The invention discloses a vehicle red light running prediction method under a vehicle-road cooperation condition. Based on vehicle GPS position information, speed information, intersection stop line position information, signal lamp phase and other information which can be obtained by a vehicle-road cooperation technology, red light running probability calculation is carried out on vehicles in a road through a free flow and following state of the road; the probability of the dilemma areas at different distances, different speeds and different time is calculated through an MATLAB writing program, and a database (a vehicle red light running recognition algorithm) is established, so that the red light running probability in the road can be calculated in real time; and finally, the informationis transmitted to a vehicle running on the road through an early warning system, and the vehicle can quickly make a judgment, thereby greatly reducing the probability of running the red light. By calculating the red light running probability of the vehicle and establishing the vehicle identification database, the decision of a driver is effectively improved, so that the red light running probability of the vehicle is greatly reduced, and great convenience is brought to urban managers and vehicles.
本发明公开了一种在车路协同条件下的车辆闯红灯预测方法。本发明中,首先基于车路协同技术可获取的车辆GPS位置信息、速度信息、交叉口停车线位置信息、信号灯相位等信息:通过道路自由流和跟驰状态下,对道路中的车辆进行计算闯红灯概率计算;通过MATLAB编写程序计算出不同距离不同速度不同时间下的两难区概率,建立数据库(车辆闯红灯识别算法),从而可以实时的计算出道路中闯红灯概率;最后通过预警系统,传递给在道路上行驶的车辆,车辆可以迅速的做出判断,从而大大减少闯红灯的概率;通过计算车辆闯红灯概率,建立车辆识别数据库有效提高驾驶员的决策,从而大大减少车辆闯红灯概率,对城市管理者和车辆拥有着有着极大的便利。
