针对超限检测站称重检测引起的交通拥堵问题,深入研究多车型自适应超载控制技术。基于排队论理论对超限检测站内车辆排队模型进行分析,并确定自适应超载控制技术模型的启动条件。运用VISSIM软件对自适应超载控制技术模型启动值进行标定并对超限检测站运行情况进行仿真。结果表明:标定启动值的模型可使超限检测站的超载控制率提高约10.2%,正常载重的货车延误降低约25.8%,超载货车的延误降低约34.3%。
In view of the traffic jams and congestion caused by weight detection of the weigh station,the multitype vehicle adaptive overload control technology is researched deeply. The vehicular queueing model of overload detection station and the starting conditions of the model of adaptive overload control technology is determined based on the queue theory. Starting value of the model is calibrated and the operation status of the weigh station is simulated with VISSIM. The results indicate that the model calibrated starting value increased the capture rate of weigh stations by about 10. 2%,decreased the delay of non-overload trucks by about 25. 8% and reduced the delay of overload trucks by about 34. 3%.
