A three-year project aims to improve traffic flow and safety across eight southern California cities using technology from local company Iteris.

The programme includes Iteris’ intersection-as-a-service offering, which provides proactive signal operations and maintenance with round-the-clock monitoring of device and system health.

This is a $4.7m initiative from the Orange County Transportation Authority (OCTA) for a regional traffic signal synchronisation project. It includes signal coordination and timing improvements, with the aim of improving traffic flow, enhancing public safety and decreasing stops.

Iteris will upgrade traffic signal electronics and communications equipment, and optimise signal timing along Katella Avenue, a major east-west corridor that comprises key signalised intersections spanning the eight cities of Anaheim, Orange, Garden Grove, Villa Park, Cypress, Los Alamitos, Stanton and County of Orange in Orange County, California.

In January this year, Iteris was awarded a $3.6m contract to perform the same services across Orange County’s Main Street corridor.

The intersection-as-a-service offering is part of the firm’s ClearMobility platform. It can deliver proactive monitoring of traffic signal operations at all project intersections. The primary goal is to deploy intelligent transportation system (ITS) equipment and communications infrastructure to support the management of the cities’ transportation network, implement optimised coordination timing plans to achieve optimal traffic flow, and improve safety for all road users, including vehicles, buses, bicycles and pedestrians.

“We are proud to support OCTA’s goal of improving the safety and mobility of road users by embarking on this traffic signal synchronisation project,” said Scott Carlson, vice president at Iteris. “This initiative represents the continued expansion of Iteris’ traffic signal coordination services, as well as our intersection-as-a-service offering, across the west coast and will ultimately help to increase the value and effectiveness of the region’s existing transportation infrastructure, while also improving air quality and reducing fuel consumption.”

ClearMobility can continuously monitor, visualise and optimise mobility infrastructure. It applies cloud computing, artificial intelligence, sensors, advisory services and managed services to help ensure roads are safe and travel is efficient.
