Abstract

This paper deals with the possibility for construction of the database of the braking friction coefficient on the actual roads from the viewpoint of traffic safety. As the first step of this research, we carry out the measurement and estimation method for road friction characteristics. In this analysis, the magic formula is used to estimate the braking coefficient, the maximum friction coefficient, and the slip ratio that leads to that value. As a result, it is shown that road friction characteristics on actual road surface can be estimated accurately.
