The novel speed bump from badennova is designed to respond to the speed of the vehicle crossing it

Spanish firm 7404 badennova is now offering a novel alternative to conventional speed bumps. This innovative system can be designed to a particular vehicle speed and features a soft, deformable exterior, with a viscous liquid inside.

When a vehicle drives over the bump at a speed below its rating, the bump deforms so as to minimise the shock. However, should a vehicle drive over the bump in excess of the speed rating, the liquid will not allow rapid deformation and transfers its shock to the vehicle. The first of these units has been tested over a five-year period successfully and the products are now being installed for use in indoor parking areas. A new version that can be used in outside applications will be available at the end of 2013, using a liquid with a viscosity that does not change along with increases or falls in temperature.

Because the speed bump deforms when driven over at the intended limit for the route, it offers additional advantages also. As long as the driver remains at or below the posted speed limit, there is no risk of damage to a vehicle and the unit will also not damage low-slung performance cars that can be vulnerable to conventional speed bumps. There is also reduced noise in use and no risk of damage to the roadway behind the speed bump from heavy vehicles.

In addition, the firm is working on a post protection system for crash barriers. This is designed to meet Spanish requirements for protecting motorcyclists from injuries from barrier support posts. The barrier protection system uses much of the same technology developed for the speed bump. However unlike the speed bump, the design has been configured so that the product becomes more shock absorbent with speed. This helps protect a fallen rider in the event of a potential impact.

    Familiarly known as “speed cameras” to motorists around the world, automated speed enforcement (ASE) devices produce a record of the speed of a vehicle when the driver has exceeded the acceptable maximum limit. However, as recently publicised cases have shown, for an ASE system to be effective and widely accepted, it is of paramount importance that all readings from these devices are accurate, and that this accuracy can be proven by those operating the devices.

    Safety and autonomous vehicles exercised the minds of some of Europe’s senior police officers at the recent TISPOL European Traffic Police Network Conference in the UK. The European Union looks like missing its target of halving the number of people killed on its roads each year by 2020. Just when European police forces are trying to get back on target, along comes the autonomous vehicle with all its inherent safety issues.
