Raised traffic calming devices

The royal decrees of 9th October 1998 and 3rd May 2002 on road humps lay down the requirements and technical specifications to be met by these devices. BRRC has developed for the geometric inspection of “raised traffic calming devices on public highways”, as they are officially named, a method of measurement which allows rapid assessment of their compliance with requirements and specifications.
The law authorizes traffic calming devices with varying geometries and dimensions, but requires that they should be adapted to local circumstances (location, types of vehicle in traffic). As a result, not all specified devices (and, all the more so, those failing to comply with regulations) have the same intrinsic effectiveness in reducing speeds. That is why the choice of a traffic calming device with any ensuing layouts or facilities requires careful reflection on the objectives to be met. To collect objective input for this reflection, the Centre also makes measurements on existing sites, where both geometric data and travel speeds are recorded.


Construction Products Regulation and role of the declaration of performance

Construction Products Regulation (CPR) (EU) No 305/2011 has been fully applicable since 1st July 2013. It has definitively replaced Construction Products Directive (CPD) 89/106/EEC. With this new regulation the European Commission (EC) intends to clear up a number of persistent misunderstandings arising mainly from confusion with other directives which also underlie CE marking.


Speed control by improving road legibility – Self-explaining road concepts

It is generally accepted that human error is involved in a good many road accidents. Although education, awareness and enforcement are important tools in reducing the number of accidents, it is equally crucial that the road environment and the vehicle should be adapted to the limitations of human abilities.
