R & D efforts have been going on for over ten years in Europe, at European Community, international, and at national, local or company level, and also in Japan. More recently, in 1991, the IVHS Programme was launched in the USA. After such huge R & D efforts have shown that ATT is a potent tool to help in solving today's main problems of mobility: congestion, safety, environmental impact and user comfort, it could be expected that the technologies which have been successfully developed would quickly come into widespread use. This is not yet the case. This paper tries to identify the main reasons for the relatively slow deployment of a successful R & D effort. Results from ERTICO's experience during its first two years of operation are given in this paper. (A)
