高速公路运行速度与交通安全关系研究
Relating the Operating Speed and Traffic Safety on Freeways
摘要
Abstract
This paper studies the relationship of freeway traffic safety from the perspective of operating speed. By analyzing the operating speed of different vehicles on freeways, the paper establishes a model that correlates operating speed to crash rate, the speed difference among vehicles to crash rate when design speed at 120 km/h and 80km/h is used in nonlinear regression. This study provides good a reference for the decision of limiting speed to reduce the severity of traffic accidents on freeways.关键词
