Abstract

Dynamic speed feedback sign (DSFS) systems are traffic control devices that are programmed to provide a message to drivers exceeding a certain speed thresh­old. A DSFS system typically consists of a speed-measuring device, which may be loop detectors or radar, and a message sign that displays feedback to drivers who exceed a predetermined speed threshold. The feedback may be the driv­er’s actual speed, a message like “SLOW DOWN,” or activation of a warning de­vice such as beacons or a curve warning sign.
