Variable Message Signs
Communicate real-time information clearly and efficiently. In a smart work zone, variable message signs automatically display preset messages based on data gathered from traffic sensors and other sources.
For example, a message sign can warn drivers of stopped traffic ahead, of an upcoming merge point, suggest an alternate route option, or more.
Speed Signs
In a smart work zone, the speed limit can automatically lower based on if a work zone is active or not. One of the ways this can be detected is if workers wearing connected vests are present on the site. The speed limit then lowers to protect workers from high-speed traffic.
