【摘要】：针对现有数解算法假定绿波设计速度固定取值的局限,提出了一种基于双向最大绿波带宽的通用数解算法.首先确定了相邻理想间距的取值空间.其次推导了上行、下行偏移绿信比的计算公式.再次,给出了理想绿灯中心线其上下方绿信比的计算公式.最后,以双向绿波带宽之和最大为优化目标,以上行、下行绿波设计速度与信号周期为优化变量,建立了最大绿波带宽优化模型.以实例验证文中通用数解算法的有效性.分析结果表明:文中通用数解算法能够突破上行、下行绿波设计速度固定取值的局限,能够更易于获得理想的绿波协调控制效果,具有较好的通用性与实用性.
[Abstract]:In view of the limitation of the existing numerical solution algorithm which assumes the fixed value of the green wave design speed, a general digital solution algorithm based on the bidirectional maximum green wave bandwidth is proposed. First, the value space of the adjacent ideal spacing is determined. Secondly, the calculation formula of green signal ratio of uplink and downlink is deduced. Thirdly, the calculation formula of the green letter ratio of the center line of ideal green light is given. Finally, the maximum sum of bidirectional green wave bandwidth is taken as the optimization objective, and the optimal model of the maximum green wave bandwidth is established in the above lines and the downlink green wave design speed and signal period as the optimization variables. An example is given to verify the effectiveness of the algorithm. The analysis results show that the algorithm can break through the limitation of the fixed design speed of uplink and downlink green wave, and can obtain the ideal coordinated control effect of green wave more easily, and has better generality and practicability.
