【摘要】：为保证救护车、消防车等紧急车辆安全、高效率地完成应急救援任务,基于车路协同系统(CVIS),综合利用交通信号协调配时与车速引导,提出紧急车辆在交叉口的改进型优先通行控制方法。利用VISSIM与Visual Studio 2008搭建的联合仿真试验平台进行模拟试验,对比分析仿真环境中不同控制方法下紧急车辆通过交叉口的实际运行数据。结果表明,相比于传统优先通行控制方法与定周期控制方法,采用改进型优先通行控制方法,可使紧急车辆在交叉口的平均行程时间分别减少19%与32%,平均速度分别提高18%与37%,平均排队长度分别减少66%与84%,停车次数、平均停车次数也显著减少。
[Abstract]:In order to ensure the safety of emergency vehicles, such as ambulances, fire engines and other emergency vehicles, the emergency rescue mission is accomplished efficiently. Based on the vehicle-road coordination system (CVIS), traffic signals are used to coordinate timing and speed guidance. An improved priority traffic control method for emergency vehicles at intersections is proposed. The simulation test is carried out by using the joint simulation test platform built by Visual Studio 2008 and Visual SIM, and the actual operation data of emergency vehicles passing through the intersection under different control methods in the simulation environment are compared and analyzed. The results show that, compared with the traditional priority traffic control method and the fixed period control method, the improved priority traffic control method is adopted. It can reduce the average travel time of emergency vehicles at the intersection by 19% and 32%, increase the average speed by 18% and 37%, reduce the average queue length by 66% and 84%, and decrease the number of stops and the times of stopping significantly.
