摘　　要：乘客换乘时间需求是响应型接驳公交提供换乘服务时应考虑的一个重要因素。为此,提出一种考虑换乘时间需求的响应型接驳公交运行路径与调度协调优化方法。首先,将乘客按是否有特定换乘班次需求进行分类;然后,以同时接送模式下响应型接驳公交为研究对象,以乘客与运营商的效用加权之和最大为目标,以乘客换乘时间需求、乘客预约时间窗、车辆容量、车辆单程最大行程时间等为约束,构建发车间隔和运行路径一体化的协调优化模型,并基于遗传算法设计求解算法;最后,以长沙市地铁一号线尚双塘站周边区域为例进行实例分析。结果表明:与单接单送模式相比,同时接送模式系统的总效用提升了17.1%,同时接送模式的优越性显著;乘客换乘时间需求导致系统的总效用降低了9.42%,但考虑换乘时间需求提升了乘客的换乘效率,降低的系统总效用是可接受的;中小型车比较适合响应型接驳公交系统。The passengers'transfer time demand is an important factor that should be considered when responsive feeder transit provides transfer service.Therefore,a method to coordinate and optimize the operation paths and the dispatching of responsive feeder transit considering the transfer time demand was proposed.First,passengers was classified according to whether they had specific transfer schedules.Then,taking the responsive feeder transit under the simultaneous pickup and delivery mode as the research object,taking the sum of the utility weights of passengers and operators being maximal as the goal,and taking the passengers'transfer time demand,the passengers'appointment time window,the capacities of the vehicles,and the maximal one-way travel time of the vehicles as constraints,an integrated coordination optimization model for departure intervals and operation paths was established,and a solution algorithm based on genetic algorithm was designed.Finally,the area around Shangshuangtang Station of Changsha Metro Line 1 was taken as an example for the case analysis.The results show that compared with the single pickup and single delivery mode,the total system utility of the simultaneous pickup and delivery mode has increased by 17.1%,and it has significant advantages.The passengers'transfer time demand leads to the total system utility decreased by 9.42%,but the passengers'transfer efficiency is improved by considering the transfer time demand,so the reduced total system utility is acceptable.Medium and small vehicles are suitable for the responsive feeder transit system.
