Each year in the States, large numbers of road construction employees are struck and mortally injured. Speeding traffic near roadside construction sites is still an issue that state DOTs spend massive amounts of time and money attempting to fix.
When struck by a vehicle traveling at 40 mph, only 1 out of 10 pedestrians will survive. But at 30 mph, 5 out of 10 pedestrians will survive collisions. The requirement for effective speed enforcement at work areas is clear.
There is a solution, though. Variable speed limit (VSL) signs have been shown to be effective at improving speed limit compliance and speed awareness better and for longer than most other techniques. Reasonable and simple to set up, a TraffiCalm variable speed sign will help reduce traffic speeds near roadside work sections.
How the Speed Limit Sign Can Help
Radar speed signs are versatile. They may be employed to alert drivers of dangerous road conditions, to improve traffic flow during high-congestion hours, to enhance work sector safety, and to conduct traffic information collection.
More than that, though, VSL signs have been demonstrated to be effective at improving speed limit compliance in work sectors, which dramatically increases work section safety for drivers and staff alike. Utah's Dept of Transportation commissioned some research to test the effectiveness of VSL signs at slowing traffic near roadway construction areas.
Protect Roadside Workers with These Signs
The Utah DOT placed one or two traffic counters along a stretch of highway undergoing construction for a number of months. The UDOT discovered that one of the best benefits of the programmable VSL sign was the facility to turn it on only in occassions when construction was actively happening. Normal highway traffic speeds were allowed to continue unhindered when construction crews weren't present. When the work zone was active, the VSL sign caused drivers to slow down better than a static sign.
