A Study on Overtaking Behavior on the Slippery Road

Abstract

Overtaking behavior on two-lane and slippery road becomes more difficult because tire-road friction coefficient drops. In this study, overtaking behavior model considering slippery roads is developed and analysis of overtaking behavior is conducted. That is, by developing passing sight distance estimation model and aborting model, analysis of overtaking and aborting behavior on slippery road is conducted. As a result, the following facts are clarified. The length of overtaken vehicle, overtaking vehicle's speed and road conditions affect passing sight distance. The overtaking vehicle's speed and road conditions affect aborting behavior.
