Abstract Signal control of urban intersections still mainly employs single-point fixed phase, and optimal timing methods cannot optimize traffic given the altering state of traffic flow. To address these issues, the phase of optimal flow line combination is dynamically generated with the principle of traffic flow line compatibility and minimum loss of green light and according to the traffic flow at the intersection entrance. After ascertaining the combination of the periodic phase, the vehicles' average delay of traffic flow lines is analyzed when the vehicles are detained (or not detained) in the traffic flow line at the end of the period. Combined with the delay model, the optimal timing model, which can adapt to the dynamic changes in intersection traffic flow, is established. The optimal timing of phases is calculated to achieve dynamic optimization control of the intersection traffic line. The calculation example shows that the delay is small and the improvement of intersection running state is highly effective when the optimal timing model based on dynamic control of traffic flow is employed.
