Driving with adaptive cruise control was studies during exposure to "critical" traffic situations in the VTI driving simulator. The traffic situations focused on functional limitations of the ACC concept. Driver behaviour was compared to unsupported driving and found to be differently influenced depending on the situation (e.g. more collisions among ACC users than among unsupported drivers approaching a stationary queue). Reasonable explanations could be too high driver expectations and overlearned reactions. The effects could neither be explained by increased driver workload nor by decreased level of driver alertness. The ACC was well accepted in spite of its limits capability to handle certain situations. (A) For an abstract of the paper see also IRRD 883844.
