摘　　要：为研究高速公路改扩建施工区长度对路网运行效率的影响,依托S29滨莱高速改扩建工程,开展了VISSIM仿真实验,从规范和实验结果两个角度,具体分析了不同交通量和不同交通组织方式下的路网评价参数随施工区长度的变化规律,并结合仿真实验结果,从改扩建施工作业区上游转换区与过渡区上游的排队长度、平均延误时间、施工区速度平均值和平均停车次数角度分析,提出高速公路改扩建工程施工区长度的合理建议值。To investigate the impact of the construction zone length on the operational efficiency of the expressway network during expansion and reconstruction,this paper carried out the VISSIM simulation experiment based on the S29 Binlai Expressway reconstruction and expansion project,and analyzed the variation of the evaluation parameters of the road network with the length of the construction area from the perspectives of specifications and experimental results.Combined with the simulation experiment results,from the perspectives of the queue length,average delay time,average speed of the construction area and the average number of stops in the upstream conversion area and transition area of the reconstruction and expansion construction area,a reasonable suggested value of the length of the construction area of the expressway reconstruction and expansion project is proposed.
