Tire Road Surface Conditions and 2D Curve Analysis Based Development of Surrogate Safety Measures

Abstract

This paper presents a new comprehensive way to perform safety surrogate measure analysis that uses longitudinal as well as lateral dynamics for vehicle trajectory analysis as compared to traditional methods that use only longitudinal predicted movement for crashes. The paper also introduces, for the first time, longitudinal and lateral adhesion coefficients in the dynamics to account for the interaction between the tires and the road surface that accounts for many road accidents.
