About one fifth of all traffic accidents in Belgium are collisions with obstacles off the carriageway. Generally a single vehicle is involved in these.
However, there is a considerable difference in severity of the consequences of such accidents. The risk of death after a collision with an obstacle off the carriageway is at least twice as high as the average risk of being killed in a traffic accident. And the risk of serious injuries is still at least 60 % higher than on average.

Space – Speed Adaption Control by Self-Explaining Roads

The objective of the SPACE project was to identify solutions that offer the greatest potential safety gains. A literature review was made for that purpose, and a panel of experts evaluated a number of promising treatments by means of interactive visual tools and through experiments in a driving simulator.

Skid resistance / Slipperiness

Skid resistance is defined as the frictional resistance at the interface between a vehicle tyre and the road surface. It plays an important part in the safety of road users: a correlation has been demonstrated between the skid resistance of pavements and accident rates (see the diagram opposite) [of course, there are many other possible causes of accidents: human error, vehicle technical failure, weather conditions, other infrastructure-related factors, etc.]. Wet pavement skid resistance is considered here, since dry pavement skid resistance is rarely a problem. A rough contact between the road and the tyres makes it possible to utilize the friction forces in braking. These friction forces also allow easier cornering. As a result, it is obvious that road managers should pay much attention to skid resisistance and alert road users in time of any local problem with poor skid resistance, and also that they should replace the pavement as soon as possible by an adequately skid-resistant pavement.

Standards support office (“NAN”)

With support from the Belgian Federal Public Service Economy, SMEs, Middle Classes and Energy, BRRC operates a standards support office that goes by the acronym “NAN”. The object is to inform SMEs in the road branch and make them aware of developments in the field of standardization and, where necessary, to offer them additional support in implementing new standards (which are often mandatory).

Road Equipment Commission (REC-E226)

The publication of the European Construction Product Directive in 1989 marked the beginning of the gradual introduction of European standardization. European standards are to replace existing Belgian standards, or at least require them to be thoroughly revised. By affixing a CE mark, the manufacturer declares that the performance characteristics of his product have been determined by the appropriate European standard and that measures have been taken for the product to continue meeting these declared characteristics.

As the actors in the road equipment branch were concerned about the impact of this European standardization, a steering committee on European standardization in the road equipment branch was formed at BRRC in the spring of 2003. The first task of this committee was to increase the awareness of, and disseminate information to, the various actors in the field: road authorities, manufacturers, specialized institutions, etc. For that purpose, a series of thematic sessions on the standardization and CE marking of road equipment was held in March 2004.
