The WG 1.1 has covered, from a Canadian perspective, current practice and research needs
in telematics-based traffic and travel information systems (TTIS). Also, comparisons are
made with other ATLANTIC partners. Specifically, four inter-related TTIS services were studied.
These are traffic information, public transit and multimodal traveller information, road
condition information, and road weather information. Themes explored relate to information
needs, consumer interest, business issues, reliability of information, adding value to real-time
information by making predictions (e.g., predictive travel time) for origin to destination
travel, and technological factors such as infostructure and wireless communications.
Another notable activity of the WG1.1 is participation in the development of the Orange
Book on "Predictive Travel Time". In addition to participation in teleconferences, the WG1.1
played a role in the Orange Book Workshop held in July 2003 at Carleton University. The Orange
Book project is co-sponsored by ITS America's Special Interest Group on International Research
& Learning and two U.S. private sector firms, TrafficCast and PBS&J. Highlights of the findings
reported in the draft Orange Book are noted in this discussion paper (PBS&J 2003).
