The invention discloses a warning method for an urban suburb intersection without signal lamps. The warning method comprises the following steps: firstly, measuring initial speeds of motor vehicles and non-motor vehicles; digitalizing non-quantifiable factors of people, vehicles, roads and environments, establishing a vehicle speed influence factor model, and correcting the vehicle speed Vj1; calculating a conflict area according to the intersection, and calculating a conflict probability according to the corrected speed of the motor vehicle and the speed of the non-motor vehicle; and judging a warning mode through a conflict result, judging a warning result again after a single warning is finished, establishing a motor vehicle waiting threshold model, and warning the motor vehicle after the waiting time of the non-motor vehicle exceeds a set threshold. According to the invention, the accident rate of suburban intersections without signal lamps is reduced, and the safety of road driving in suburban areas is guaranteed.
本发明公开了一种城市郊区无信号灯交叉口的警示方法,首先测出机动车与非机动车的初始速度;将人、车、路、环境不可量化的因素数据化,建立车速影响因素模型机动车速度Vj1进行修正;根据交叉口来计算冲突区域,并根据机动车修正后的速度与非机动车速度计算发生冲突的概率;通过冲突结果来判定警示方式,在单次警示结束后,再次对警示结果判定,建立机动车等待阈值模型,当非机动车的等待时间超过设置的阈值后,再对机动车进行警示。本发明降低了城郊无信号灯交叉口的事故发生率,保障了城郊地区中道路行驶的安全。
