考虑交通安全的运煤公路选线评价方法

Evaluation method of heavy haul coal transportation highway line selection considering traffic safety

选线是运煤公路建设前期最重要的工作之一,为了更好地从交通安全角度对运煤公路的选线方案进行评价,采用密切值法并选取与交通安全相关的多个平纵线型指标,从而构建完整的评价指标体系。将已构建的评价指标体系应用于工程实例中,从交通安全的角度对运煤公路某路段的K线和B线两种选线方案进行比选。密切值法的评价结果表明,B线的评价结果优于K线,即B线的安全性更好,且密切值法的选线结果与实际工程选线结果一致,说明所构建的评价体系有效,采用密切值法对运煤公路选线进行评价是可行的。

Line selection is one of the most important tasks in the early stage of coal highway construction, in order to evaluate the line selection from the perspective of traffic safety, the close-value method is adopted to select plane and vertical indicators related to traffic safety, so as to build a complete evaluation index system. The evaluation index system is applied to the project example, and K line and B line of a certain road section of coal highway are compared from the perspective of traffic safety. The evaluation results of the close-value method show that K line is better than B line, that is, the safety of K line is better, and the line selection result of the close-value method is consistent with the actual engineering line selection, which indicates that the proposed evaluation system is effective, and it is feasible to use the close-value method to evaluate line selection of coal highway.
