Aerodynamic inputs to a parked vehicle caused by a passing bus.

On high speed, duel lane expressways, such as the interstate highway system, drivers encountering problems usually park their vehicles on the highway shoulder in close proximity to the outer lane. If a tire change is required, then the vehicle must be jacked up and the aerodynamic inputs from passing vehicles become a design criteria for jacking up the system. The study covered by this paper was carried out to determine the magnitude and time history of these aerodynamic forces and moments.
