摘　　要：为缓解城市轨道交通换乘站压力、提升轨道交通服务水平,以环线和半径线的组合形式为研究对象,以跨线直达乘客数最大、乘客总出行时间最短、车辆走行公里数最少为目标,考虑发车间隔、满载率、运用列车数等约束,构建环线和半径线之间的跨线列车开行方案规划模型,在分析环线特点的基础上进行客流分配,并设计包含OD客流路径分配的遗传算法进行求解。算例表明:与独立运营模式相比,环线与半径线之间采取跨线运营能够优化运力资源配置,大幅提升乘客直达性和服务水平。当目标函数权重系数比为3:1:1时,跨线客流需求中33.76%(1.10万人次)的乘客可避免换乘实现直达,乘客总出行时间缩短1.11%,车辆走行公里数减少1.05%。To alleviate the pressure on transfer station and enhance the service level of urban rail transport,the planning model for the cross-line operation scheme between the loop line and radial line was constructed by taking the combination of loop line and radial line as the research object.The objective was to maximize the number of direct passengers,minimize total passenger travel time and the distance traveled by trains.Taking into account constraints such as departure intervals,passenger load factors,and the number of trains,and considering passenger flow distribution based on the characteristics of the loop line,a genetic algorithm was designed that includes OD passenger flow distribution to solve the model.The case study shows that compared to independent operation,the cross-line operation between the loop line and radial line can optimize the allocation of capacity resources and improve passenger directness and service quality.When the coefficient weights of the objective function were set to a ratio of 3:1:1,33.76%(11,000 passengers) of the transfer passengers can avoid transfers and achieve direct travel,resulting in a1.11%reduction in total passenger travel time and a 1.05%reduction in distance traveled by trains.
