US-based software solutions company Iteris has secured funding from the Federal Highway Administration (FHWA) for the intelligent transportation systems (ITS) reference architecture programme.

Under the agreement, Iteris will continue to support the evolution of the architecture reference for cooperative and intelligent transportation (ARC-IT) content to reflect changes in ITS and developments in connected and automated vehicles (CAVs).

The company will provide state-wide and regional ITS planning and deployment to encourage interoperability and CAV preparedness through workshops, training and technical assistance.

The ITS programme, which Iteris has been working on for more than 30 years, focuses on alignment with and support for standards development activities, in addition to international coordination of ITS architecture and standards concepts and approaches.

Iteris secured the $3.15m funding for a task order under its indefinite-delivery/indefinite-quantity (IDIQ) contract.

The funding will be added to an existing three-year task order agreement, which began in November and is part of a five-year IDIQ contract with a contract ceiling of up to $19.5m.

Iteris Consulting Solutions federal and research programmes vice-president Cliff Heise said: “We are pleased to announce the FHWA’s additional funding of Iteris’ continued development, evolution and deployment support for ARC-IT.

“As connected and automated vehicle technologies become more advanced, it is vital that the US continues to invest in preparations for the new realities that will be enhancing safety and mobility going into the next decade.”

Last week, Iteris was awarded an ITS and traffic signal synchronisation contract by the Illinois Department of Transportation (IDOT).

The $500,000 project will involve modifying and modernising existing traffic signals with advanced traffic signal systems, as well as signal coordination and timing (SCAT) improvements at key signalised junctions.
