Summary
The ADVANCE (Advanced Driver and Vehicle Advisory Navigation ConcEpt) project was a major public-private partnership operational test designed to evaluate Intelligent Transportation Systems (ITS) technology, specifically dynamic route guidance using probe vehicles. Conceived in 1989 and formalized in 1991, the project involved the Federal Highway Administration, the Illinois Department of Transportation, Motorola, the Illinois Universities Transportation Research Consortium, and the American Automobile Association. The primary research objective was to test the feasibility of using equipped vehicles as roving traffic probes to collect real-time travel time data, which was then fused with fixed detector data and anecdotal reports to provide drivers with dynamic route guidance to avoid congestion and incidents. The system architecture consisted of four subsystems: the Mobile Navigation Assistant (MNA) for in-vehicle route planning and positioning; the Traffic Information Center (TIC) for central processing and data fusion; the Communications subsystem for radio frequency data transmission; and Traffic Related Functions for algorithmic incident detection and travel time prediction. Initially planned for a deployment of 3,000 units, the project shifted to a "Targeted Deployment" of approximately 75–80 households due to technological and market delays. The test area covered over 300 square miles in the Chicago metropolitan region. Data collection involved volunteer drivers using the MNA during routine trips, with travel times transmitted to the TIC, which processed the information and sent updated route guidance back to the vehicles. The document serves as a compendium of insights and achievements, detailing the challenges and lessons learned across twelve specific domains. Key findings include the complexities of managing public-private contractual arrangements and the technical difficulties of integrating subsystems developed by different organizations at different release levels. The report highlights the effectiveness of the RF subsystem development and the importance of thorough documentation and communication during system integration. It also addresses the logistical challenges of recruiting volunteer drivers, noting that the scaled-down deployment still provided valuable data. Technical sections cover the implementation of traffic algorithms, the performance of probes versus fixed detectors in estimating link travel times, and the estimation of environmental effects on vehicular emissions. Safety evaluations utilized hazard analysis techniques to assess driver performance and error rates, finding that the system did not introduce significant safety risks. The significance of the ADVANCE project lies in its role as a pioneering example of public-private collaboration in ITS development. The compendium provides a comprehensive record of obstacles encountered and methods used to overcome them, offering actionable guidelines for future ITS deployments. The project demonstrated that a targeted deployment could achieve most original goals at a lower budget, validating the technical viability of probe-based traffic information systems. The lessons learned regarding institutional issues, algorithm implementation, and system integration are intended to assist future project managers and developers in advancing state-of-the-art transportation systems.
Key finding
The ADVANCE project successfully demonstrated that a reduced-scale Targeted Deployment of approximately 75 probe vehicles could effectively test dynamic route guidance algorithms and system integration, yielding significant operational lessons for future ITS implementations.
