TraffiCalm has put its innovative driver feedback sign technology into a variable speed sign. These signs offer affordability, straightforwardness of programming, on-site and real-time traffic data collection, immediate effectiveness, and long-term speed reduction.
Improve work zone safety, alert drivers of threatening road conditions, and make school zones safer. The variable speed sign is proven effective at inspiring speed limit compliance in speed transition sections, work sections, and more risky traffic areas.
Variable speed limit (VSL) signs are designed to show the speed limit to drivers. TraffiCalm's VSL signs can be set up to discourage speeders by flashing the limit or a strobe light when it detects speed violations. Different speed limits can be programmed via a fixed schedule or the convenient Bluetooth connection.
In 2008, the Utah Department of Traffic (DOT) commissioned an analysis to test the usefulness of variable speed limit signs at improving speed compliance. They placed a few traffic counters, which recorded traffic volume as well as speed, at key intervals along a stretch of highway for several months. They installed two VSL signs with programmed schedules, based primarily on week and/or time of the day or night.
In a three month comparison between a static speed limit sign (65 miles per hour), a VSL sign (65 miles per hour), and a second VSL sign (55 mph during the day, 65 miles per hour at night), it was determined the static speed limit signs were the least useful in reducing speed excesses.
The static signs constantly had the greatest number and best standard deviations from the posted speed limit, while the variable speed signs caught driver attention and inspired speed compliance, even when the signs instructed drivers to reduce their speed to 55 miles per hour (in contrast to the remainder of the highway's 65 mph limit).
Variable speed signs are the most useful means of promoting highway safety for drivers and pedestrians. Crash rates are reduced when rates of speeding are reduced. Survival rates increase as speed decreases.
