考虑相邻交叉口的公交优先信号模型与仿真
|
摘要
在公交系统优先信号模型优化设计中,传统公交信号优先仅考虑公交车辆通过交叉口的影响,而忽视了相邻交叉口所受的影响,因此考虑相邻交叉口通行能力的影响,以总交叉口人均延误为目标,提出以公交优先度作为判别是否优先以及优先程度的决策依据,进而采用绿灯延长和红灯早断两种策略,建立有限的主动优先控制模型。最后,通过VISSIM软件的VAP模块建立仿真模型,并通过案例分析,与无公交优先策略、绝对公交优先策略进行对比分析,结果表明与无公交优先策略相比,所提出的优化控制策略,在中高饱和度下能使总交叉口人均延误平均降低15.7%,在高饱和度下平均降低14.6%。验证了研究成果具有应用价值。
Traditional transit signal priority methods only consider the impact of one intersection the bus going through,and ignore the impact of neighboring intersections. This paper considers the impact of neighboring intersections to minimize average delay of passengers in all intersections. The transit priority degree is used to distinguish whether the priority and how much of priority can be given. Then a limited active signal priority control model is established by adopting green phase extension or red phase truncation. Simulation is conducted by VAP module in Vissim. Simulation results indicate that,comparing to non- priority strategy,the proposed optimal control strategy in this paper can reduce the average passenger delay by an average 15. 7% in middle high- volume,and an average14. 6% in high- volume.
