针对山区农村公路交通事故率高、事故烈度大这一现象,通过一种评价方法对山区农村公路进行安全等级评价,以指导相关部门合理地将有限的安保资金用于最需要进行安全改善的危险路段。根据对山区农村公路的调研(主要以万州区、长寿区、武隆区这三个以山区为主要地貌的重庆辖区)所获取的数据进行研究分析,采用加权分析法确定了山区农村公路交通安全评价指标、指标系数及其分值,并通过对安全度的计算划分出山区农村公路的安全等级;最后以万州万家沟水库路段为例进行案例分析,以安全度中评价指标分值较低的指标作为对道路设施进行改造的对象,提高了案例中路段的安全等级,从而验证了评价方法的实用性。
Aiming at the phenomenon of high traffic accident rate and high accident intensity in mountainous rural roads, the paper evaluates the safety grade of mountainous rural roads through an evaluation method so as to guide the relevant departments to rationally allocate the limited security funds to the danger which is most in need of safety improvement Road section. Based on the data obtained from the survey of mountainous rural roads (mainly Chongqing Municipality of Wanzhou, Changshou and Wulong, the three mountainous areas of Chongqing), the weighted analysis is used to determine the safety of rural road traffic in mountainous areas Evaluation index, index coefficient and its score, and divides the safety grade of mountainous rural road by calculating the safety degree. Finally, taking Wanzhou Wanjiagou reservoir section as an example, the case analysis is carried out, and the evaluation index of safety is lower As an object to transform the road facilities, the safety grade of the road sections in the case was improved, which verified the practicability of the evaluation method.
