TripCheck Local EntryThe TripCheck Local Entry (TLE) tool allows local agencies to input planned and real-time information about their roadway network so that it can be disseminated to travelers through the TripCheck system or to TTIP subscribers, which includes public agencies, commercial information service providers, and other interested parties.
TripCheck SystemTripCheck is the statewide public traveler information service provider for Oregon. The system provides various types of traveler information pertaining to road conditions, weather, construction, transit, traveler services, etc. Information from the TripCheck system is disseminated by ODOT through various means: the Internet (, 511 highway advisory telephone, formatted cable television presentations, TripCheck mobile, Twitter, etc.
TripCheck Traveler Information PortalThe TripCheck Traveler Information Portal (TTIP) system collects, processes, stores, and disseminates transportation information to regional agencies and commercial information service providers. This system collects public agency transportation information about roadways, construction, parking, special events, road closures, etc. and allows subscribers to retrieve information from the broker. Some public agency information is not accessible to commercial information service providers for security reasons. TTIP has been deployed in the Portland metropolitan area and will ultimately be expanded to a statewide level. See the Traveler Information Operational Concept for detailed stakeholder roles and responsibilities.
