The invention provides a signal priority control method based on a condition without a bus lane, and the method comprises the steps: firstly, building an auxiliary line of a target vehicle delay isoline, and calculating the delay of a target vehicle and a probability density function of the target vehicle; secondly, determining the maximum queuing length in front of the target vehicle; then, calculating the delay expectation and variance of the intersection of the target vehicle based on the vehicle delay in the effective range and the corresponding probability density function; finally, appropriate signal control parameters are selected, signal control schemes are formed in the target period, target function values under all the schemes are calculated, and the signal control scheme with the minimum target function value is selected for implementation. According to the vehicle signal priority control method based on the condition without the bus lane, the defects that an existing method is based on the bus lane, queuing at an intersection is not considered, and the vehicle speed is regarded as a fixed value are overcome, the actual traffic condition is better met, and the vehicle signal priority control method is more accurate by considering the randomness of the vehicle running process. And the reliability and the feasibility of the control method are ensured.

    本发明提出一种基于无公交专用道条件下的信号优先控制方法,首先,建立“目标车辆延误等值线”辅助线,计算目标车辆延误及其概率密度函数;其次,确定目标车辆前方最大排队长度;然后,基于有效范围内的车辆延误及对应概率密度函数计算目标车辆交叉口延误期望和方差;最后,选取合适的信号控制参数,在目标周期内形成信号控制方案,计算各方案下的目标函数值,选取使目标函数值最小的信号控制方案进行实施。本发明提出的基于无公交专用道条件下的车辆信号优先控制方法,弥补了现有方法中基于公交专用道、不考虑交叉口排队、将车辆速度看作定值的不足之处,更符合实际交通情况,通过对车辆运行过程随机性的考虑,保证了控制方法的可靠性与可实施性。
