Work Zone Design Considerations for Truck Operations Pavement/Shoulder Drop-offs

Operational and accident data were analyzed for nine truck study sites in three states. Pavement/shoulder drop-offs were studied by simulation modeling and analytical analyses of the drop-off maneuver and by analysis of operational and accident data from four pavement/shoulder drop-off sites located in two states. Results of the study of truck operations in work zones revealed insufficient design speed of temporary crossover roadways as the most critical truck problem observed. The modeling and analytical analyses of pavement/shoulder drop-off traversals resulted in the development of a 'window of safety' to define maximum tolerable drop-off heights as a function of vehicle speed and adjacent lane width.
