A Look at the Modern-Day Cabinet

1976 marked a big year for technology. This was the year the Apple I computer debuted and the first traffic standard was published. Like Apple computers, the traffic cabinet has evolved to better incorporate modern technology, however, it wasn't until recent years that the traffic cabinet saw huge advancements. 

Combining existing standards and the latest technology, the design and deployment of the ATC cabinet has proven to be a modern milestone in traffic cabinet history. In this month's issue of The Source we take a closer look at the revolutionary cabinet, its modern features, and how one agency is benefiting.
Anatomy of the ATC Cabinet
Key features and components of the ATC cabinet.

Like a computer, a traffic cabinet is made up of many components that run and operate an intersection. The ATC cabinet design uses the best parts of the NEMA and Caltrans style cabinets in conjunction with new, state-of-the-art components, creating a traffic cabinet worthy of our technologically advanced generation.

Here are a few of the big changes the ATC cabinet offers:

Cabinet Monitor Unit (CMU)
Eliminates load switch leakage, simplifies cabinet troubleshooting and LED signal head circuitry. 

Flasher Transfer Relay (FTR)
Offers more reliability thanks to the airtight, hermetically sealed enclosure. FTRs of the past are prone to attract insects, therefore decreasing reliability. 

Switch Pack
Operates at the equivalent to two switch packs found in NEMA and Caltrans cabinets and at half the physical size.

These smaller and safer components help create a single platform for all applications; therefore, no longer forcing agencies to use multiple cabinets for multi-use function.

Another advancement found in the ATC cabinet is the protection against high-voltage components (50V+). Per NEC guidelines, all high-voltage components are unexposed, safeguarding users against accidental contact while decreasing liability and the high cost of cumbersome safety gear. 

ATC Cabinet Case Study
Location: Cedar Park, Texas.

In theory, the ATC cabinet sounds like a good option, but what are the benefits seen from implementing this technology? The city of Cedar Park realized those benefits first-hand after deploying the ATC cabinet.

PROBLEM: Cedar Park, Texas was looking for a solution to curb congestion and improve traffic in its growing city. 

SOLUTION: As technology enthusiasts, city leaders believe in leveraging cutting-edge intelligent transportation devices to enhance mobility, connectivity, and accessibility. All solutions pointed to the ATC cabinet. 

RESULTS: With numerous deployments of McCain's ATC cabinet throughout the city, Cedar Park realized the following benefits:

More power.
The ATC cabinet combined with McCain's ATC eX 2070 controllers, powered by Omni eX® intersection control software, equipped each intersection with added power to tackle sophisticated operations and control.

Less inventory.
The streamlined design of the ATC cabinet coupled with the use of high-density, multipurpose components, drastically cut inventory requirements, saving the city money.

Easier to maintain.
Front and back cabinet doors make it easy for technicians to access and maintain cabinet components and equipment. Plus, less cabinet components means fewer parts for technicians to troubleshoot.
