DRIVER'S JUDGMENT IN OVERTAKING AND PASSING

DRIVERS' JUDGEMENT IN VEHICULAR OVERTAKING AND PASSING ARE STUDIED USING FAMILIAR (DRIVERS'S OWN) CARS AND AN UNFAMILIAR GOVERNMENT VEHICLE AT SPEEDS OF 18, 30, AND 50 MPH. DRIVERS WERE NOT ABLE TO ESTIMATE PASSING DISTANCES ACCURATELY. AVERAGE ERRORS OF ESTIMATION FOR THE DIFFERENT CONDITION VARIED FROM 20 TO 50% OF THE ACTUAL OVERTAKING DISTANCE. ERRORS OF UNDERESTIMATION, WHERE THE MANEUVER REQUIRED MORE SPACE THAN JUDGED, INCREASED WITH SPEED. AT 18 MPH, 15% OF THE ESTIMATES MADE BY DRIVERS WERE UNDERESTIMATES: AT 50 MPH 68% WERE UNDERESTIMATES. THERE WERE NO DIFFERENCES OBSERVED ATTRIBUTABLE TO FAMILIARITY WITH THE CAR. /AUTHOR/
