车辆运行速度影响因素分析

Analysis of influencing factors of the vehicle of running speed

本文从公路沿线道路环境、平面线形设计的合理性、纵断面曲线要素三方面叙述运行速度对交通安全带来的影响。在对车辆运行速度影响因素做充分分析的基础上,提出公路线形设计中要考虑以上三方面因素,使设计速度与行驶速度相对吻合。

In this paper,the author describes the influence of rtmning speed on traffic safety from three factors--the road along the highway environment, the rationality of the design of plane alignment and longitudinal profile carve. On the basis of making full analysis of the influencing factors on the running speed of the vehicle,the author puts forward the above three factors to consider in the design of highway alignment to make the design speed and running speed is relatively consistent.
