The ADVANCE (Advanced Driver and Vehicle Advisory Navigation Concept) project is an ATIS demonstration project located in eastern Illinois. The in-vehicle navigation testing portion of the project has now been completed. Over a seven month period, up to 75 vehicles were utilized in a 300 square mile area. The vehicles utilized differential GPS navigation as well as dead reckoning and map matching to navigate their way through the test area. The vehicles also acted as probes, sending real-time travel information to a Traffic Information Center (TIC) that in turn transmitted the information to other vehicles as an aid in dynamic route planning. The project was a joint effort of the Federal Highway Administration (FHWA), the Illinois Department of Transportation (IDOT), the Illinois Universities Transportation Research Consortium (composed of the University of Illinois at Chicago and Northwestern University), Motorola and the American Automobile Association. De Leuw, Cather & Company was responsible for system engineering, system integration, assisting in project management, and the evaluation of the Traffic Information Center. This paper focuses on the ADVANCE TIC architecture evaluation which had the overall goal of assessing the degree to which the implemented TIC architecture and operational practices met the needs of all the agencies involved in or affected by the system operation. To achieve this, several aspects of the performance of the various TIC subsystems, both individually and as a complete system, were assessed. |
