Abstract:
ANALYSIS OF THE COMPLEX NATURE OF DRIVING PRACTICES REQUIRES THE BREAK-DOWN OF THE STUDIES INTO A NUMBER OF INDEPENDENT, YET CLOSELY RELATED PARTS. ONE SERIES OF STUDIES UNDERTOOK TO DETERMINE FOR VARIOUS SURFACE AND ROADSIDE CONDITIONS THE TRANSVERSE POSITIONING OF VEHICLES ON THE PAVEMENT. A SECOND SERIES DEALT PARTICULARLY WITH THE DISTRIBUTION OF VEHICLE SPEEDS AND LONGITUDINAL SPACINGS, AND THEIR VARIATION WITH CHANGES IN ROAD AND TRAFFIC CONDITIONS. ANOTHER PHASE WAS CONCERNED WITH THE PRACTICE FOLLOWED IN PASSING UNDER A WIDE VARIETY OF CONDITIONS TO SHOW NOT ONLY THE PHYSICAL MEASUREMENTS OF TIME AND SPACE INVOLVED IN SUCH MANEUVERS, BUT ALSO THE NUMBER AND TYPE OF MANEUVER THAT MAY BE EXPECTED UNDER ANY GIVEN CONDITIONS. STILL ANOTHER ANALYZED THE EFFECT OF GRADES ON ALL DRIVING PRACTICES, WITH PARTICULAR REFERENCE TO COMMERCIAL VEHICLES. /AUTHOR/
