Abstract:An unobtrusive study was made of vehicles approaching low-volume, uncontrolled cross-intersections, with restricted right sight distances, at which the give-way-to-the-right rule was operative. The hypotheses were that one factor that influenced motorists' approach speeds on the major road was the frequency with which vehicles emerged from the right and that most drivers exceeded the safe approach speed when this probability was low. The mean speeds at a lowand a high-probability intersection were 31 mph (SO k… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
