An Experimental and Analytical Investigation of the Effect of Bus-Induced Aerodynamic Disturbances on Adjacent Vehicle Control and Performance.

摘要

The report investigates the nature and magnitude of the effect of bus-induced aerodynamic disturbances on adjacent highway vehicles. The study comprised full scale experiments,wind tunnel tests and driver/vehicle/disturbance response and performance analyses. The results are expressed terms of overall driver/vehicle safety performance,with emphasis on steering control and side to side deviations of the disturbed vehicle's path along the roadway. The basic situations studied involve a station wagon and an intercity bus, a two lane road,overtaking and passing and vehicle-bus oncoming. Within this framework the following parameters were varied: bus width and shape,lateral separation and lane width,ambient wind magnitude and direction,vehicle-bus speeds,and driver skill and alertness.
