The invention discloses a road lighting early warning system and early warning method, and the method comprises the following steps: monitoring the rain and fog concentration of each road region of a target road at regular time, so as to judge whether the rain and fog concentration is greater than a preset threshold value or not; when the rain and fog concentration of any road area is larger than a preset threshold value, position distribution information of all vehicles in the corresponding road area is obtained, and the rear safety distance range of each vehicle in the road area is calculated according to the rain and fog concentration and the position distribution information; and according to the position distribution information and the corresponding rear safety distance range, directional early warning illumination in the rear safety distance range is carried out on each vehicle in the road area. According to the technical scheme, when the rain and fog concentration is large, directional early warning illumination within the rear safety distance range can be conducted on each vehicle in the road area with the large rain and fog concentration through the guardrail lamp beside the road, and therefore the driving safety in the rain and fog weather is greatly improved.

    本申请公开一种道路照明预警系统及预警方法,其道路照明预警方法包括以下步骤:定时监测目标道路的每一道路区域的雨雾浓度,以判断雨雾浓度是否大于预设阈值;当任一道路区域的雨雾浓度大于预设阈值时,获取对应的道路区域内所有车辆的位置分布信息,并根据雨雾浓度和位置分布信息,计算道路区域内每一车辆的后方安全距离范围;根据位置分布信息和对应的后方安全距离范围,对道路区域内的每一车辆进行后方安全距离范围内的定向预警照明。本技术方案,其可在雨雾浓度较大时,通过道路旁的护栏灯对雨雾浓度较大的道路区域内的每一车辆进行后方安全距离范围内的定向预警照明,以大幅提升雨雾天气中的行车安全。
