After Seven Years RIMOB in Practice: An Evaluation of the Dutch Impact AttenuatorRIMOB

摘要

Since 1982 about 170 RIMOB impact attenuators have been installed on the mediansand shoulders of motorways in the Netherlands. The Dutch RIMOB is an impact attenuator with crumpling tubes to absorb the collision energy. The report is an evaluation study of the type of attenuator. There were three reasons to develop a specific impact attenuator for the Netherlands (European) market: (1) The wish of road authorities to apply a construction, capable to safely stop light and heavy cars. (2) The need of V-shaped constructions to be applied in gore areas at motorway exits. (3) A low price to make the attenuator widely applicable. The development led to RIMOB tested in experiments (IRRD 265958). Because RIMOB has been used for 7 years now an evaluation study could be made.
