ENERGY ABSORBING MATERIALS AND STRUCTURE IN THE FUTURE DESIGN OF THE ROAD SAFETY EQUIPMENT

It is an obvious fact that road traffic participants will always make errors. These errors have generally resulted in traffic accidents. While the majority of automobile crashes involve vehicle-to-vehicle impacts, a number of traffic incidents involve vehicles impacting roadside equipment. Existing roadside equipment are designed to maximize performance and minimize cost. However, there are still many fatalities and serious injuries on the roads. Leading EU countries have recognized the need for passive safety improvement of roadside equipment as an important step to achieving reduction of serious occupant injuries. The improvement of existing roadside equipment and the future development of new structures, as well as the testing methods is of high importance for everyone who deals with road traffic problems. Devastating injury statistic of traffic road accidents with car – roadside structure collision requires continuing research which should lead to improved roadside equipment. The automotive industry makes great effort to meet more and more rigid norms for the occupant passive safety. These efforts will be fully expressed only with parallel development of roadside equipment. On 23rd of September 2007 the European Committee for Standardization (CEN) approved the new EN 12767. Roadside equipment must be designed in the manner to meet the requirements of EN 12767. The aim of this article is to point out that in the “road traffic world” there is a constant need for research in the field of roadside equipment, with the main purpose to improve of traffic passive safety. The improvements as, usage of energy absorbing materials and structures in the roadside equipment, will insure more favorable decelerations during a crash/accident resulting in less injury for the car occupants.
