Traffic signal controllers are the workhouse of signalized intersections. Based on open standards and built on a Linux platform, the XN Controller is part of Q-Free’s ATC Controller line (advanced transportation controllers) – ideal for the new connected, data-rich landscape of traffic signal operations.

An oversized 128 x 256 pixel OLED display makes programming a breeze and improves visibility in direct sunlight, no sunlight, and everything in between.

The XN architecture not only organizes and improves traffic signal operations, it refines app integration allowing you to run multiple applications on the same device and reduce the amount of equipment in your traffic control cabinets.

Integrations our customers love include:

  • Managing Ethernet traffic
  • Monitoring detection devices
  • Integrating with third-party devices
