基于可靠度的公路交通安全工程评估与应用分析

通过对三级道路交通安全工程分析和研究，从自然条件、路线条件、路侧条件等8个方面选取了28项对公路的交通安全影响较大的因素作为评价指标，建立了公路交通安全的评价指标体系。基于安全可靠度充分考虑各个影响因素之间的关系，运用层次分析法和模糊数学理论确定公路交通安全状况的模糊综合评价模型，提出了基于安全可靠度的用于评价公路交通安全的模糊综合评价方法，并结合国道212线甘肃省境内漳县段交通安全状况进行实例分析，结果表明，在安全可靠度满足要求条件下该方法与公路部门的调查具有很好的吻合性，能很好地反映该公路的交通安全状况。

AHP-Fuzzy Synthetic Evaluation on Traffic Safety of Highway on the Basis of Reliability

Based on analysis of traffic safety of third class highway in western area, the text has adopted 28 more important influence factors as the evaluation index from eight aspects, which is natural condition, route condition, and roadside condition and so on. With the help of safety reli;bility, it has set up the evaluation index system of third class highway traffic safety. The fuzzy synthetic model was built 9y adopting AHP and fuzzy mathematics theory. The instance of G212 in Zhangxian Country of Gansu Province is calculated and analyzed with this method, and if the safety reliability satisfied the need, the results are agree with investigates of highway management department. The method can reflect the traffic safety of third class highway in western area.
