摘要 为了使交通更加高效便利,该文针对行人过街交通信号配时问题,提出了以考虑行人等候时间和行人数量来决定信号灯的变化方案。该文基于背景差分行人检测算法,检测行人数量并统计行人的等候时长,建立了依据等候行人数和等候时长的信号配时方案,并在Matlab中验证了算法的有效性。最后利用VISSIM对实际交通路口进行配时仿真,并分析了车辆和行人的等待时间和延误时间,以此来提高车辆和行人的出行效率。 In order to make transportation more efficient and convenient,this paper proposes to determine the change of the signal light by considering the pedestrian waiting time and the number of pedestrians in order to solve the problem of pedestrian crossing traffic signal timing. Based on the background differential pedestrian detection algorithm,this paper detects pedestrians and counts the waiting time of pedestrians,and establishes a signal timing scheme based on the number of waiting lines and waiting time. The effectiveness of the algorithm is verified in Matlab. Finally,VISSIM is used to simulate the actual traffic intersection,and the waiting time and delay time of vehicles and pedestrians are analyzed to improve the efficiency of vehicles and pedestrians.
