Abstract

Drivers' reactions to warning and tutoring messages, triggered by violations or unsafe behaviour, were studied. Tests were carried out in an instrumented vehicle on the road, as well as in an advanced driving simulator. Information regarding local restrictions entered the vehicle at the moment of passing traffic signs through microwave communication. Compared with a control group of drivers who had only received the instruction that their behaviour would be monitored, the experimental group showed the largest increase in law compliance in the condition where auditory feedback was given. Speed limit violations, following of lead cars at short headways and stop violations were significantly reduced in number and extent. Mental workload, however, as measured using a unidimensional scale, was increased in the case of tutoring. Ratings of acceptance collected after the test rides showed that the drivers considered the system supportive, but their evaluation of comfort was negative.
