Abstract: A driver measure system aids in determining the physical requirements of a disabled driver in order to modify a van or other vehicle to his or her specific needs. The driver measurement system comprises a frame including tracks for positioning a wheelchair and a control assembly which includes a steering wheel and hand controls. Force adjustment and measurement mechanisms for the steering wheel and hand controls enables a trained technician to evaluate the functional driving ability of the disabled driver. The simulator also provides a structural reference framework for taking anthropometric measurements. The measurements obtained are used to prepare a specification or "mobility prescription" for modifications and adaptive driving equipment needed to customize a vehicle.
