Research on the Fine Grained Traffic Simulation Model and Standards for Tandem-arrangement Toll-booths Passageway
In order to study the impact of toll type,toll booth spacing,toll booth number and other conditions on the capacity of the duplex toll lane,a fine-grained traffic simulation model of the duplex toll lane is constructed,and the simulation accuracy of the capacity of the model is about 96％.Based on this model,the simulation analysis of the capacity of different setting conditions shows that the proportion of ETC vehicles in the traffic flow is negatively correlated with the capacity improvement of the mixed compound toll lane;The larger the proportion of large vehicles in the traffic flow,the greater the reduction of traffic capacity due to the insufficient spacing of toll booths,corresponding to 10％-50％of the proportion of large vehicle flow,and the reduction of traffic capacity of the double-booth and three-booth compound toll lanes reaches 2.53％-11.63％when the spacing of toll booths is insufficient;The range of capacity improvement of duplex toll lanes decreases with the increase of toll booths,and for toll lanes with long service time,the increase of duplex toll booths can bring more significant capacity improvement effect.
