Abstract
This paper describes the initial output from the DIRECT project and provides a discussion of issues relating to the integration of transport data in European cities. The present diversification in processes of transport data collection and exchange are identified, and key barriers to universal inter-operability discussed. Evidence of architectural developments in the United States are used to highlight current limitations of physical, institutional and data structure designs within European urban areas. Specific attention is given to the lack of standardisation both with and between European member states. (A*)
