The overall goal of this project was to evaluate the efficacy of dedicated short-range communications (DSRC) in improving efficiency and safety within a network of signalized intersections. This communication system is now being transitioned to CV2X frequency.
In this project, we developed the data collection, processing, and analysis mechanisms for traffic state data collected from the Gainesville Trapezium, a set of high-volume arterials surrounding the University of Florida in the City of Gainesville. The Trapezium is instrumented with various sensing equipment, including high-resolution loop detectors, video cameras, DSRC roadside, and vehicles with on-board units.
We developed an automated system for the data collection and setup a processing software architecture, consisting of edge computation, local servers, and cloud-based components that we use to deploy our applications. We conducted a “before-after” study to determine the efficacy of the deployed DSRC system. We interviewed drivers of vehicles with on-board units to learn about their experience with the system. We also discuss the impact of COVID-19 pandemic-related closures on the state of traffic on the Trapezium, which occurred during the duration of this project.
