Versatile traffic control cabinets built on an open architecture to support a variety of ITS applications and the future of connected and autonomous vehicles.

  • Improve safety for technicians and motorists alike
  • Manage complex intersections with ease

Advancing the latest trend in traffic signal control cabinets, Q-Free ATC Cabinets have all the features of traditional cabinets with a modern twist. Delivered in a flexible and functional form factor and ATC cabinets boost safety and efficiency, while laying the groundwork for a more connected tomorrow.
