摘要
我国城市道路交叉口中大量行人与机动车冲突导致了交叉口运行效率降低,同时也引发了不容忽视的安全问题。在对无信号控制交叉口进行录像调查的基础上,分析了行人与机动车冲突特性,利用实测数据建立了行人过街间隙选择行为概率与安全间隙之间的数学关系模型,并对模型进行了检验与验证,证明该模型具有较好的拟和度和预测精度,同时与已有的Logit模型进行比较分析。
The conflicts between crowed pedestrians and vehicles greatly decrease the capacity of intersection,and lead to safety problems.This paper analyzes the characteristics of pedestrian-vehicle conflicts based on the video surveys.The cubic polynomial function is used to model the relationship between the probability of pedestrian choice behaviors and safety margins by using the measured data.The model is calibrated and validated.At last,this model is compared with the existing binary Logit approach.
