San Fran Adopts ATC Cabinets

San Francisco Selects McCain Inc. ATC Cabinets to Upgrade Traffic Signal Infrastructure

The 13^th largest department of transportation in the United States to create a smarter, more mobile city using ATC traffic cabinets from wholly-owned SWARCO subsidiary.

During the course of the contract, beginning in 2018 and lasting through 2021, McCain will deliver approximately 400 M ATC Cabinets (with the traditional M footprint of NEMA cabinets) as well as 140 Caltrans-style ATC cabinets, including the 352i ATC Cabinet and the 350i ATC Cabinet.

Traffic control cabinets house the computers and sensors which control traffic signal timing. Cabinets meeting the proposed ATC standard facilitate the movement of vehicles, people, and goods more safely and efficiently, while also providing a growth platform for operating in a connected and autonomous vehicle (CAV) environment.

McCain M ATC Cabinets combine the best of NEMA and Caltrans-style cabinets, using a rackmount design and leveraging existing M cabinet foundations to prevent costly sidewalk construction. Roozitalab said, “Busy cities like San Francisco need as much real estate as possible for pedestrians. Our M ATC Cabinet features two front side-by-side doors, ideal for areas with narrow sidewalks so maintenance teams can work inside without completely blocking the walkway.”

Using high-density ATC components, there is enough unused space inside the cabinet that San Francisco is planning to place a battery backup system (BBS) – a system that keeps intersections running in the event of a power outage – in the cabinet as well. This eliminates the need, expense, and space required to purchase and install additional cabinets to house the BBS. The energy-efficient M ATC Cabinet also has lower power requirements than most currently on the market, costing less money to operate over time.

“We’re looking to provide the very best services for our customers and we’re confident that the field-proven ATC technology will position us to be a smarter, more mobile city,” said Eddie Tsui, traffic signal shop manager for the City and County of San Francisco. “These cabinets are absolutely turnkey ready for us, and the support we receive on a continual basis will be crucial to the success of the project.” One key component for San Francisco choosing the M ATC Cabinet was its immediate “lamp out monitoring” algorithm. It is highly desirable to proactively identify an intersection with a dark signal approach and to effectively remedy the issue via maintenance which is achievable with the revolutionized ATC cabinet technology.

McCain pioneered the development of ATC cabinet technology and continues to lead the North American intelligent transportation system (ITS) industry with more than five times the deployments of its nearest competitor. Greg McKhann, chief operating officer for McCain, said, “We’re thrilled to provide an innovative city like San Francisco with ATC cabinets that meet their specifications. As an innovator in transportation, the ATC technology is just one of our many ITS solutions geared to improve the quality of life for communities by making the travel experience safer, more efficient, and environmentally kind.”
