The invention discloses a highway ramp exit early warning method, system and device and a storage medium, and the method comprises the steps: obtaining the position information and speed information of a vehicle at the current moment in a detection region, and a plurality of pieces of position information of the vehicle within a set time period before the current moment; the speed of the vehicle at the current moment is compared with a preset speed threshold value, and if the speed of the vehicle at the current moment is smaller than the preset speed threshold value, early warning information is sent; the driving trend of the vehicle is fitted according to the position information of the vehicle at the current moment and a plurality of pieces of position information of the vehicle within a set time period before the current moment, the driving state of the vehicle at the current moment is judged according to the driving trend of the vehicle, and if the driving state of the vehicle at the current moment is parking or backing, early warning information is sent. Under the highway ramp exit scene, monitoring of dangerous behaviors such as ramp exit backing is completed, traffic accidents at the ramp exit are reduced, casualties of drivers and property loss are reduced, and the traffic operation efficiency is improved.

    本发明公开了高速公路匝道出口处预警方法、系统、设备及存储介质,获取检测区域内当前时刻车辆的位置信息和速度信息,以及在当前时刻之前设定时间段内车辆的若干位置信息;将当前时刻车辆的速度与预设的速度阈值进行比较,若当前时刻车辆的速度小于预设的速度阈值时,发送预警信息;根据当前时刻车辆的位置信息与在当前时刻之前设定时间段内车辆的若干位置信息拟合出车辆的行驶趋势,根据车辆的行驶趋势判断当前时刻车辆的行驶状态,若当前时刻车辆的行驶状态为停车或倒车时,发送预警信息。本发明在高速公路匝道出口场景下,完成对匝道出口倒车等危险行为的监测,减少匝道出口处的交通事故,减少驾驶员的伤亡以及财产的损失,提高交通运行效率。
