摘要: 现有干道协调控制方法主要是追求更大绿波带宽,但是由此产生的附加红波带对协调控制效果的影响没有引起足够的重视。为此,本文建立基于交叉口混合放行的干线红波带宽最小化优化模型。模型以干线直行路径及左转路径红波带宽占周期比值加权之和最小为目标函数,采用NEMA(National Electrical Manufacturers Association)双环相位和单独放行相位两种放行方式,并给出两种放行方式统一的内部相位差线性计算公式。任意交叉口均可指定放行方式,亦可自由选择。该模型采用整数线性规划方法,确保获得最优解。以苏州市松陵大道的5个连续交叉口实例进行分析。结果表明:相较于Multiband、Pband和All-direction优化方案,本文模型有效减少了干线直行和左转车辆平均延误时间与停车次数,取得较优的干线绿波协调控制效果。

Abstract: Existing arterial coordination control methods primarily focus on maximizing the green wave bandwidth to facilitate the continuous flow of traffic. However, the potential impact of the additional red wave bands resulting from this expansion in the coordination control effectiveness has not received adequate attention. To address this issue, this paper establishes an optimization model for minimizing the red wave bandwidth on arterials based on mixed release strategies at intersections. The model minimizes the weighted sum of the ratios of red wave bandwidth for through and left-turn movements to the cycle length, and adopts both the NEMAdouble-ring phase and split phase release strategies, and provides a unified linear calculation formula for the internal phase difference for both release methods. Intersections can be specified to use the release method or choose freely. The model is developed by integer linear programming for the optimal solution. An analysis was conducted using five consecutive intersections on Songling Avenue in Suzhou as a case study. The results indicate that, compared to the Multiband, Pband, and All-direction optimization schemes, the model proposed in this paper effectively reduces the average delay time and stop occurrences for through and left-turn vehicles on arterial corridors. The proposed model can achieve better control of the corridor progression coordination.
