The invention discloses a traffic safety risk early warning method and system based on traffic flow characteristic data, and belongs to the technical field of traffic safety. Comprising the following steps: acquiring a traffic safety comprehensive characteristic index, a real-time traffic characteristic index and a traffic risk influence factor of an expressway section, and analyzing to obtain historical risk data of the expressway section based on the real-time traffic characteristic index in combination with real-time environment data of the expressway section, and comprehensively processing the traffic safety comprehensive characteristic index, the traffic risk influence factor and the historical risk data to obtain a traffic safety risk value of the highway section, and executing corresponding traffic safety risk early warning. According to the invention, the traffic safety risk value is obtained by integrating the traffic safety comprehensive characteristic index, the traffic risk influence factor and the traffic risk data, and early warning is carried out, so that the effect of accurately and effectively carrying out early warning on the traffic safety risk of the highway section is achieved; the problem that early warning of traffic safety risks is inaccurate and not timely in the prior art is solved.

    本发明公开了基于交通流特征数据的交通安全风险预警方法及系统,属于交通安全技术领域。包括以下步骤:获取高速公路路段的交通安全综合特征指数、实时交通特征指数和交通风险影响因子,基于实时交通特征指数,并结合高速公路路段的实时环境数据,分析得到高速公路路段的历史风险数据,综合处理交通安全综合特征指数、交通风险影响因子和历史风险数据得到高速公路路段的交通安全风险值,执行相应的交通安全风险预警。本发明通过综合交通安全综合特征指数、交通风险影响因子以及交通风险数据得到交通安全风险值并进行预警,达到了精准有效的对高速公路路段的交通安全风险进行预警的效果,解决了现有技术中交通安全风险的预警不准确和不及时的问题。
