San Bernardino County Transportation Authority (SBCTA) has extended Iteris’ traffic signal synchronisation-related managed services contract across 16 municipalities in southern California, the US.

As per the 12-month on-call contract extension, Iteris will receive $737,000 in service orders under an existing $2.49m on-call contract.

Iteris will continue to provide on-call traffic signal synchronisation, as well as virtualise the agency’s processes, which will enable them to offer system support and maintenance services for the San Bernardino Valley Coordinated Traffic Signal System (SBVCTSS) corridors.

Covering more than 250 square miles, SBVCTSS corridors are said to form a heavily travelled arterial network.

The project aims to enhance safety for all road users, including vehicles, buses, bicycles and pedestrians.

In addition, the project is expected to reduce travel times, the number of stops, and carbon emissions along the SBVCTSS corridors.

As part of the new service orders, Iteris will be improving traffic signal timings, as well as performing ongoing traffic device and infrastructure maintenance for up to 1,250 signalised intersections across the 250-square-mile area.

The service orders will cover 16 agencies, including the Cities of Chino, Chino Hills, Colton, Fontana, Grand Terrace, Highland, Loma Linda, Montclair, Ontario, Rancho Cucamonga, Redlands, Rialto, San Bernardino, Upland, and Yucaipa, as well as the County of San Bernardino.

Using its ClearGuide software-as-a-service (SaaS) solution, Iteris will conduct before-and-after evaluations on all retimed corridors.

Iteris Transportation Systems regional vice-president Scott Carlson said: “We are proud to continue to support the SBCTA’s goal of improving safety and mobility in the San Bernardino Valley with this expansive traffic signal synchronisation program, which demonstrates growing demand for Iteris’ software-enabled managed services in southern California.

“The expansion of this initiative with the SBCTA will continue to decrease travel times and overall traffic congestion, as well as improve air quality and reduce the existing transportation system’s impact on the environment.”

Iteris said that it intends to commence the project immediately.
