Actibump

Actibump is a traffic safety system where speeding vehicles activate an inverted speed bump integrated into the road surface. It gives a physical reminder to speeding drivers. This is done by lowering a hatch a few centimeters into the road, creating a speed hump only for speeding vehicles. Actibump is a robust system that increases road safety and accessibility while lowering emissions and noise.[1] Actibump leaves the road level for vehicles driving at, or under, the legal speed limit.

Installations

The system is installed in several cities in Sweden, including Linköping, Uppsala, Västerås, Helsingborg, Malmö and on the Öresund Bridge. Currently, there are over 50 Actibump units active in the world. [2]

Actibump can be installed in heavily traffic roads where the speed limit is 5-60 km/h. The system can also be used at logistics centers, toll stations, airports, etc.

Effects

The Actibump system has shown through several independent evaluations that the average speed decreases, and also that the emissions and noise level decreases.[3]

gollark: In retrospect, it would make much more sense to handle it differently. I could edit it now, actually.
gollark: I tried to pack as much information as possible ~~without very much work~~ into the URLs, so they also support base64'd base256 encoded numbers (yes this is a mess) and (really poorly done) RLE on those.

gollark: Besides, it's much more efficient to use the RLE capability.
gollark: How is that an exploit?
