LANE BEHAVIOUR OF MOTOR VEHICLES ON A TWO LANE HIGHWAY

SPURVERHALTEN VON KRAFTFAHRZEUGEN AUF EINER ZWEISPURIGEN LANDSTRASSE

MEASUREMENTS WERE CARRIED OUT ON A TWO LANE HIGHWAY HAVING A LANE WIDTH OF 3,50 M AND AN EDGE STRIP OF 0,50 M AND DENSITY DTV 73 OF 17128 VEHICLES PER 24 H TO DETERMINE IF AND TO WHAT EXTENT SUCH FACTORS AS VARYING SPEED, TRAVELLING IN CONVOY, EFFECT OF ONCOMING TRAFFIC AND TRACK OF THE VEHICLE HAVE ANY INFLUENCE ON THE DRIVERS DISTANCE FROM THE GUIDING LINE. INFORMATION CONCERNING LANE BEHAVIOUR WAS OBTAINED USING LIGHT BEAMS AND REFLECTORS AFFIXED TO THE GUIDE LINE. THE INVESTIGATION SHOWED THAT THE USE OF THIS METHOD ENABLED THE DISTANCE BETWEEN THE OUTER EDGE OF THE LEFT TYRE AND THE CENTRE OF THE ROAD (GUIDE LINE) TO BE DETERMINED WITH AN ACCURACY OF 4,0 CM. THE RESULTS OF THE MEASUREMENTS INDICATED THAT THIS DISTANCE IN FREE TRAFFIC DEPENDS ON THE SPEED AND TRACK OF THE VEHICLE. TO DETERMINE THE INFLUENCE OF CONVOY FORMATION AND ONCOMING TRAFFIC, ATTENTION WAS CONCENTRATED ON VEHICLES WITH TRACK WIDTHS OF 1,30 TO 1,50 M AT SPEEDS OF 50 TO 100 KM/H. IT WAS FOUND THAT WITH ONCOMING TRAFFIC THE CARS TRAVELLED AN AVERAGE OF 15 CM FURTHER TO THE RIGHT.
