Abstract
:
The objective of this study has been to determine the feasibility and format of a grade severity rating system (GSRS) so that existing countermeasures can be more rationally applied and the need for new countermeasures can be established. The study as conducted consisted of a literature review, the development of a truck downgrade braking model, a series of field tests to validate the model and the final development of a prototype grade severity rating system. With the grade severity rating system a downgrade may be given a numerical rating based on the severity of the grade. A speed selection model was also developed that can be used to determine a safe speed of descent based on the grade severity rating and the weight of the truck.
