ANALYSIS OF SIGHT DISTANCE NEEDS FOR PASSING TRUCKS ON UPGRADES

A special case of passing maneuvers needs to be considered when a passenger car is trailing a truck and both have to accelerate on an upgrade from zero speed. This paper examines the effect of road geometry on the passing sight distance (PSD) requirements and expected driver behavior. A stepwise modeling of the passing maneuver is used to determine the required PSD to abort or complete the pass at any time with the corresponding speeds of the passing and impeding vehicles. From the results, it can be concluded that PSD based on the need to complete the passing maneuver should be used since PSD based on the concept of critical position may be unsafe.
