摘要 为减少高速公路施工区由于车道封闭而形成的局部瓶颈路段,使得行驶车辆安全平稳通过施工区,在国内外高速公路施工区汇入控制策略研究的基础上,结合交通流理论对信号汇入控制进行分析和优化,并利用交通仿真技术对比分析常规汇入控制和信号汇入控制效果,研究发现信号汇入控制可以显著提高施工区单位时间的交通通过量,降低每辆车的平均延误和平均停车次数,为高速公路施工区管理控制提供参考和依据。 In order to reduce the bottleneck sections in the freeway work zone due to a partial lane closure and make a smooth and safety running of vehicles through the freeway work zone,based on the domestic and foreign study results of freeway work zone merge control strategy,the signal merge control was analyzed and optimized combined with traffic flow theory,and the effects between traditional merge control strategy and signal merge control strategy was contrasted by using traffic simulation.The results show that signal merge control strategy can significantly improve traffic volume per unit time and reduce average delay and average number of stops per vehicle in the work zone,which can be used to provide a reference for management and control for freeway work zone.
