Surrogate safety measures using bicycle vehicle models

Abstract

Surrogate Safety Measures (SSM) allow for analysis of crashes without having access to actual crash data as those are difficult to obtain, being of rare event nature. This article, for the first time, uses kinematic and dynamic bicycle models for vehicles for trajectory analysis to compute surrogate safety measures. The model has two versions, with and without the consideration of adhesion coefficients depending on the road conditions. Previously, only longitudinal models have been used and recently, a combined longitudinal and lateral model has been used by the authors but with a single wheel model, which is being enhanced by using the bicycle model in this paper.
