摘　　要：立足综合运输,考虑高铁的速度优势和接驳车辆的机动灵活特点,建立高铁旅客出行需求灵活接驳运输模式。基于交通网络的动态性及乘客需求的定制性和动态性,以乘客成本、接驳巴士运营成本及乘客等待时间成本为目标,建立高铁站定制性灵活线路接驳巴士路径优化模型,并将该模型分为预排班和实时需求2个子模型。根据该模型的特点,采用改进的蚁群算法求解模型,并构造了一个虚拟的交通网络,验证了该模型及其算法的有效性。Based on comprehensive transportation,full consideration is given to the speed advantage of high-speed rail and the flexible features of connected vehicles to establish a flexible connection mode for high-speed passengers to travel.Based on the dynamic nature of traffic networks,and the customization and dynamics of the passenger demand,with the goal of passenger costs,operating costs of feeder buses and passenger waiting time costs,a customized flexible route feeder bus route optimization model for high-speed rail stations has been established.It is divided into two sub-models:Pre-arrangement model and real-time demand.According to the characteristics of the model,an improved ant colony algorithm is used to solve the model.A virtual traffic network was constructed to verify the validity of the model and the algorithm.
