【摘要】：为了均衡交通流向分布且保证控制方案平稳过渡,提出具有可变导向车道的交叉口时空资源优化模型以及可变导向车道标志与信号灯组协调控制方法。为验证本文模型与方法的有效性,借助数学软件MATLAB、交通仿真软件VISSIM及其信号控制逻辑工具VisVAP,使用一个算例对比分析可变导向车道控制方案与固定导向车道控制方案。结果表明:与固定导向车道控制方案相比,可变导向车道控制方案使具有可变导向车道的进口道及交叉口的车均延误分别降低3%~50%和7%~15%,说明可变导向车道控制优化模型能适应交叉口交通需求的潮汐特性,可变导向车道标志与信号灯组协调控制方法能保证交通流安全、平稳运行。
[Abstract]:In order to balance the distribution of traffic flow and ensure the smooth transition of the control scheme, the optimization model of intersection space-time resources with variable guide lane and the coordinated control method of variable guide lane sign and signal lamp group are proposed. In order to verify the effectiveness of the model and method, the variable guide lane control scheme and the fixed guide lane control scheme are compared and analyzed by using an example with the help of the mathematical software MATLAB, traffic simulation software VISSIM and its signal control logic tool VisVAP,. The results show that compared with the fixed guide lane control scheme, the variable guide lane control scheme reduces the vehicle delay of the entrance road with the variable guide lane and the intersection by 3% 鈮，
