A general model of bidirectional green wave for coordinate control of arterial road and its optimization solution
通用干道双向绿波协调控制模型及其优化求解

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.
