The invention discloses a rail transit urban intersection collision early warning method, relates to the technical field of rail transit, and solves the technical problem of collision risk between trains and vehicles, and the method comprises the following steps: obtaining train operation data, train attribute parameters and traffic signal lamp data of a train operation line; calculating the estimated arrival time t1 when the train travels to the next signal lamp; calculating signal lamp parameters when the train is estimated to arrive at the next signal lamp; when the signal lamp parameter shows that the signal lamp is green, if a safe passing condition is not met, collision early warning data are sent to a train terminal; and when the signal lamp parameter represents a red light, acquiring waiting time T2 of the next green light, and sending red light early warning data to the train terminal. The invention further discloses a rail transit urban intersection collision early warning system. According to safe traffic calculation, a train driver can be guided, and the collision risk is reduced; meanwhile, the train can be guided to adjust the operation mode, and safe operation is improved.

    本发明公开了一种轨道交通市区交叉口碰撞预警方法,涉及轨道交通技术领域,解决存在列车与车辆发生碰撞风险的技术问题,方法包括:获取列车运行数据、列车属性参数以及列车运营线的交通信号灯数据;计算列车行进至下一个信号灯的预估到达耗时t1;计算列车预估到达下一个信号灯时的信号灯参数;当所述信号灯参数表示为绿灯时,如果不满足安全通行的条件,则发送碰撞预警数据至列车终端;当所述信号灯参数表示为红灯时,获取下一次绿灯的等待时长T2,发送红灯预警数据至列车终端。本发明还公开了一种轨道交通市区交叉口碰撞预警系统。本发明根据安全通行计算,可以引导列车司机,减小碰撞风险;同时,还可以指引列车调整运行方式,提高安全运营。
