The guiding principles of traffic planning as applied to road use co-ordination in general and Intelligent Transport Systems (ITS) in particular are analysed. The achievements so far in ITS developments are also examined on the basis of a body of knowledge from the research field Computer Supported Co-operative Work (CSCW). In view of the success of this research field, it is considered that the extension of the methodology and practise of CSCW to ITS holds out a promise of very humane and practical tools for road usage. But there must be a shift from expert systems to an acceptance of the fact that road-users are competent actors on the road, and that road usage is a multifarious practise with broader meaning for the road-users than being guided around. A case from the context of public transport is also discussed with a suggestion of a first prototype for road talk informatics. For the covering abstract see ITRD E114174.
