NEMA to Develop Standards for V2I Communications
Vehicle-to-Infrastructure Standards designed to accelerate deployment of traffic control devices that communicate with vehicles
April 22, 2019

The National Electrical Manufacturers Association (NEMA) today announced the formation of the Connected Vehicle Infrastructure Technical (CVIT) Committee to develop a harmonized technical specification for roadside connected vehicle (CV) devices.

The Standards, to be completed by the end of 2019, are for traffic signals, school zone beacons, pedestrian crossings, and other electronic devices that control the movement of vehicles and pedestrians on the nation’s roadways. The ability to transmit safety messages, alerts and warnings from the infrastructure to vehicles and vice versa, is a critical function of CV technology.

“This working group will create the Standards that will give state and local agencies that operate and maintain roadways the confidence to deploy connected vehicle infrastructure to cover the nation and advance this critical safety feature,” said Bryan Mulligan, NEMA Transportation Management Systems and Associated Control Devices Section Chairman and President of Applied Information, Inc. “To be successful, the connected vehicle infrastructure must be interoperable, future proof, reliable, and maintainable by local agencies.”

“A key component of the connected vehicle ecosystem is the ability for vehicles and the infrastructure to communicate with each other regardless of the type of device or underlying technology,” said Steve Griffith, NEMA Transportation Industry Director. “This Standard will provide a mechanism to ensure this critical function is carried out across the industry.”

The need for Standards and formation of the CVIT Committee is the result of an industry workshop on connected vehicle infrastructure hosted by NEMA. The workshop was attended by thought leaders from the semiconductor industry, intelligent transportation technology providers, traffic technology manufacturers, and infrastructure contractors and installers.

The workshop demonstrated a need for developing a harmonized technical specification for roadside CV devices that include practical agency customer needs including maintainability, connectivity, communications interoperability, over-the-air software updates, and the ability to address future advances in communications technology.
