运用计算机仿真技术结合实际交通量数据与OD出行矩阵提出了公路改扩建交通组织实施方案。以佛开高速公路扩建为依托,阐明了公路改扩建大型路网的VISSIM建模技术与交通组织实施方案,即借助于OD矩阵,运用动态分配方法,通过控制交通瓶颈路段的排队长度,使整个路网的运行效率达到最优。 Using computer simulation technology combined with the actual traffic data and OD travel matrix proposed highway reconstruction and expansion of traffic organization implementation plan. Based on the expansion of the Fokai Expressway, the VISSIM modeling technology and traffic organization implementation plan for large-scale road network reconstruction and expansion are set forth. By means of OD matrix and dynamic allocation method, the queuing length of traffic bottlenecks is controlled so that the whole Road network to achieve the best operating efficiency.
