摘要 为研究协调相位中绿灯不同协调位置对绿波带控制效果的影响,提出一种考虑绿灯协调位置的双向绿波协调控制算法。该算法考虑交叉口相位组成、相位顺序等因素,通过调整协调相位绿灯协调位置的方式,推导出协调相位绿灯起止时刻计算公式,以车均延误及停车次数最小为目标,完成干线绿波带的方案设计。通过算例对比分析绿灯协调位置,分别为0%、25%、50%、75%、100%时的延误和停车次数,以此来分析不同协调位置所对应绿波带方案的控制效果。算例分析结果表明,随着绿灯协调位置的改变,各绿波带控制方案的控制效果存在一定差异,在本算例中,协调位置在100%时车均延误及停车次数最小。该研究对优化绿波带控制效果、提高干线服务水平具有现实意义。 In order to study the influence of different coordination positions of the green time in the coordination phase on the control effect of the green wave band,this paper proposes a two-way green wave coordination control algorithm that considers the coordination position of the green time.This algorithm takes into account the phase composition and phase sequence of the intersection,and adjusts the coordinated phase green time coordinate position to deriving the formula for calculating the start and end time of the coordinated green time.The goal is to minimize the average delay of vehicles and the number of stops design.The comparison and analysis of the green time coordinated positions at 0%,25%,50%,75%,and 100%of the delay and the number of parking times are compared through examples to analyze the control effect of the green wave zone schemes corresponding to different coordinated positions.The analysis result of the examples shows that with the change of the coordinated position of the green time,the control effect of each green wave band control scheme is different.In this example,the vehicle delay and the number of stops are minimized when the coordinated position is 100%.It can be seen that this study has practical significance for optimizing the control effect of the green wave band and improving the service level of the main line.
