The invention discloses a method for predicting passing difficulty of a signal control intersection. The method comprises steps of obtaining the driving track of a vehicle at a signal control road section, and obtaining a travel distance of the complete green light time of the vehicle according to the driving track; obtaining the queuing length in a certain passing direction of the signal controlintersection, and obtaining a queuing length distribution diagram in a certain passing direction of the signal control intersection according to the time sequence; according to the queuing length distribution diagram, obtaining a maximum value and a minimum value of the queuing length in a certain passing direction at the next moment of the signal control intersection by adopting a difference method and a fitting method; and according to the maximum value and the minimum value of the queuing length in the certain passing direction at the next moment of the signal control intersection, the advancing distance of the complete green light time of the vehicle, the first parking time of the vehicle, the red light approximate time and the green light approximate time, obtaining the passing difficulty in the certain passing direction at the next moment of the signal control intersection. Through the method, traffic difficulty of the signal control intersection can be accurately predicted by utilizing the moving position data.
本发明公开了一种信控路口通行难易度的预测方法,包括:获取车辆在信控路段的行驶轨迹,根据行驶轨迹得到车辆完整绿灯时间的行进距离;获取信控路口某一通行方向上的排队长度,根据时间顺序得到信控路口某一通行方向上的排队长度分布图;根据排队长度分布图,采用差值法以及拟合法得到信控路口下一时刻某一通行方向上的排队长度的极大值和极小值;根据信控路口下一时刻某一通行方向上的排队长度的极大值和极小值、车辆完整绿灯时间的行进距离、车辆首次停车时间、红灯近似时间以及绿灯近似时间,得到信控路口下一时刻某一通行方向上的通行难易度。通过上述方法,可以利用移动位置数据,准确预测信控路口的通行难易度。
