Research On Safety Evaluation Of Rural Highway Linear Design Based On Vissim Simulation

With unceasingly expanding scale and gradually improving quality and connection depth, rural highway are developing rapidly in recent years. The study on rural highway traffic safety are becoming more and more important.Based on rural highway as research object, this paper provided a good analysis of the rural highway traffic safety situation, found the main problems of rural highways, proposed the influence factors of rural highway traffic safety, and determined weights of such factors using improved gray correlation analysis. Firstly, VISSIM simulation software were used to simulate and evaluate rural highways route design safety. The routes against safe were reconstruted, and the routes unable to be rebuilt were disposed with traffic engineering measures. Secondly, the study of rural highway traffic safety began from rural highway route design, and the rural highway route design standards were put forward. According to the implementation situation of the rural road traffic safety project since 2004, the paper also conducted study on rural road traffic safety facilities.The measures for rural highway safety facilities were provided.This paper studied the rural highway route design and rural highway traffic safety engineering. Using concepts of economy, tolerance, flexibility in the study on the rural highway is an innovation. And adaption of VISSIM simulation software in the rural highway route design safety evaluation is another innovation. The paper may provide methodology guidance and theoretical basis for rural hiway traffic safety evaluation.
