A connected vehicle talks to other connected vehicles, roadside infrastructure (like traffic signals), and traffic management systems to keep the driver safe by providing information and warnings about their immediate driving environment. The driver remains in control at all times and receives warning messages via an audible tone or through images displayed on a screen. Connected vehicles provide drivers with an extended awareness of similarly equipped vehicles and infrastructure, and do not depend on line-of-sight communications to be effective. That is, a connected vehicle helps the driver by providing advanced warning about other vehicles or road conditions. For example, if a traffic queue was ahead of the driver but on the opposite side of a hill (that is, not visible), a notification will be sent to the driver giving them the time to slow down, if required.
Around 30 communication devices were installed on traffic signals at intersections throughout the pilot area. These devices have no impact on regular operation of traffic signals or vehicles that do not have connected vehicle technology installed.
The equipment installed into vehicles as part of the Ipswich Connected Vehicle Pilot included an antenna mounted on a roof-rack, an in-vehicle communications box placed under the driver’s seat, and a display on the dashboard that provided safety warnings to the driver.
Examples of the vehicle equipment used in the pilot:
In-vehicle display installed above the dashboard.
In-vehicle communications box installed under driver’s seat.
Roof rack with antenna installed on vehicle roof.
