The invention provides an urban intersection traffic safety risk assessment method and system. The method comprises the steps that index data of static indexes and index data of dynamic indexes of an intersection are acquired; the static indexes and the dynamic indexes are analyzed according to the index data of the indexes and a preset index risk quantification mapping table, and quantification results corresponding to the index data are obtained; and calculating a risk value of the intersection according to a quantitative result of each index, determining a risk level of the intersection by screening the risk value according to a preset risk level, and performing traffic safety risk assessment according to the risk level. According to the method, different levels of risk point locations are screened by constructing quantitative indexes, index selection is scientific and reasonable, risk hidden danger investigation can be more convenient and efficient, and dependence of manual investigation on working experience of investigation personnel is weakened.
本发明提供一种城市交叉口交通安全风险评估方法及系统,方法包括:获取交叉口的静态指标的指标数据及动态指标的指标数据;根据各指标的指标数据与预设指标风险量化映射表对静态指标及动态指标进行分析,获取与各指标数据对应的量化结果;根据各指标的量化结果计算交叉口的风险值,并通过将风险值按照预设风险等级进行筛选来确定交叉口的风险等级,根据风险等级进行交通安全风险评估。本发明通过构建量化指标来筛选不同等级的风险点位,指标选取科学合理,能够使风险隐患排查更加便捷高效,减弱人工排查对于排查员工作经验的依赖。
