The invention belongs to the technical field of road traffic safety, and provides a low-delay warning method for sudden dangerous situations of an expressway, which comprises the following steps that: an expressway management platform acquires latitude and longitude coordinates of an accident occurrence position; the operator searches all base stations within a specified distance range by taking the latitude and longitude coordinates as a center, and obtains the position information of a user mobile phone accessed to the searched base station; the safety early warning cloud platform divides the risk level of the base station based on the distance between the base station and the accident occurrence position and the type of the base station, obtains a user mobile phone number accessed to the base station based on user mobile phone position information provided by an operator, and sets the user mobile phone number to be the same as the risk level of the accessed base station; and the safety early warning cloud platform sets prompt frequencies corresponding to the risk levels for the user mobile phone numbers according to the risk levels of the user mobile phone numbers, and automatically calls the user mobile phone numbers with different risk levels according to the prompt frequencies through the artificial intelligence customer service to prompt.

    本发明属于道路交通安全技术领域,提出了一种面向高速公路突发危险情况的低时延警示方法,包括:高速公路管理平台获取事故发生位置的经纬度坐标;运营商以经纬度坐标为中心,搜索规定距离范围内的所有基站,并获取与搜索出的基站接入的用户手机位置信息;安全预警云平台基于基站距离事故发生位置的距离和基站类型对基站的风险等级进行划分,并根基运营商提供的用户手机位置信息,获取与基站接入的用户手机号码,并将用户手机号码设置为与接入基站相同的风险等级;安全预警云平台根据用户手机号码的风险等级分别为其设置与风险等级对应的提示频率,并通过人工智能客服按照提示频率向不同风险等级的用户手机号码自动拨打电话进行提示。
