Iteris has secured a contract from the US-based transit agency Alameda-Contra Costa Transit District (AC Transit) to provide design services for a corridor project to cut travel times.

The project works include implementation of real-time passenger information system, transit signal priority (TSP), bus stop improvements, and deployment of an adaptive signal control technology system. 

With the new $934,000 contract, AC Transit has further involved Iteris for improving Line 97, which covers a distance of 12.5 miles and comprises some of the major corridors in the San Francisco Bay Area. 

TSP tool has been designed to reduce delays and improve schedule reliability for transit operations. 

Currently, the service time for Line 97 is approximately 134 minutes, and upon completion of this project, the roundtrip travel time is expected to be reduced by nearly 15%. 

"Upgrading the corridor transportation technology infrastructure will produce cascading benefits that include improvements to signal operations."

Iteris Transportation Systems general manager and senior vice-president Ramin Massoumi said: "This project will improve transit operations and the overall transit customer experience by reducing traffic congestion and improving intersection efficiencies along Line 97. 

"Upgrading the corridor transportation technology infrastructure will produce cascading benefits that include improvements to signal operations, resulting in reduced fuel consumption and vehicle emissions, ridership growth through improved schedule reliability, and improved air quality.

"These benefits and goals are consistent with AC Transit’s strategy to maximise operational benefit and efficiency and achieve the San Francisco Bay area’s Transit Sustainability Project performance metrics.”

Iteris has provided transit signal operations for more than 30 agencies covering over 1,000 intersections nationwide, is currently involved in similar transit projects in Los Angeles, Chicago, Minneapolis, and Orange County, California."
