为了改善公路交通安全状况,完善道路危险源筛选理论和提高道路危险路段排查治理水平,有必要以路为重点研究与我国交通特色相适应的公路交通安全评价指标体系。本文从公路路线平面、视距、纵断面和横断面四个方面进行了路线指标的安全评价体系研究,得出影响公路安全的路线因素,通过工程实例对各指标进行了安全限值分析,并对不满足安全需要的指标采取了相应的优化措施,为设计部门在公路设计中提供了参考。
In order to improve the road traffic safety status, improve the screening theory of road hazard sources and improve the investigation and management level of dangerous road sections, it is necessary to study the road traffic safety evaluation index system which adapts to the traffic characteristics of our country. This paper studies the safety evaluation system of route indicators from four aspects of highway route plane, line-of-sight, longitudinal section and cross-section and obtains the route factors that affect highway safety. Through the engineering examples, the safety limits of each indicator are analyzed. The corresponding optimization measures are taken for the indicators that do not meet the safety requirements, which provides a reference for design department in highway design.
