The embodiment of the invention provides an intersection signal lamp control effect analysis system and method, and the system comprises a parking frequency calculation module which is used for calculating the maximum parking frequency of a vehicle in a first direction of a target intersection in a previous signal lamp switching period at a current moment, a tracking detection device used for detecting the passing states of vehicles and pedestrians inside and outside the intersection of the target intersection at the current moment, a signal lamp detection module used for detecting control signals of signal lamps in all directions of the target intersection, and a signal lamp control effect analysis module used for judging whether the maximum parking frequency is smaller than or equal to afirst threshold value or not, and if so, analyzing the control effect of the signal lamp at the current moment according to the traffic conditions that the control signal of the target intersection at the current moment is green and the control signal is red. By implementing the method, the signal lamp control effect can be analyzed in real time, and the analysis result is more accurate.
本发明实施例提供了一种路口信号灯控制效果分析系统及方法,其中,该系统包括:停车次数计算模块,用于计算在当前时刻的上一信号灯切换周期内在目标路口的第一方向的车辆的最大停车次数;跟踪检测装置,用于检测当前时刻目标路口的路口内、路口外的车辆、行人的通行状态;信号灯检测模块,用于检测目标路口的各方向的信号灯的控制信号;信号灯控制效果分析模块,用于判断最大停车次数是否小于或等于第一阈值,若最大停车次数小于或等于第一阈值,则根据当前时刻目标路口的控制信号为绿灯的方向和控制信号为红灯的方向的通行状况分析信号灯当前时刻的控制效果。通过实施本发明可以对信号灯控制效果进行实时分析,分析结果更准确。
