Through the Dynamic Mobility Applications (DMA) Program, U.S. DOT desires to improve current operational practices and transform management of future surface transportation systems. The DMA program is designed to enhance deployment of the technologies and applications and promote collaboration in research and development (R&D) of the transformative mobility applications. The DMA program’s current phase involves application prototype development and testing and coordinated research activities on a portfolio of selected high-priority mobility applications. The Intelligent Network Flow Optimization (INFLO) bundle is one of these, a collection of high-priority, transformative applications that target maximizing roadway throughput, reducing crashes, and reducing fuel consumption through the use of frequently collected and rapidly disseminated multisource data drawn from wirelessly connected vehicles, travelers’ communication devices, and infrastructure. The U.S. DOT funded a Team led by Battelle and the Texas A&M Transportation Institute (TTI) (the Project Team) to prototype and demonstrate Dynamic Speed Harmonization (SPD-HARM) with Queue Warning (Q-WARN), two component applications of the INFLO bundle. In this program the U.S. DOT and the Team advanced SPD-HARM and Q-WARN from concept formulation to prototype development, acceptance testing and demonstration in a controlled environment. The team then deployed the applications in Seattle, WA to conduct a Small-Scale Demonstration to confirm its functionality and performance in an operational traffic environment. This Technical Report on Prototype Intelligent Network Flow Optimization (INFLO) Dynamic Speed Harmonization and Queue Warning is the final report for the project. It describes the prototyping, acceptance testing and small-scale demonstration of the INFLO Prototype SPD-HARM and Q-WARN applications. This report also describes the programmatic and technical accomplishments of the program wherein the Small-Scale Demonstration fully confirmed the functionality of the INFLO Prototype System in an operational highway traffic environment. The system was proven to reliably: *Capture current location and telematics data from connected vehicles and vehicle speed data from infrastructure; *Analyze the data to detect congestion and determine the beginning and end of congestion queues; *Formulate speed harmonization recommendations; *Communicate queue location and speed harmonization recommendations to drivers via in-vehicle systems. The demonstration proved connected vehicle data capture and dissemination functionality using both cellular communications and dedicated short-range communications (DSRC). Furthermore, the Small-Scale Demonstration confirmed that the INFLO Prototype System has the latency and processing speed to support INFLO application functionality in an operational traffic environment. This remainder of the report is organized into the following chapters: Chapter 2. Reference Documents; Chapter 3. INFLO Prototype System Design and Development Overview; Chapter 4. INFLO Prototype Component, System and Application Acceptance Testing; Chapter 5. INFLO Prototype Seattle Small-Scale Demonstration; Chapter 6. Summary of Accomplishments and Considerations for Future Work; and Appendix A. Acronyms and Abbreviations. (Author/publisher)
