Abstract

Field studies were designed to measure the effects of pavement markings on driver behavior at freeway lane drop exits. Number and location of lane changes and erratic maneuvers upstream of three lane drop exits were the measures of effectiveness used to describe driver behavior. The data from two sites directly revealed--and the data from a third site indicated--that drivers are moving into or out of the exiting lane further upstream of the lane drop gore in the in the after period than in the before period. The before-and-after studies also revealed that the number of erratic maneuvers within the entire study segment decreased with the installation of the markings. The largest decrease was in the number of one-lane lane changes through the gore.
