LATERAL VEHICLE PLACEMENT AND STEERING WHEEL REVERSALS ON A SIMULATED BRIDGE OF VARIABLE WIDTH

The research reported here utilized a Greenshield's Drivometer and a Super 8 mm time-lapse movie camera to record steering reversals and lateral placement in the vicinity of a simulated highway bridge. Eight male and two female subjects were tested for eight shoulder width conditions. Each subject drove the instrumented test vehicle across the simulated 50-foot bridge for a total of 30 runs for each of the eight test conditions. Statistical and graphical analysis of the data showed considerable variation between the individual subjects. However, certain trends were shown for all subjects. Steering reversals, both minor and major, were relatively constant for shoulder widths greater than 4 foot. The distance of vehicle from centerline of roadway also reached a maximum for a 4-foot to 6-foot shoulder width. The subjects tended to drive closer to the centerline for shoulder widths less than or greater than approximately 4 feet to 6 feet. These results indicate the need for a minimum shoulder width of 4 feet if traffic operations are not to be influenced. /Author/
