Testing Develops Crashworthy Sign SupportsAuthor/Presenter: Bligh, Roger P.
Recent research conducted under a cooperative program between the Texas Transportation Institute (TTI), the Texas Department of Transportation (TxDOT), and the US Department of Transportation, Federal Highway Administration (FHWA) has resulted in the development of a crashworthy temporary sign support that reduces the probability of injury when these devices are impacted. The failures that were encountered during the development process clearly illustrate the importance of following the recommended design details when building. However, when properly fabricated and deployed, this temporary sign support can contribute to a safer work zone for both motorists and construction workers.
