混合收费站ETC与MTC车道通行能力研究

Research on the Traffic Capacity of ETC and MTC Lane in Composite Toll Station

基于对混合收费站交通流的分析,结合车头间距、制动过程及ETC车道折减系数的影响,确定ETC车道通行能力的计算方法。采用M/G/K排队论模型对MTC车道的通行能力进行分析,并确定混合收费站总通行能力的计算方法。建立Vissim仿真模型得到不同车道组合情况下的混合收费站通行能力仿真结果,对比仿真模型和理论模型并验证两者的吻合度。最后对6车道混合收费站进行仿真,得到在不同ETC使用率情况下的通行能力,提出了ETC车道最优的配置数量。研究确定了混合收费站通行能力的计算方法,并为配置ETC车道提供了参考依据。

Based on the analysis of the traffic flow of the composite toll station, the calculation method of the ETC lane capacity is determined by the influence of the head spacing, the braking process and the ETC lane reduction coefficient. The M/G/K queue theory model is used to analyze the MTC lane capacity and the calculation method of the total capacity of the composite toll station is determined. The Vissim simulation model is established to obtain the simulation results of the mixed toll station capacity under different lane combinations. The simulation model and theory model are compared and the coincidence degree is verified. Finally, the composite toll station of six lanes is simulated to obtain the traffic capacity under different ETC use ratio, and the optimal number of ETC lanes is proposed. The study determines the calculation method of the traffic capacity of the composite toll station and provides the reference for the configuration of the ETC lane.
