Abstract: In order to accurately describe the disruption of pedestrian crossing facilities and how this affects vehicle delay at non-signalized segments of urban roads,vehicle yield modes for pedestrians and an empirical probability model were proposed,and finally a comprehensive vehicle delay model was established based on the distribution of crossing pedestrians.The results show that the distribution of crossing pedestrians has a significant influence on the selective probability of vehicle collision avoidance modes,and the vehicle delay error is in a reasonable range between the theoretical model calculation and the actual survey case.This shows that the constructed method is effective.

摘要: 为了准确描述城市道路无信号控制路段行人过街设施对机动车延误的干扰,提出了路段人车冲突机动车避让方式、经验概率分布及基于过街行人数量分布的机动车综合延误计算模型。研究表明:一次行人过街数量分布对机动车选择避让方式概率具有重要影响,该模型计算的理论机动车延误与实际案例机动车延误误差处于合理范围内,表明该经验方法是有效的。
