摘要 针对相邻较近的交织区车辆持续交织运行特点,以提高交织区通行效率及交通安全为目标,提出一种基于变道约束下近邻交织区交通均衡组织方法,旨在计算不同时段交通量所对应近邻各交织区的最佳提前变道诱导距离,以减少近邻交织区车辆相互干扰,降低平均交通延误,提高道路通行效率.对重庆市海峡路两段近邻交织区的日均交通量(4 092 pcu/h),早高峰时段交通量(5 340 pcu/h),晚高峰时段交通量(4 596 pcu/h),以及年均交通量(3 276 pcu/h)进行仿真建模分析.实验选取近邻交织区内累计平均延误作为近邻交织区的评价指标,利用仿真软件(Vissim 4.3)持续仿真40次.结果表明,最佳提前变道约束距离为交织区长度的60%,其相应的平均交通延误分别降低了57%、73%、63%和72%. Aiming at improving the traffic efficiency and safety in the weaving sections,a traffic equilibrium organization method for neighbor weaving sections based on lane-changing constraints is proposed to calculate the optimal early lane-changing distance of the neighbor weaving sections corresponding to traffic volume in different periods,so as to reduce the mutual interference of vehicles in the neighbor weaving sections and reduce the traffic volume.The simulation models of daily average traffic volume(4 092 pcu/h),early peak traffic volume(5 340 pcu/h),late peak traffic volume(4 596 pcu/h)and annual average traffic volume(3 276 pcu/h)in three continuous weaving sectionss of Chongqing Strait Road were analyzed.The multi-objective cumulative average delay in the neighbor weaving sections is selected as the evaluation index of the neighbor weaving sections.The results of 40 continuous simulations with Vissim 4.3 show that the optimal distance of advance lane change constraint is 60%of the length of interlaced zone,and the corresponding average traffic delay is reduced by 57%,73%,63%and 72%respectively.
