Maine Turnpike Authority (MTA) has selected and begun deploying Econolite’s advanced traffic controller cabinet (ATCC).
The tolling agency has gone for the 48-volt option that enables the use of alternate power sources and longer-lasting battery back-up systems.
Econolite says this is a "critical safety feature for inclement weather conditions that can interrupt utility power".
The manufacturer suggests it is also a greener option since it takes less power to operate.
Maine Department of Transportation adopted the ATCC as the state standard in 2019.
“The expansion of capabilities and options the Econolite ATCC provides makes it ideal in support of our infrastructure modernisation program,” said Eric Barnes, P.E., MTA toll system/ITS manager.
The ATCC supports both 120 VAC and 48-volt DC signal heads, while high-density load switches and quad detector modules allow for up to 32 signal outputs and 120 detection inputs.
This means MTA can use more intelligent traffic controllers and sensors, insists Barnes.
The Econolite ATCC is built to meet and exceed the ATC 5301 V02 Advanced Transportation Controller Cabinet Standard.
Design is based on Safetran’s Caltrans, NEMA, and ITS cabinets.
