在绿波协调控制交叉口群中,绿波段前沿交叉口对于交通流具有整流特性.针对单一交叉口延误计算方法对交叉口群整流特性考虑不足的问题,基于车流运行时间偏移呈正态分布的假设,采用非集计方法分别提出了绿波带内、绿波带间和右转车流的延误计算模型.分析了交叉口群对车流的整流作用,以最小二乘拟合法为基础,提出了交叉口进口道车辆到达函数拟合方法.分别考虑交叉口群绿波带内和绿波带间的车流运行时间偏移,以单车延误期望累积建立了交叉口进口道车流延误计算模型.利用交叉口车流数据验证了该方法的实用性和有效性.

英文摘要：

The rectification effects to traffic flow are observed clearly in the front part of signalized intersections under green wave coordinated control. But it is usually neglected when calculating the delay of single intersection. Based on the assumption that the running time deviation of traffic flow obeys normal distribution, the paper proposes three kinds of delay calculation models for internal of green wave band,interval of green wave band and right turn traffic flow by use of the disaggregate method. Considered the rectification characteristics of intersections, a vehicle arrival distribution function of entrance lane of intersection is presented based on least squares fitting method. A delay calculation method of traffic flow in the entrance lane of intersection is built through of the accumulation of each single vehicle expected delay with the influence of the running time deviation of traffic flow in the internal and interval of green wave band. At last, the practicability and effectiveness of the method presented is verified by a case study.
