Abstract: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 Speed Harmonization (SPD-HARM) and Queue Warning (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.
The demonstration proved connected vehicle data capture and dissemination functionality using both cellular
communications and DSRC communications. 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.
