Many of us are most likely to slow down, whether or not we aren't speeding, when we see a police squad car. That is just survival instinct, since law enforcement officials do monitor traffic speed with radar. The majority of people probably feel like that the police are monitoring the velocity around them at each turn. So why do dynamic signs work better at reducing speed than law enforcement?
One reason may be that the law enforcement is not always seen, while the signs are lit up and bright, making them simple to spot. Another reason could be that many drivers believe they probably won't get picked out by law enforcement for speeding if they are in a group going the same speed or even higher speeds.
With a flashing sign that is giving info directly related to each driver, it'd appear more likely that a person could be ticketed for speeding. Whatever the explanations, traffic signs were thought by a group of traffic experts and law enforcement to work better in a 2008 study.
Rumble strips are strips usually on the shoulder which make the automobile vibrate when the tires roll over them. These could be a good option to bring somebody's attention to where they're driving, to tell them they're off the side of the lane. Somebody dozing off and curving to one side, for example, may be woken by a strip's vibration. Somebody simply not concentrating and sliding to one side or the other could become conscious of the road, too. As speed control, they were presumed far less effective than a driver feedback sign.
Speed bumps were another choice. An ambulance or law enforcement vehicle that has to rush to pick up somebody ill will be forced to slow or discover a way around those bumps. Radar signs, though, don't affect the vehicles' movement in any fashion.
