Abstract

The aim of the work described in this paper is to determine, quantitatively, the implications for driver and vehicle of attempting to follow a given curve, precisely as it is set out. A prescribed-trajectory vehicle model is used, which allows the computation of the steer angle history necessary for the vehicle to precisely follow a given horizontal and vertical road alignment. In numerical experiments, the effect of changing various transition curve design parameters is explored in terms of the compatibility between the roadway input visible to the driver and the control response required of him, and in terms of the transient vehicle motions and body forces experienced. The vehicle model is also used to compare the consequences of the different detailed design practices employed by different highway authorities when designing curves for the same nominal conditions.
