【摘要】 为了在保证路段行人过街安全与过街需求的前提下，同时提升路段车辆运行效率，充分考虑了车队离散到达与路段行人过街的动态影响，建立了路段行人过街感应式信号控制方法。首先，基于Robertson车队离散模型，以车头时距对上游到达车队进行动态划分，并根据路段行人过街点位预测下游车辆排队状态；以车队离散度选择下游到达车队中车辆作为信号优化输入参数建立感应控制方法，同时分析了路段行人过街位置对配时方案的影响；然后，通过SUMO软件的交通控制接口(traffic control interface, TraCI)搭建仿真环境，以车辆与行人的综合平均延误，分别对路段单向与双向交通环境的信号配时方案进行仿真验证与对比分析。结果表明，相比传统感应控制而言，优化后的感应控制在单向交通与双向交通情况下，行人与车辆综合平均延误分别降低5.56%、7.06%。更多还原

【Abstract】 To achieve the optimization goal of improving vehicle traffic efficiency on the premise of ensuring pedestrian crossing safety and crossing demand. Considering the dynamic influence of platoon dispersion and pedestrian crossing in road section, an inductive signal control method for pedestrian crossing in road section was established. Firstly, based on the Robertson platoon dispersion model, the downstream vehicle queue could be predicted with the position of pedestrian crossing, and the upstream platoon was dynamically divided by the headway. Based on the platoon dispersion, the vehicles in the downstream arrival platoon were selected as the signal optimization input parameters to establish the induction control method, and the influence of pedestrian crossing position on the timing scheme was analyzed. Then, the simulation verification and comparative evaluation were carried out through the TraCI(traffic control interface) of SUMO. The results show that compared with the ordinary induction control, in the case of one-way traffic and two-way traffic, the comprehensive average delay of pedestrians and vehicles is reduced by 5.56% and 7.06% respectively.更多还原
