Abstract
Report of the Delft University of Technology, Department of Transportation Planning and Highway Engineering in assignment of Philips International B.V. Aim of the study was to determine the possible posi tive and negative effects on traffic safety of the Carin Car Information and Navigation system and to define requirements by which the possible negative effects are minimized or possibly eliminated and the possible positive effects are enhanced, thus making the overall effect of Carin on traffic safety a positive one. The Carin system has been analysed with the so-called phase model of the accident process. Possible positive effects that resulted from this analysis, are: avoidance of search behaviour, avoidance of detours, avoidance of unsafe locations and situa tions, and informa tion on the vehicle condition. Possible negative effects were: compact disc changing while driving, distraction by route guiding advices, untimely presentation of route guiding advices, obstruction of the driver's view, illegal route guiding advices, the reaction on a disregarding of a route guiding advice, and (part of) the system causing injuries in case of an accident. On an important part of the above subjects a literature study has been conducted. The findings are discussed and gaps in the present knowledge indicated. Priorities for further study are presented.
