In Canada, a national Intelligent Vehicle-Highway System [IVHS) - or Road Transport Informatics (RTI) or Advanced Telematics in Road Transport (ATRT) - program is under active development at present. To reach this stage, many parallel activities had to be pursued, particularly over the past four years. These have included research and demonstration projects on freeway traffic management systems and commercial fleet applications, state-of-the-art reviews of mobile systems technologies - and two major conferences, one on vehicle navigation and information systems, the other on automatic vehicle identification. This paper recalls some of the main events and progress made over this period and outlines current work in identifying Canadian invoLvement in the IVHS field. It is an update on a paper presented at the RTI/IVHS Conference of 24th ISATA (Florence, Italy, 20-24 May 19911 bringing into focus the most recent developments.

A major impediment to the widespread implementation of Intelligent Vehicle Highway Systems (IVHS) is the absence of communications standards, particularly for mobile applications. The Communications Committee of the Transportation Research Board (TRB) sponsored a Communications Workshop in June 1990 to address this problem. The Workshop was attended by representatives from all levels of government, consultants, universities and industry from the United States, Canada, Europe, and Japan. Working groups were established to address specific issues, including research requirements, international compatibility, commonality and interoperability, content and format, and processes for developing standards. Problem statements generated by the working groups formed the basis for recommended action.
