Summary
This document serves as a compendium of executive summaries for Field Operational Tests (FOTs) conducted under the United States Intelligent Transportation Systems (ITS) Program. The ITS Program aims to apply advanced technologies to enhance the safety and efficiency of the nation’s surface transportation system, organized around metropolitan and rural travel management, commercial vehicle operations, and intelligent vehicle initiatives. The text provides detailed overviews of several specific projects, including the Adaptive Urban Signal Control Integration (AUSCI), the Advanced Driver and Vehicle Advisory Navigation Concept (ADVANCE), the Advanced Rural Transportation Information and Coordination (ARTIC), the Advantage I-75 Mainline Automatic Clearance Project, and the Alternate Bus Routing (ABR) System. The ADVANCE project, conducted in the Chicago suburbs, evaluated a dynamic route guidance system using in-vehicle devices and probe vehicles. Results demonstrated that Dynamic Route Guidance (DRG) could reduce travel times by approximately 4 percent, particularly during non-recurrent congestion. The study confirmed that probe vehicle data was highly accurate, with 99.4 percent of reported values deemed reliable, and that only three probe vehicles traversing a link within a five-minute interval were sufficient for accurate measurement. However, users expressed reservations about the system’s route suggestions, preferring more control and an "intelligent assistant" model rather than rigid guidance. The Advantage I-75 project tested the Mainline Automatic Clearance System (MACS) along a multi-state corridor to allow transponder-equipped trucks to bypass weigh stations. The Fuel Consumption Test verified that eliminating stops resulted in measurable fuel savings, ranging from 0.05 to 0.18 gallons per station depending on the scale type. Partner states agreed to continue operating the system beyond the test period, indicating successful deployment potential. Conversely, the Alternate Bus Routing (ABR) system on the Garden State Parkway showed limited statistical significance in travel time savings, with differences averaging only two to three minutes. While 80 percent of drivers found diversion messages accurate, many criticized the clarity of audio instructions, and few diversions were actually issued during testing. Other projects highlighted institutional and operational benefits. The ARTIC project in rural Minnesota consolidated communications for multiple agencies, improving emergency response times and fostering inter-agency cooperation, which stakeholders viewed as a successful deployment rather than a mere test. The AUSCI project in Minneapolis aimed to optimize traffic signals using the SCOOT algorithm, with testing scheduled to evaluate system performance and costs. Collectively, these summaries illustrate the diverse applications of ITS technologies, ranging from real-time traffic data collection and commercial vehicle efficiency to rural resource coordination, providing evidence-based insights into the feasibility, user acceptance, and operational impacts of these systems.
