摘　　要：将高速铁路运营速度提高至400km/h有利于提升旅行速度和旅客运输效率。但速度提高会影响追踪间隔,导致能力降低。在梳理高速铁路列车追踪间隔影响因素的基础上,构建了基于距离步长的高速铁路列车追踪运行多智能体仿真模型。通过仿真实验,计算了不同目标速度下的追踪间隔,并分析了各种追踪间隔随目标速度变化的趋势,以及出发及到达追踪间隔对列车牵引制动性能提升的响应情况。实验结果表明,在目标速度400km/h和采用中国标准动车组为基础模拟的牵引制动性能的仿真场景下,列车的区间追踪间隔在3min以内,而出发追踪间隔和到达追踪间隔均大于3min;若提升列车牵引加速度与制动减速度,则可以使列车出发及到达追踪间隔控制在3min以内。An increased speed of 400 km/h on high speed railway operation can bring faster travel and higher transport efficiency to passengers.However,increased speed affects train tracking intervals,reducing the capability.Based on clarifying the factors influencing train headways of high speed railways,a multi-agent simulation model of the high speed train tracking process based on spatial steps was constructed.Headways under different target running speeds were calculated by simulation experiments,and the change trends of train headways with target running speeds were analyzed.In addition,the response of departure and arrival headways to improved traction and braking performance of trains was explored.The experiment results show that in the scenario with a target running speed of 400 km/h and simulated based on China Standardized EMUs,the section headway is within 3 min while the departure and arrival headway exceed 3 min.It is possible to compress the departure and arrival headway to less than 3 min by improving the train traction acceleration and braking deceleration.
