The invention relates to a signal time sequence control method for a signal control intersection. The method comprises the following steps of acquiring effective data of a target signal control intersection; establishing a safety cost-efficiency cost model related to an exclusive pedestrian phase (EPP) or a two-way crossing (TWC) by utilizing effective data; constructing a target function by taking the minimum total cost of the efficiency and safety of the signal control intersection as a target, and solving the safety cost-efficiency cost model to obtain a signal time sequence of the signal control intersection; and performing signal control intersection control by using the signal time sequence of the signal control intersection. Compared with the prior art, the method has the advantagesthat the influence of TWC and EPP on traffic safety and efficiency is integrated into one economic evaluation model, a more accurate signal time sequence can be obtained, and therefore accurate signal control intersection control is achieved.
本发明涉及一种信控交叉口信号时序控制方法,包括:获取目标信控交叉口的有效数据;利用有效数据建立与专属行人相位(exclusive pedestrian phase,EPP)或双向通行相位(two‑way crossing,TWC)有关的安全成本‑效率成本模型;以信控交叉口效率安全总成本最小为目标构建目标函数,求解安全成本‑效率成本模型,得到信控交叉口信号时序;利用信控交叉口信号时序进行信控交叉口控制。与现有技术相比,将TWC和EPP对交通安全和效率的影响整合到一个经济评估模型中,可以得到更精确的信号时序,从而实现精确的信控交叉口控制。
