The objective of the project was to evaluate the potential for hazard to trucks operating on crest vertical curves designed to AASHTO standards. A truck performance simulation model (TPSIM) was developed to permit the calculation of sight distance and stopping distance associated with each point along the path of a vehicle traversing a specified crest vertical curve. The total stopping distance is compared to the sight distance at each of a sequence of truck positions along the curve to determine if a hazardous situation exists. The analysis was performed for a range of truck braking characteristics and cab types operating over a complete range of crest vertical curves. The analysis indicates that, for selected curve and truck combinations, there are potential hazards for trucks. A series of conclusions and recommendations are presented.
