Intelligent Network Flow Optimization (INFLO) Prototype Seattle Small-Scale Demonstration Report

This report describes the performance and results of the Intelligent Network Flow Optimization (INFLO) Prototype Small-Scale Demonstration. The purpose of the Small-Scale Demonstration was to deploy the INFLO Prototype System to demonstrate its functionality and performance in an operational traffic environment and to capture data that can help assess hypotheses pertaining to system functionality, system performance, algorithm performance and driver feedback. In this Small-Scale Demonstration, Battelle and Texas A&M Transportation Institute (TTI) worked with Washington State Department of Transportation (WSDOT) to deploy connected vehicle systems in 21 vehicles in a scripted driving scenario circuiting a corridor on I-5 from Tukwila to Edmonds through downtown Seattle, during morning rush hour the week of January 12, 2015. The INFLO Prototype System collected vehicle speed data from both the WSDOT infrastructure-based speed detectors and the connected vehicles during the driving scenario. The System processed the data in real time and delivered queue warning and speed harmonization messages to drivers. The Team captured performance data as well as driver feedback. The Small-Scale Demonstration fully confirmed the functionality of the INFLO Prototype System using both cellular communications and dedicated short-range communications (DSRC). The Demonstration confirmed that the System has the latency, processing speed and communications bandwidth to support INFLO application functionality in an operational traffic environment.
