Actibump Good or Bad?

[kikie]

I did a search hopefully, a good search and nothing came up.

The Actibump was developed in Sweden several years ago and a replacement for the speedbump.

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. Actibump leaves the road level for vehicles driving at, or under, the legal speed limit.

I believe the hatch lowers 6 cm into the road.

Wouldn't like to be a patient in an ambulance.

On the flip side, I'd love to own an alloy wheel repair place in that town. What a dreadful idea - why doesn't it have a smoothed exit gradient?

Emergency services have a remote device that shuts down the Actibump.

Sounds like a recipe for a grey-market product... Where's me soldering iron...

I like how it says that 2 wheeled vehicles can go round, shows a cyclist avoiding it, and then shows a motorcyclist going into it. Surely the motorcyclist can go round it too?

Surely there is a chance that someone is speeding so greatly that their wheel will crack or even shatter and cause a massive crash?

Also though when you are on a bike, trying to dodge it at last moment is going to send you flying anyway.


I think this is a terrible idea.

Bunny hop!

Given how simple and functional traditional speed bumps are, this seems like an expensive waste of time.

It lowers several inches into a sharp edge? That's absolutely insane.

Several cities in Great-Britain got this Actibump contraption. Be prepared to get your wheels cracked.
Germany is going to install these at the end of this year in Hanau.

What if an idiot installs the actibump backwards?

Wonder if they'll feel bad if a speeder hits one of these, loses control, and squishes some pedestrians?

[Dumb]

That'll be the speeder who's culpable.

What I wonder is who pays for the underground installation and the power to run them? The answer is the local council, which means it goes onto the Council Tax bill (if they were used in the UK). It would be far better spent on ANPR gates that issue speed tickets (producing a cash return for councils) and which will flag up cars with no insurance/MoT. It will also stop abuse by vehicles which have an override control fitted.

Actibump installation shows results


Trials in the city Linköping have shown the effectiveness of Edeva’s Actibump speeding deterrent. The average speed on the road, which is used by 5,000 vehicles per day, decreased from 36 to 32km/h following the installation of the device. Actibump comprises of a 6cm deep metal trough set in the road surface and utilises a roadside radar unit to monitor vehicle speed. If a speeding vehicle is detected the flat metal plate which normally covers the trough is activated and pivots downwards, exposing an edge which the vehicle bounces over.

The developers say the trough is deep enough for drivers to notice but will not damage the vehicle. Those obeying the speed limit pass the barrier unimpeded, helping to maintain a smooth traffic flow.

Actibump proves a success in Australia
In January 2018 Curtin University installed four active speed bumps called Actibump at the University’s campus in Perth, Western Australia.

The goal was to reduce the number of speeding drivers, particularly on semester week days when there are a lot of pedestrians and vehicles on campus. Mr Graham Arndt, Director of Operations and Maintenance at Curtin University, says: “We have been extremely impressed with the effectiveness of the Actibumps in reducing the number of speeding motorists along that section of road.

“The use of the smart speed bumps also provides a steadier flow of traffic, which makes it easier for pedestrians to judge the speed of the approaching vehicle, therefore making it safer to cross the road. Additionally, the units have been maintenance free and have operated continuously for a year without the need for any intervention.”

Because of this success, Curtin University is continuing to roll-out the Actibump systems across its campus in Perth, Western Australia. “We will be installing another set of two active speed bumps on Townsing Drive following the promising results we have witnessed from the new technology,” Mr Arndt says.

Another active speed bump will also be installed to replace a ‘dumb bump’, a moulded black plastic bump near the Manning Road entrance. Mr Arndt continued: “The old speed bump had prompted traffic to slow down to almost a stop, causing traffic to build-up near that entrance to the university. By using an Actibump at that location, we expect the traffic to flow more smoothly and within the speed limit, offering an effective road safety and traffic management solution.”

The success of the first internationally installed Actibump systems proves the system is efficient, not only in Sweden ...

I'm not sure WA is a good place to cite for sensible road safety policies. In WA, if you're more than 1km/h over the speed limit, you and the generation of your family either side of you is sent to a quarry gulag for 30 years, while if you're more than 3km/h over the speed limit the police are allowed to stop you with Hellfire missiles.

Mad Max.

From the article:

Speed limit and other variables are set through a web-based interface that also presents the statistics collected by the system.

Gonna be interesting when (not if) it gets hacked.
