BRT主动优先交叉口信号配时方法改进设计

现有的BRT主动优先控制配时,大多忽略红灯期间次干道排队长度过大,甚至溢出交叉口进道口范围的问题。据此建立优化模型如下:以交叉口乘客人均延误和次干道排队长度二者为约束组建双目标优化函数。最后,运用Synchro软件进行实例计算,结果表明此模型能有效降低次干道排队长度过大问题,优化交叉口的通行效率。

An Improved Signal Timing and Optimization Method of Intersections with the Idea of BRT Priority

This paper has points out the current problems in the signal timing design flow of intersections and proposes a new design method.Establish the optimal model as following: considers the passengers' precipitant delay in the intersection while considering the vehicle queue length of the sub-road.Finally,analysis an example by using Synchro based on this model,the results show that this method can eliminate the hidden trouble of the cars driving on the sub-road that spending too much time in a long queue,while...
