The invention provides a vehicle speed guide optimization method for avoiding a signal control intersection dilemma area, and aims at the potential dilemma area risk faced by a vehicle through a signal control intersection during a yellow light signal period, and maximizes the vehicle passing efficiency and smoothness on the basis of ensuring the avoidance of the dilemma area. The vehicle speed guiding optimization method comprises the steps of firstly judging whether vehicles fall into a dilemma area or not, and then aiming at all the vehicles falling into the dilemma area, taking maximum passing efficiency and smoothness as an optimization target, considering constraint conditions such as dilemma area avoidance, red light signals, safe time headway, safe headway, vehicle acceleration and speed and the like; and establishing a linear programming model for optimization. According to the method, multiple factors such as dilemma zone avoidance, vehicle passing efficiency, smoothness, a series of vehicle running constraints and the like can be synchronously optimized, so that the optimality of the generated guiding strategy is guaranteed, the vehicles can efficiently avoid the dilemma zone, and the running safety of the intersection is improved.

    本发明提供一种规避信号控制交叉口两难区的车速引导优化方法,针对车辆在黄灯信号期间通过信号控制交叉口所面临的潜在两难区风险,在保障规避两难区的基础上,最大化车辆通行效率和平顺性。该车速引导优化方法首先对车辆是否会落入两难区进行判断,然后针对落入两难区的所有车辆,以通行效率和平顺性最大作为优化目标,考虑了两难区规避、红灯信号、安全车头时距、安全车头空距、车辆加速度和速度等约束条件,建立线性规划模型进行优化。该方法能将两难区规避、车辆通行效率、平顺性、一系列车辆运行约束等多重因素进行同步优化,从而保障所生成引导策略的最优性,使车辆高效规避两难区提升交叉口运行安全。
