摘　　要：假定出行者可选择道路公交和市域轨道交通快线2种出行方式,在分析乘客广义出行费用的基础上,建立市域轨道交通快线的快慢车开行方案双层规划模型,用以研究弹性需求下多方式交通路网中市域快线快慢车开行方案。采用遗传算法进行求解,并选取某中小型城市的市域轨道交通快线进行了算例验证。算例结果表明:早高峰时段以1:5的比例开行快慢车,选择市域快线出行的乘客量将增加16.71%,总运营效益将提高13.26%。It is assumed that passengers can choose 2 kinds of trip mode,either public transportation or urban rail transit express.Based on an analysis of passengers'generalized travel expenses,a two-level programming model of express and slow trains is established,in order to study the express and slow train operation schemes of urban express in multimodal traffic network under elastic demand.A genetic algorithm is used to solve the model,and the urban rail transit express of a middle-sized city is taken to verify the effectiveness of the proposed model.The calculation example shows that when the express and slow trains are operated at a ratio of 1:5 during the morning rush hours,the passenger volume of rail transit express will increase by 16.71%,and the total operating efficiency of the enterprise will increase by 13.26%.
