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 caused by the lane closure in the expressway construction area, the traveling vehicles can pass the construction area safely and steadily. Based on the research on the control strategy of the expressway construction area both at home and abroad and the traffic flow theory, The analysis and optimization of traffic flow control and traffic simulation are used to compare and analyze the control effects of conventional inbound control and signal inbound control. It is found that the control of signal input can significantly improve the traffic throughput per unit time in the construction area and reduce the average delay and average of each vehicle Parking frequency, for highway construction area management control to provide a reference and basis.
