and Hebei. Firstly, Traffic network optimization model is established, from the traditional network planning model in network planning multi-objective optimization model is deduced, The improved model can reflect the reality better than traditional models. For transportation network reconstruction of beijing-tianjin-hebei region investment decision to provide the reference. Secondly, the improved hybrid parallel genetic algorithm is used to solve multi-objective network optimization model, namely the stability in multi-objective optimization is put forward under the framework of public transport network optimization model and its solution of multiobjective algorithm. Finally, the feasibility of the improved genetic algorithm is verified by numerical simulation.
