Impact Attenuators provide safety during an impact with a roadside hazard. They protect concrete barriers, sign structures, bridge supports, gores and other hazards. Without these safety appurtenances, impacts with these hazards would cause severe injury or death so they are a very important piece of highway safety hardware. Maintenance costs of impact attenuators can be an extreme burden on transportation budgets. Many times, this translates into unmaintained impact attenuators or crash attenuators in various states of repair which is a very dangerous situation to the traveling public. Transportation agencies can reduce this burden and liability by using low maintenance attenuators in locations that meet criteria for when to use a low maintenance impact attenuator. The result is to find a balance between Safety and the Cost Effectiveness of these devices. This presentation shows the results of multiple studies on the use of low maintenance impact attenuators. It has the resulting cost of repairs for different impact attenuators. It presents the industry established criteria for when to use a low maintenance criterion. Additional safety benefits are laid out and defined. Summary of studies throughout USA and test locations here in British Columbia will be summarized. Present BC initiative where the Top Highest Incidence locations were evaluated and discussed. How maintenance contractors and MOTI / ICBC formed a partnership to develop this forward-thinking approach. Fiscal responsibility while maintaining our Transportation network.
* Applications
* Industry established Criteria to aid decision makers on site specific locations
* Increased responsiveness to impacted attenuators resulting in lower exposure to liability and increased safety
