Risk identification method for long and large downhill road section of highway in mountainous areas
Risk identification method for long and large downhill road section of highway in mountainous areas
The invention relates to a risk identification method for a long and large downhill road section of a highway in a mountainous area, and the method comprises the following specific steps: 1, employing a multi-term logit accident severity model to analyze the influence on the severity of the traffic accident caused by overspeed driving, illegal loading overrun, brake failure, fatigue driving, misoperation, non-maintenance of a safe vehicle distance, illegal lane change, a wet state of a road surface, illegal parking, illegal overtaking, tire burst and the like directly caused by the traffic accident; identifying whether a plurality of direct causes have significant influence on the severity of the traffic accident; 2, if a plurality of direct causes have obvious influence on the severity of the traffic accident, judging which direct causes have obvious influence on the casualty accident; and 3, if the direct cause has obvious influence on the casualty accident, finding out a depth cause according to the direct cause, and finding out the influence of the depth cause on the accident of the long and large downhill road section of the highway in the mountainous area.
本发明是涉及一种山区高速公路长大下坡路段风险识别的方法，包括以下具体步骤：步骤1：利用多项logit事故严重程度模型，分析交通事故直接致因中超速行驶、违法装载超限、制动失效、疲劳驾驶、操作不当、未保持安全车距、违法变更车道、路面湿润状态、违法停车、违法超车、爆胎等对交通事故严重程度的影响，识别是否存在多个直接致因对交通事故的严重程度有显著影响；步骤2：如果存在多个直接致因对交通事故的严重程度有显著影响，判断哪几个直接致因对伤亡事故有显著影响；步骤3：如果直接致因对伤亡事故有显著影响，根据直接致因找到深度致因，找出深度致因对山区高速长大下坡路段事故发生的影响。
