Portable Traffic Signals

Portable Traffic Signals are equipped with an internal conflict monitor, or Malfunction Management System (MMS).

Portable Traffic Signals are equipped with an internal conflict monitor, or Malfunction Management System (MMS). This feature is exclusive to Horizon Portable Traffic Signals and provides redundancy within each signal network. By monitoring for malfunctions at each trailer within the network, we eliminate the possibility of an MMS failure leaving the signal system without the ability to detect malfunctions. The MMS, combined with an intuitive programming interface, makes this control system the most advanced operating system in the industry.
