Small sign systems include everything from stop signs and delineator posts to signs up to about 25 square feet. In some cases, multiple small sign support systems are used to support much larger signs (40-50 square feet). This broad class of sign has been and is currently being used along Texas highways. To insure the safety of vehicle occupants, there have been a series of specifications, guidelines and recommendations which define acceptable vehicle impact performance criteria. Most small sign systems have been tested with vehicles larger than the current standard 1800 pound car. As a result, the first phase of the study was to undertake a series of recertification tests for those systems currently being used in Texas. An analytical model also was developed to aid in the evaluation of data from previous crash tests. Although certification was achieved through crash testing, the analytical model proved to be an accurate predictor of impact performance with the smaller 1800 pound vehicle. The second phase of the study consisted of the development and testing of a generic small sign support system. The resulting generic ground anchor system can be used with any tubular sign post.
