The Nashville Department of Transportation and Multimodal Infrastructure (NDOT) has deployed ALCEA’s 75481 Series Traffic Cabinet Locks.
According to ALCEA, this has allowed the organization to transform the way Nashville protects its signal cabinets, Intelligent Traffic System (ITS) boxes and the technology that keeps traffic flowing safely.
ALCEA highlights that with tens of thousands of drivers, buses, cyclists and pedestrians moving through the city’s intersections each day, the smallest vulnerability inside a traffic cabinet, from unsecured doors to untracked contractor access, can pose risks to public safety.
“The truth is, we just didn’t have the security and control we needed before,” said Aaron Cushman, IT/ITS Division Manager for Nashville DOT.
“We needed to regain control in terms of who’s in our cabinets, when and why. That accountability piece was missing.”
The 75481 Series, powered by ABLOY technology, delivers high-security mechanical protection plus the electromechanical capability to generate full audit trails, manage permissions and provide real-time accountability for every keyholder, including city staff, field technicians, third-party contractors or timing study consultants.
“Key control and cabinet control. That’s really what this comes down to,” Cushman added.
“We want to be able to see who’s in our cabinets, when they’re in there and how long they stay. This system gives us that visibility.”
ALCEA says that the 75481 Series design is a practical fit for the city’s cabinet infrastructure.
Its drop-in installation means most locks can be swapped out in minutes without costly retrofits or new hardware, helping the city balance high security with responsible budgeting.
The program began in late July with an initial wave of installations to every signal cabinet in Nashville.
NDOT completed the upgrade of more than 1,000 intersections citywide in under 30 days.
