| 中文摘要 |
| 针对干道交叉口进口不同放行方式的实际需求, 利用绿波协调控制中的时距分析方法, 建立了通用干道双向绿波协调控制模型, 设计了基于控制模型的信号配时优化流程, 并利用混合整数线性规划方法实现了控制模型的优化求解. 模型算法将不受进口放行方式与路段行驶速度的限制, 能够遍历所有存在的最佳信号配时设计方案, 且易于通过计算机编程实现其优化求解. 算例分析表明, 利用通用干道双向绿波协调控制模型进行交通信号协调配时设计, 能够获得更为精确完整的最佳信号配时设计方案, 具有较强的科学合理性. |
| 英文摘要 |
| Considering the actual demand for different traffic released modes, we developed a general model of bidirectional green wave for the coordinate control of arterial road by using the method of time-space analysis. Signal timing optimization process based on the coordinate control model is designed, and the control model is solved by the method of mixed-integer linear programming(MILP). The algorithm is not constrained by either the traffic released mode or the link traffic speed; it finds out all possible optimal signal timing schemes by a simple computing programming. The example shows that the general model method can obtain optimal signal timing schemes more accurately and perfectly than the algebraic method. |
