Telematics - Intelligent transport systems (ITS) – Vehicle-infrastructure interaction and cooperation

Society yearns for safer, smoother and cleaner traffic. The decrease in public investments, coupled with these justified social expectations, is underlining the need for new answers to the traditional challenges. Road managers and operators are currently working towards a culture of network optimization. These various factors are at the core of the exponential growth of intelligent transport systems (ITS).
BRRC contributes to this area by collecting and disseminating information. A good knowledge of the potential of ITS as an alternative to more traditional, more physical methods, is essential for decision-makers and road planners. These systems, which come in various forms and formats, are intended for the road network as a whole, from motorways to municipal roads.

BRRC as a sectoral operator for CEN/TCs 226 Road equipment, 227 Road materials and 396 Earthworks

Le 20 mars 2007, le conseil d’administration du Bureau de Normalisation (NBN) a reconnu notre centre de recherche en tant qu’opérateur sectoriel pour les comités techniques européens CEN/TC226 Equipements de la route et CEN/TC227 Matériaux routiers.

Fin 2009, le CRR, conjointement avec le CSTC, a été accepté en tant qu’opérateur sectoriel pour le tout nouveau CEN/TC396 Terrassements.


Item 241-01 HERMES – Harmonization of European Routine and research Measuring Equipment for Skid Resistance

HERMESHarmonization of European Routine and research Measuring Equipment for Skid Resistance was a FEHRL-funded pre-normative project that aimed to lay the foundations for consistent European standardization of skid resistance measurement on roads and runways. Underlying the work was the idea that the project should give the initial impetus to the implementation of a common scale of friction, the so-called EFI (European Friction Index), together with an associated harmonized calibration procedure, in all European countries.

Measurement of the nighttime visibility (retroreflection) of road markings in dry weather (RL)

Areas of Expertise (1)


La visibilité de nuit est l’intensité lumineuse perçue par un automobiliste à 30 m provenant d’une unité de surface du marquage échantillonné et par une unité d’intensité lumineuse du marquage, lorsque ce marquage est éclairé par le rayon lumineux oblique des phares du véhicule. La visibilité de nuit est, tout comme celle de jour, exprimée en mcd lx-1 m-2. Les cahiers des charges exigent des marquages neufs des rétroréflexions situées entre 100 et 300 mcd lx-1 m-2 pour les marquages blancs et entre 80 et 200 mcd lx-1 m-2 pour les jaunes. Certains marquages blancs présentent des rétroréflexions initiales de 500 mcd lx-1 m-2 et plus. L’appareillage de mesure dont dispose le CRR est un RL2000 de la firme DELTA et est décrit dans la fiche d’information CRR F56.


European project INTRO (INTelligent ROads) (FEHRL)

The objective of the European project INTRO (Intelligent Roads)was to demonstrate that an efficient application of present information and communication technologies could bring “intelligence” to roads and offers unique opportunities to better manage and maintain the road
