Abstract

This paper describes an analytical approach to predicting the steer angle of a vehicle, which is necessary to mount a pavement edge from the scrubbing condition. This steer angle is dependent on a new concept, the effective edge height, pavement edge geometry, travel lane friction and shoulder friction, tire geometry, and tire-cornering characteristics. It is demonstrated how this steer angle prediction can be combined with a vehicle simulation such as highway vehicle object simulation model (HVOSM) to predict vehicle movements, stability, and controllability. It is concluded that this combination of analyses used with driver performance characteristics now allows the study of a variety of factors. These would include all vehicle characteristics defined by HVOSM and many highway properties. Principal among these highway properties are pavement, shoulder and edge surface friction, and edge height and shape.
