Investigation of how ACC influenced workload, comfort and driving behaviour for drivers with disabilities.
Simulator study of 20 individuals with disabilities who were experienced in driving adapted vehicles (completed at least 40,000 km). Subjects drove 100km on two lane roads with and without ACC and were asked to react to certain triggers along the route by braking.
Subjective workload was lower and performance better when using the ACC system.
Subjects felt they could control speed and distance to leading vehicles better when using ACC. They trusted the system.Use of ACC did not influence reaction time, speed, or lateral position.
The study concludes that ACC decreases workload, increases comfort without a negative effect on safety.

Study goes some way to proving the anticipated benefits of adaptive cruise control. However the sample is small and it could be argued that a simulator trial does not fully replicate using and trusting such technology in a ‘real world’ situation.
