摘要
交叉口设置行人专用相位避免人车冲突的同时增加了车辆延误.为分析有行人专用相位交叉口车辆的延误程度,在探讨常用交叉口车辆延误模型的基础上,通过采集相关数据,以HCM1985和Akcelik1988模型为依据,运用统计软件SPSS标定相关参数,建立了修正的有行人专用相位的车辆延误模型.基于威海市实际案例的分析结果表明,在饱和度较大的情况下。
Exclusive pedestrian phase set to avoid conflicts between pedestrians and vehicles at signalized intersections may increase vehicle delay.In order to find out the degree of vehicle delay at exclusive pedestrian phase intersections,the statistical software SPSS is used to calibrate parameters.The modified vehicle delay model is established in this paper by describing the existing delay models at intersections without exclusive pedestrian phase,collecting relevant data as well as referring to the model of HCM1985 and Akcelik1988.Finally,the research based on actual case of Weihai City,Shandong Province shows that the modified model fits better the actual delay compared to the reference model in the case of a larger saturation degree.
