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.
