Project Description

Travlink sought to achieve several objectives -

  • Measuring customer acceptance of new technologies
  • Identifying changes in transit ridership due to improved customer information
  • Determining the performance of ITS technologies in the real world environment
  • Evaluating the impacts on transit service efficiency and quality


Travlink was focused toward encouraging commuters to consider alternatives to single occupant travel, especially public transit. 


The Travlink Project included Computer Aided Dispatch (CAD)/Automatic Vehicle Location (AVL), Automatic Vehicle Identification, and Advanced Traveler Information Systems (ATIS). Differential Global Positioning System (GPS) technology was used to provide accurate location information every 30 seconds for 80 public transit buses operating on ten routes. The 3M Opticom system was also installed on the 80 buses to allow them to function as probe vehicles. Four types of devices made up the ATIS component, which distributed information via dial-up phone lines - interactive touch-screen kiosks in downtown Minneapolis, electronic signs and display monitors at transit park and ride lots along I-394, and on-line information service to 315 homes and offices of recruits. GPS receivers located the buses accurately as they followed their routes. Route schedule adherence was determined and the information was displayed on the driver's keypad as well as at the devices. The transit control center and the traffic management center are connected by a fiber optic link which carried the bus status information to be displayed to commuters.
