In order to analyze the effectiveness of setting exclusive pedestrian phase (EPP) under different vehicle yielding rates, the effect of EPPs on traffic efficiency is studied and a setting condition of EPP considering pedestrian-vehicle interaction is proposed in this paper. First, the main factors influencing the behavior of vehicles and pedestrians during pedestrian-vehicle interaction are analyzed, and a pedestrian-vehicle interaction (PVI) model at the crosswalk of urban road is established. Second, assuming that vehicle arrival obeys the Poisson distribution, the delay models of vehicle passengers and pedestrians crossing the street at the intersection are established, and taking the total delay of traffic participants as the main index, the setting condition of EPP are proposed. Third, based on the video of pedestrian-vehicle interaction at crosswalks, the parameters of the proposed model are calibrated. Through sensitivity analysis, the change of the total delay of traffic participants is analyzed under different conditions of pedestrian and vehicle arrival rates. Finally, by introducing pedestrian-vehicle interaction rules, a cellular automata (CA) simulation platform of pedestrian-vehicle interaction in crosswalk is established; based on the field data of Shanghai, a simulation model of intersection is established, and the total delay, queue length, and vehicle throughput under conventional signal control plan and EPP plan are compared. The results show that the pedestrian-vehicle interaction process has a great influence on the total delay of traffic participants at intersections, and pedestrian-vehicle interaction should be considered in the setting conditions of EPP. Under the same condition of vehicular flow, the more the pedestrian flow is, the smaller the delay increment will be. The higher the vehicle yielding rate is, the smaller the delay increment will be after setting EPP.

考虑行人与车辆相互作用的两阶段信号交叉口设置专用行人相位的条件

为了分析在不同车辆良率下设置专用人行道相位（EPP）的有效性，研究了EPP对行车效率的影响，提出了一种考虑行人与车辆相互作用的EPP的设定条件。首先，分析了在行人互动过程中影响车辆和行人行为的主要因素，建立了城市道路人行横道上的行人互动模型。其次，假设车辆到达遵循泊松分布，建立交叉路口过马路的车辆乘客和行人的延误模型，并以交通参与者的总延误为主要指标，提出了EPP的设置条件。第三，基于人行横道上行人与车辆互动的视频，对提出的模型的参数进行了校准。通过敏感性分析，分析了行人和车辆到达率不同条件下交通参与者总延误的变化。最后，通过引入人机交互规则，建立了人行横道中人机交互的元胞自动机（CA）仿真平台。基于上海的现场数据，建立了交叉口的仿真模型，比较了传统信号控制方案和EPP方案下的总延误，排队长度和车辆通过量。结果表明，行人与车辆的交互过程对交叉路口交通参与者的总延误有很大影响，在EPP的设置条件下，应考虑行人与车辆的相互作用。在相同的车辆流量条件下，行人流量越多，延迟增量越小。车辆屈服率越高，设置EPP后的延迟增量越小。
