Aid for training and evaluation of handicapped drivers

Area of Science:

• Rehabilitation Engineering
• Human Factors Engineering
• Automotive Safety

Background:

• Traditional driver training and evaluation methods may not adequately assess individuals with physical disabilities.
• Quantifying driving ability and progress requires objective, measurable data.
• A need exists for standardized training tools that can adapt to individual needs.

Purpose of the Study:

• To describe an indoor driver-evaluator and trainer-aid vehicle.
• To detail the instrumentation for measuring driving control performance.
• To assess the system's efficacy in evaluating and training drivers, particularly those with physical limitations.

Main Methods:

• Development of an indoor vehicle simulator with instrumented controls (steering wheel, gear shift, brake, acceleration).
• Integration of systems to measure operating force and elapsed time for each control.
• Pilot testing with nine tetraplegic subjects over a 4-week period.
• Comparison of simulator-based evaluations with road tests for licensing.

Main Results:

• The system successfully quantifies student driving ability and progress.
• Instrumentation accurately measures operating force and elapsed time for driving controls.
• Pilot test results showed agreement between simulator evaluation and road tests for licensing among tetraplegic subjects by the third test.
• Variable mechanical resistance elements allow for tailored training.

Conclusions:

• The indoor driver-evaluator and trainer-aid vehicle is a viable tool for assessing and training drivers.
• The system demonstrates potential for improving driver education and evaluation, especially for individuals with physical impairments.
• Objective performance metrics provided by the simulator aid in progress tracking and skill development.
