摘　　要：在高密度城市地区,行人对道路通行能力有很大影响。研究了新交规下行人对路段通行能力的影响,提出了考虑人车交互的路段无控制人行横道的道路通行能力模型(UC-PVI)。基于logit模型和非完全信息静态博弈论建立了考虑多种影响因素的人车交互(PVI)模型。通过该模型可以得到人行横道处6种人车交互情形的概率。基于停车线法的基本思想和上述各情形的概率建立了UC-PVI模型,并对影响模型的主要因素进行了灵敏度分析。建立了人行横道处人车交互元胞自动机仿真平台,并将仿真结果与通行能力模型的计算结果进行比较。结果表明,微观仿真和UC-PVI模型的相对误差总体小于16%,验证了模型的有效性。本研究为更准确的估计行人影响下的交叉口通行能力提供了借鉴。In high density urban area, pedestrians have a great impact on road capacity. The influence of pedestrians on road capacity is studied, and a road capacity model at uncontrolled crosswalk considering pedestrian-vehicle interaction is proposed. Based on logit model and static game theory of incomplete information, a pedestrian-vehicle interaction model is established. Through this model, the probability of six kinds of pedestrian-vehicle interaction situations can be obtained. Based on the basic idea of the stop line method and the probabilities of the above-mentioned situations, the capacity model considering pedestrian-vehicle interaction is established, and the sensitivity analysis of the main factors affecting the model is carried out. The simulation platform of pedestrian-vehicle interaction based on cellular automata is established, and the simulation results are compared with the calculation results of the capacity model. The results show that the relative error of the two models is less than 16%, which proves the validity of the model. This study provides a reference for more accurate estimation of the intersection capacity under the influence of pedestrians.
