摘要 针对新兴的"检测数据驱动"方法进行延误测定过程中在输入假设、模型建立及算法容错性方面存在的典型问题,提出了基于两个检测截面交通参数的"总体抽样"动态延误测定方法.以每个信号周期为计算单元,研究了周期划分方法,车辆在"离去检测器"的首车到达时间、尾车驶离时间测定方法,"进入检测器"的进入时间上下限阈值确定方法以及相应的车辆引道延误计算方法.最后以上海市曹安公路-祁连山南路和武宁路-大渡河路两个交叉口直行车道组的引道延误动态测定为例,以人工实测的37个周期1 565辆车的引道延误数据为基础,验证了"总体抽样法"的精度.结果表明,在检测器精度为100%时,"总体抽样法"测算延误的绝对差为4.1s,95%的检测精度下绝对差仅减少0.1s.该方法对检测误差不敏感,可用于向信号控制系统提供准确、及时、可靠的延误指标. The typical problems of emerging methods based on detector data for measuring delay at urban signalized intersections such as input hypothesis, model establishment and fault-tolerance performance were pointed out. A new method named "sampling population" which used two rows of detectors for dynamic survey of approach delay by the signal cycle at unsaturated intersections was put forward, including the process of cycle split, the arrival time of the first car and the departure time of the last car at exit detectors, the upper and lower boundary of input gap at entrance detectors, and corresponding method for approach delay measuring. Finally,two case studies were made in Shanghai (Caoan-Qilianshan intersection and Wuning-Daduhe intersection, including 37 cycles and I 565 vehicles) to verify the accuracy of the proposed method. The results show that mean absolute error (MAE) of the measurement delay is 4.1 seconds under no detector error compared to 0. 1 seconds fewer than 95% detector accuracy. The method is insensitive to the detector error, and can be used to provide the accurate, timely and reliable delay index for traffic control system.
