摘　　要：以轨道与常规公交一体化网络为研究对象,以一体化网络性能优化为研究目标,提出基于轨道交通新线的常规公交网络优化调整方法。首先在分析问题的基础上提出常规公交候选线路的生成算法,然后以公交网络有效服务及轨道交通客运量最大、乘客平均公交成本最小、运营成本最低、车辆需求最少为目标,构建常规公交网络优化调整的多目标规划模型。模型不仅优化调整常规公交线路的走向,而且优化调整线路的运营参数。然后设计遗传算法以求解模型的Pareto解集,最后用实例对模型与算法进行验证。With the integrated network of rail transit and bus network as the subject of study and optimization of performance of the integrated network as the objective of study, the methodology was proposed for bus net work optimization and adjustment based on new rail transit lines. Analyzing the problems to face, the heuristic algorithm for generating bus candidate lines was investigated. Then, setting maximizing the bus passenger traffic volume and rail passenger traffic volume and minimizing the average bus passenger travelling costs, bus operating costs and number of buses in demand as the objectives,the multi objective programming model for bus network optimization and adjustment was built. The genetic algorithm was developed to get thePareto so lution set of the proposed model. A real example was used to verify the proposed mathematical model and the solving algorithm.
