Wait Time, Fault Display System
Displays Real-Time Messages to Motorists
The Wait Time / Fault Display System (WTFDS) provides drivers with a visual representation of the amount of time remaining before the next green indication. It is also configured to display a special message in the event of a signal error or fault, alerting drivers how to proceed, or to seek an alternate route.
The WTFDS’s primary application is one-lane, bi-directional work zones utilizing Horizon Signal SQ3TS systems. Consisting of only a variable message sign, and a simple connection to the Horizon PTS, the system provides a convenient and easy way to communicate with motorists.
How it Works
When the Horizon Portable Traffic Signal displays a red indication, the Changeable Message Sign (CMS) displays the remaining red time in minutes/ seconds. When the signal display changes to green, the CMS displays a “Slow Work Zone” message.
On a yellow indication, the CMS displays a “# minutes (or seconds)
wait time” message. All messages may be customized to meet
The WTFDS is available in two different sizes, and can also be
upgraded to allow for remote access to the signal messages.
