One of the main tasks of PRO-GENERAL (as a sub-programme of PROMETHEUS) is to design traffic control systems using new technologies, at the functional level and from the traffic engineering point of view. Accordingly, the industrial companies involved described more than 20 functions as a basis for further work. The PROMETHEUS Safety Group selected some functions which seemed to have a noticeable impact on road traffic safety. Under consideration of different accident databases (for example indepth-study data), an assessment was made of the potential accident reduction which could be gained from the designed PROMETHEUS functions. Starting from the assumption of perfect functions, some of them showed relatively great effectiveness in terms of accident reduction. However, some functions which seemed to be useful will have only a very small impact on road safety. The assessed benefits will diminish considerably, provided that real traffic and road situations including real drivers are taken into account. (A)
