Signal control decision model for adjacent intersection based on coordination rate
In view of traffic flow equilibrium of all entrance lanes, considering the coordinated demand of every phase, a new signal control decision model for adjacent intersections based on coordination rate is established. According to the relationship between traffic parameters in the theory of traffic flow continuity, the rationality of the parameter is analyzed and the definition and calculation formula of the phase coordination rate are presented, by taking phase split, vehicle queue length, traffic flow velocity at upstream section as input variables, and signal cycle and phase green light starting point as output variables. Applying the new method to the adjacent intersections signal timing optimization, Compared with the traditional signal timing method, the paper considers the bandwidth requirement in each phase, and deeply describes the coordination degree of intersection traffic flow, phases and adjacent intersections, which provided a new theoretical reference of signal parameter optimization for balanced traffic flow.
