Traffic and the Police Force

In research carried out to check which strategies reduced speed best in work areas, fake radar drones that were meant to set off police radar alarms were tested against other techniques like transportable rumble strips and radar speed display signs to see which slowed drivers down more.

Actually the signs not only caused the greatest speed reductions overall, they slowed down the biggest number of drivers.
