摘要
高速公路在改扩建作业过程中,必然对路段行车道有所侵占,形成分合流区段,而交通流发生紊乱往往就发生在分合流区段。本文以沪宁高速扩建无锡段桥梁施工为例,运用Vissim软件进行交通流微观仿真分析,对交通组织过程中最小施工路段间隔、中分带开口长度以及合流路段长度进行了研究,降低了因施工造成的对交通运行的影响。
The entension construcetion may result in the trowing lane occupation, and formed the merge and diver area, very often,the traffic turbulerne occurs such section.Taking Wuxi section of Huning Expressway extending engineering as example, this paper analyzed the minimal alternation of expending sectors, the minimal length of central divider opening and the length of merge section.
