摘　　要：针对现有数解法研究主要适用于单周期控制方式的不足,本文提出一种适于不等双周期的干道双向绿波协调控制数解法,通过重新定义双周期控制方式,打破了双周期交叉口信号周期时长固定为公共信号周期时长1/2的局限,并归纳了双周期交叉口的2种协调类型。本文算法首先通过计算干道的公共信号周期允许变化范围,为各交叉口选择合适的信号周期控制方式;其次,通过分析双周期交叉口的协调特点,推导出适用于双周期交叉口的理想交叉口间距计算公式;然后,通过设定双周期交叉口各相位绿信比的分配比,实现协调方向相位绿信比的分配;最后,以最大调整偏移绿信比之和最小为优化目标确定绿波协调控制方案。算例结果分析表明,与双周期模型法和单周期数解法相比,本文数解法求解方案的干道双向延误时间分别减少16.0%与19.6%,停车次数分别减少15.1%与15.5%,特别是本文数解法的求解方案能使支路车流和行人过街的平均延误时间较单周期数解法分别减少46.0%与50.7%。可见,本文数解法能够获得理想的绿波协调效果,扩大数解法的适用范围,在减少交叉口延误时间方面表现出明显优势。Considering the shortcomings of the existing algebraic method studies that were mainly applicable to singlecycle control, this paper proposed an algebraic method of bidirectional green wave of arterial road coordinate control for unequal double-cycle. By redefining the double-cycle control mode, the limitation that the signal cycle of a doublecycle intersection was fixed to half of the arterial public signal cycle was broken, and two types of coordination for double-cycle intersections were summarized. The signal cycle control mode for each intersection was determined by calculating the allowable range of the common signal cycle. Then, by analyzing the coordination characteristics of double-cycle intersections, the ideal intersection spacing equation for a double-cycle intersection was derived. The split allocation in the coordination direction was realized by setting the allocation ratio for each split of the double-cycle intersection. At last, the final optimization solution was determined by minimizing the sum of the maximum adjusted bias splits. The experimental results show that, compared with the double-cycle model and the single-cycle algebraic method, the proposed algebraic method reduces the average delay by 16.0% and 19.6%, and the average number of stops by 15.1% and 15.5%, respectively. In particular, the solution scheme of the proposed algebraic method can reduce the average delay of branch traffic and pedestrian crossing respectively by 46.0% and 50.7% compared to the singlecycle algebraic method. It proves that this method can achieve the desired green wave coordinated effect, extend the application of the algebraic method, and effectively reduce the delays.
