This paper describes results of the second phase of the Field Operational Test FAST-TRAC - "Faster and Safer Travel through Traffic Routing and Advanced Controls" in Oakland County, Michigan. The mission of the FAST-TRAC program has been to implement an operational field test of a combined Advanced Traffic Management/Advanced Traveler Information System, the first of its kind in the United States. The paper focuses on the ATIS side of FAST-TRAC, the ALI-SCOUT Dynamic Route Guidance System, as well as on its conceptual integration with FAST-TRAC's ATMS component, the SCATS (Sydney Coordinated Traffic Adaptive System) system. Starting in 1991, ALI-SCOUT has grown through several phases from a small test bed of 16 vehicles to a fully operating system where 100 beacons have provided dynamic route guidance to almost 500 volunteer drivers all over the southeastern part of Oakland County. The system has the potential to interact with the Oakland County Traffic Information Management System (TIMS), the second major component of FAST-TRAC. The third component, SCATS, provides adaptive traffic control to 100 intersections. This unique combination of systems was aimed at providing the basis of a regional Intelligent Transportation Infrastructure. This paper focuses on the accomplishments and results that led to the current status. Major lessons learned as well as unexpected roadblocks are addressed. |
