The city of Dublin moved one step ahead by installing connected vehicle technology at two intersections and on two fleet vehicles. The installation of this technology will strike a stepping stone in the deployment of intelligent transportation infrastructure. The project is a part of 33 Smart Mobility Corridor project and partially funded by a U.S. Department of Transportation (USDOT). Earlier this technology was implemented at Marysville’s 35-miles long highway and 27 traffic signals and tested around 1200 vehicles.
Vehicles will be equipped on-board units (OBU) capable of syncing with other vehicles, traffic lights, roadside signals, and crosswalks equipped with road-side units (RSU). The RSU and OBU devices are capable of receiving and broadcasting messages using Dedicated Short Range Communications (DSRC), which involve vehicle-to-vehicle and vehicle-to-infrastructure communications.
The data of the vehicles will be collected anonymously and imparted to the traffic management centers in real-time. This transmission will not only increase efficiency but will also predict the traffic pattern, improve the flow of traffic along enhanced safety. For instance, if a driver is stuck in black ice, the vehicle will issue an alert to the traffic management center, who will dispatch the concerned authorities to rescue the stuck vehicle and driver.
U.S. Department of Transportation (USDOT) awarded the grant of $5.9 million to the City of Dublin, the City of Marysville, and Union County in 2016. The purpose of this grant was to fund the DSRC infrastructure installation along the corridor for connected vehicle and autonomous vehicle testing and research.
