Traffic Calming Studies


Radar Speed Signs

Radar Speed Signs, also known as Driver Feedback signs are some of the most effective traffic calming products out there. They have virtually no disadvantages and provide lasting results. Other measures, like speed bumps and curb adjustments (bump outs, lane narrowing, etc), oftentimes pose problems to larger vehicles like school buses and emergency response vehicles like fire engines, and also cost municipalities money in damages to snow removal equipment. Dynamic radar signs have no negative impact on traffic lanes, and prompt drivers to voluntarily adjust their speeds to match posted limits.

Why Regulating Speed Matters

Several studies and reports can attest to the importance of the role that speed plays in factoring into roadway safety. As every driver is aware, higher traveling speeds require longer time and distance to slow to a stop. This personal experience sometimes fails to convey the critical importance of speed limits in residential and work zone areas. In these locations, lower speeds are necessary to give the driver sufficient time to react to unexpected events (such as children darting into the road, or a worker falling into traffic). When drivers exceed posted limits, the risks of fatal collisions increase exponentially. Even an alert driver who is focused on the road can be involved in accidents when not observing the speed limit. When it comes to driving safety, vigilance is only effective when coupled with caution.

When drivers speed, they pose a threat to themselves and everyone else on the road, pedestrians and other motorists alike. One third of all fatal collisions are deadly because of excessive speed. Speeding is the second most deadly factor in car-related deaths, second only alcohol intoxication.

So Where Do Driver Feedback Signs Come In?

A survey of several law enforcement officials polled participants on their opinions and preferences for various types of traffic calming solutions. Many stated that the display speed signs required little maintenance and kept up effectiveness over an extended period of time, unlike the temporary effects of, for example, police patrols of a problematic area. By far, driver feedback radar signs are the most effective and easiest to implement, based on anecdotal evidence. However, several studies have categorically shown the effectiveness of dynamic feedback signs, even over other common traffic calming measures. Speed bumps, lane narrowing, and curb alterations slow traffic, but they also make it difficult for emergency vehicles, snow plows, and school buses to navigate through urban and residential areas.

Driver feedback signs encourage drivers to adhere to the speed limit without requiring extensive curb alterations, extended use of police force labor and resources, or restricting road access.
