“…For example, some have used simulations to study driver response to roadway departure [21]. Others have concentrated on off-road ride comfort [22] and some have focused on friction influences due to water or snow [23]. While these applications are diverse, few people to date have looked specifically at the use of vehicle dynamics to analyze and optimize the roadway design itself.…”

Safety is a crucial consideration in the design of roadways, yet formal tools to study roadway safety prior to construction are often quite limited. As a possible new tool, this work investigates the iterative use of vehicle dynamic simulations to study vehicle-roadway interaction in order to optimize highway design for safety. Following a discussion of the history and accuracy of vehicle dynamic simulations, a methodology of roadway geometry analysis is presented. This methodology is demonstrated by an example scenario studying the safety of a depressed median of a rural highway when there is an in-median incursion. The vehicle type, vehicle speed, vehicle trajectory, and the driver’s corrective maneuvers are all varied in a simulation-based analysis to evaluate their respective effects on vehicle behavior including vehicle orientation, trajectory, and instabilities.

“…In all probability, an alternative suspension means, besides a seat suspension, will be required to improve the operator ride comfort. Based upon the review of the ride comfort means [Claar et al, 1980a], a chassis isolation system was selected for further investigation as a means to attenuate ground-induced motion between the axles and the chassis. Several desirable features of the concept were identified as:…”

The development of a chassis suspension system for an agricultural tractor has been described to improve the operator ride comfort. Computer simulation tech-niques were used to formulate the tractor models and to compute the natural frequencies and frequency response of the models, as well as the RMS acceleration response, to evaluate the effect of the suspension system and cab position on operator ride comfort.
