Abstract	Effects of driver behavior of the RTI system CAROSI, providing roadside information on a display inside the car, were studied in a field test. Drivers' opinions about different system aspects were also obtained. Nine subjects between 22 and 59 years, relatively experienced as drivers, participated in the study. Each subject drove a test route in Gothenburg, both in a CAROSI equipped car and in a conventionally equipped car. Generally, the subjects' attitudes to CAROSI were positive, because the system seems to fulfill a need without bringing too much of disturbance. The subjects found the presented information easy to detect and recognize, even if problems could occur due to low visibility in heavy sunshine. The majority also believed that traffic safety, for instance in terms of their own tendency to follow posted speed limits, could be positively influenced by the introduction of a CAROSI-type system. At the same time the subjects denied that CAROSI had influenced their speed choice during the experiment. They also expressed some safety related worries, as they experienced that they, compared to the conventional dashboard, looked at the CAROSI dashboard more often and for longer periods.
