ET-Plus Guardrail
The ET-Plus Guardrail system is a guardrail end terminal system manufactured by Trinity Industries, Trinity Highway Products, based in Dallas, Texas. The ET-Plus was designed at the Texas A&M Transportation Institute and built by Trinity. The end terminal cap absorbs the impact of a crash. The wooden posts break and the guardrail collapses. The end terminal slides along, pushing the guardrail to the side. However, in 2005, Trinity made changes to the ET-Plus without reporting the changes. It was alleged that the Trinity design change caused it to malfunction. A lawsuit under the False Claims Act filed in 2012 against Trinity stated that these changes were causing damages to cars and drivers. Tests have shown that the guardrails act the way they should. History In the 1980s, Texas A&M Transportation Institute (TTI) had been conducting researches to improve guardrail safety for head-on collisions of guardrail ends. As a result, it developed the first model of energy-absorbing guardra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guardrail End Terminal
Traffic barriers (known in North America as guardrails or guard rails, in Britain as crash barriers, and in auto racing as Armco barriersAK Steel (formerly Armco) genericized trademark) keep vehicles within their roadway and prevent them from colliding with dangerous obstacles such as boulders, sign supports, trees, bridge abutments, buildings, walls, and large storm drains, or from traversing steep (non-recoverable) slopes or entering deep water. They are also installed within road median, medians of divided highways to prevent errant vehicles from entering the opposing carriageway of traffic and help to reduce head-on collisions. Some of these barriers, designed to be struck from either side, are called median barriers. Traffic barriers can also be used to protect vulnerable areas like school yards, pedestrian zones, and fuel tanks from errant vehicles. In pedestrian zones, like school yards, they also prevent children or other pedestrians from running onto the road. While barr ...
