The City of Dublin has installed connected vehicle technology at two intersections, marking a significant step forward in the deployment of intelligent transportation infrastructure. This initiative is part of the 33 Smart Mobility Corridor project and partially funded by a U.S. Department of Transportation (USDOT) grant.
Roadside Units (RSUs) are now operational at the following intersections:
- Perimeter Loop Road & Avery-Muirfield Drive
- Perimeter Drive & Avery-Muirfield Drive
The RSUs will send real-time traffic signal phase and timing information to vehicles that are equipped with On-Board Units (OBUs). Long term, the OBUs will communicate with the RSUs sharing traffic information that will include location and speed of vehicles. This data will be processed to help transportation agencies measure traffic patterns and traffic flow from adjacent streets and intersections.
Drivers may notice the small RSUs posted at the intersections, but only vehicles with OBUs will communicate with the devices. Two City of Dublin vehicles are currently equipped with OBUs, with more OBU installations planned in the coming months. Eventually, all City vehicles will be equipped with the units.
While this initial phase of connected vehicle infrastructure deployment is limited, the long-term vision for this connected vehicle technology is much more robust.
“This is an important step for us here in Dublin, but it’s just the beginning,” says Dublin Public Works Director Megan O’Callaghan. “Ultimately, connected vehicle technology is designed to help improve traffic flow, efficiency and most importantly, safety.”
The RSU and OBU devices receive and broadcast messages using Dedicated Short Range Communications (DSRC), which involve vehicle-to-vehicle and vehicle-to-infrastructure communications.
“In the future, connected vehicles will transform our streets and help save lives by warning drivers of impending dangers, giving the driver time to take corrective action and potentially prevent a crash,” said O’Callaghan.
In 2016, USDOT awarded a $5.9 million grant to the City of Dublin, the City of Marysville and Union County for the advancement of the 33 Smart Mobility Corridor. Specifically, the grant provides funding for DSRC infrastructure installation along the corridor for connected vehicle and autonomous vehicle testing and research.
