Actibump road safety technology slows down speeders

More info here http://www.edeva.se/en/#actibump

The purpose of a traffic-calming installation is to cause road traffic to reduce speed and in this way reduce the risks for other road users. The speed of a vehicle approaching the Actibump is recorded with the aid of radar measurement. No action is taken if the vehicle speed is within the legal limit, but if it is approaching faster than is permitted, a part of the roadway pivots downwards, creating an edge.
