基于Vissim交通仿真的农村公路线形设计安全性评价分析

农村公路是农村经济发展、人民生活条件改善的重要基础条件,同时其在加强城乡联系、调整农业结构、促进农村土地资源开发等方面发挥了重要作用。但是在农村公路深人发展的同时,其交通安全问题严重影响并制约着农村公路的发展态势。通过研究农村公路线形与交通安全关系,运用交通仿真软件对农村公路线形设计进行了安全性评价,并针对其安全问题提出交通安全保障的主要技术手段。

Analysis on Safety Evaluation of Rural Highway Alignment Design Based on Vissim Traffic Simulation

Rural highway is an important basic condition for the development of rural economy and the improvement of people's living conditions.At the same time,it plays an important role in strengthening the urban-rural links,adjusting the agricultural structure and promoting the development of rural land resources.However,with the further development of rural highway,its traffic safety problems seriously affect and restrict the development trend of rural highway.By studying the relationship between the alignment of rural highway and the traffic safety,this paper simulates and evaluates the safety of rural highway alignment design by using the traffic simulation software,and puts forward the main technical means of traffic safety guarantee in view of its safety problems.
