EFFECTS OF ROADWAY MARKINGS ON VEHICLES STOPPING IN PEDESTRIAN CROSSWALKS

A STUDY WAS CONDUCTED TO DETERMINE THE EFFECT OF ROADWAY MARKINGS WITH REGARD TO VEHICLE ENCROACHMENT ON CROSSWALKS AT SIGNAL-CONTROLLED INTERSECTIONS. THE SEVEN INTERSECTIONS SELECTED FOR STUDY WERE SUCH AS TO PERMIT EVALUATION OF THE EFFECTS OF NUMBER OF LANES, ONE-WAY VERSUS TWO-WAY TRAFFIC, AND PAVEMENT MARKINGS (CROSSWALK, CROSSWALK AND STOP LINE, END OF CENTER LINE). SEX OF DRIVER, TYPE OF VEHICLE, AND VEHICLE DIRECTION AFTER STOPPING WERE OTHER VARIABLES INVESTIGATED. A 16-MM. MOVIE CAMERA WAS USED TO RECORD THE STOPPING POINT OF EACH VEHICLE. VEHICLES WHICH STOPPED CLOSE TO INTERSECTIONS TENDED TO BE DRIVEN BY FEMALES, TO BE TRUCKS RATHER THAN PASSENGER CARS, AND TO TURN AFTER STOPPING. VEHICLES WERE ALSO LIKELY TO STOP FARTHER FROM THE CURB LINE ON FOUR-LANE THAN ON TWO-LANE ROADS. STOPPING POINTS ON ONE-WAY AND TWO-WAY ROADS WERE NOT DISCERNIBLY DIFFERENT. THE PERCENTAGE OF VEHICLES STOPPING ON CROSSWALKS WAS FOUND TO BE SMALLEST AT INTERSECTIONS MARKED WITH A CROSSWALK AND A STOP LINE. A TENTATIVE RECOMMENDATION IS MADE FOR A PLACEMENT OF STOP LINES LIKELY TO REDUCE VEHICLE ENCROACHMENT ON CROSSWALKS TO ACCEPTABLE LEVELS. /AUTHOR/
