The Advanced Driver and Vehicle Advisory Navigation Concept (ADVANCE) advanced traveler information system (ATIS) demonstration project in northeastern Illinois was re-scoped in late 1994 from its originally-planned deployment of 3,000 - 5,000 in-vehicle navigation units to a so-called "targeted" deployment in which up to 75 vehicles were equipped with devices enabling them to receive real-time traffic information. These devices included 1) global positioning system (GPS) transmitters/receivers that enabled the vehicles while in the ADVANCE study area to serve as dynamic traffic probes as well as recipients of location data; and 2) navigation units that employed a comprehensive map data base and average (static) link travel times by time of day, stored on CD-ROM, which together computed efficient (least duration) routes between any origin and destination in the northwest portion of the Chicago metropolitan area. Experiments were designed to dispatch these equipped vehicles along links at headways or frequencies comparable to what would have been observed had full deployment actually occurred. This paper describes the tests, discusses development of the overall evaluation plan and the evaluation management concept which guided them, and reports on issues and results of data analysis known at time of writing.
