摘　　要：针对交叉口延误过大制约着快速公交系统的发展问题,基于车路协同技术,通过预测BRT车辆行程时间并确定到达时间窗在信号周期中的定位,以交叉口总体人均效益最大化为目标,兼顾乘客乘坐舒适性、车辆运行状态、社会车辆交通效益等因素提出了绿灯延长、红灯早断和相位插入等3种BRT单点交叉口信号实时优先控制方法.最后以济南市BRT一号线北园大街无影山路交叉口为背景,基于VISSIM仿真软件进行信号优先控制方案的验证,结果显示:该方案可以使交叉口人均延误平均降低18.60%,BRT车辆运行速度平均提升7.28%.As a high efficiency and low-cost public transport, the Bus Rapid Transit system has been recognized as an effective means of solving urban transport problems. However,more and more delays at signalized intersections restricted the development of B R T . Based on the Vehicle Infrastructure Integration,this paper has researched the model of signal priority of BRT with green extension, red reduction and phase insertion in isolated intersection. Th e model is based on the prediction of the travel time and arriving time window of BRT . The objective is to maximize passenger benefit, with the consideration of BRT running status, ride comfort, background vehicle benefit, among others. At last, this paper selects a typical intersection of Jinan BRT Line One to do simulation experiments using VISSIM. According to the result,this model can reduce the average passenger delay by 18. 60 percent and improve the average travel speed of BRT by 7. 28 percent.
