摘要

本文研究了环形交叉口上驾驶员视距与车速和碰撞率的关系。收集了26个单车道环形交叉路口的数据，并建立了预测第85百分位进路速度、第85百分位入口速度以及第85百分位进路速度与第85百分位入口速度之差的模型。还开发了考虑驾驶员视距的模型来预测环形交叉路口的车辆碰撞率。模型的结果证实，现代环形交叉路口的车速和撞车事故与驾驶员的视距有关。提供超过最小要求的视线距离可以导致更高的速度，从而降低环形交叉路口的安全性。

The Influence of Driver Sight Distance on Crash Rates and Driver Speed at Modern Roundabouts in the United States

This paper investigates the relationship between driver sight distance and vehicle speed and crash rates at roundabouts. Data were collected at 26 single-lane roundabouts and models were developed that predicted the 85th percentile approach speed, 85th percentile entrance speed, and the difference between the 85th percentile approach and 85th percentile entrance speeds. Models were also developed to predict vehicle crash rates at roundabouts considering driver sight distance. The results from the models confirm that vehicle speeds and crashes at modern roundabouts are related to driver sight distance. Providing more than the minimum required sight distance can lead to higher speeds that reduce safety at roundabouts.
