SMART SIGN SUPPORT

The Route 80-MAGIC (Metropolitan Area Guidance, Information and Control) project is considered to be the showcase Intelligent Transportation System (ITS) project for the state of New Jersey. The project consists of a total of 72 miles (116 km) of intelligent highway starting at the George Washington Bridge near New York City and continuing westerly, and including parts of the New Jersey Turnpike and some of the most congested traffic areas within the state. There are 35 variable message signs, used to post traffic information for drivers, located in advance of interchanges and along selected diversion routes throughout this project. Supporting these large structures safely over the roadway presents special challenges not covered by existing design specifications. The New Jersey Department of Transportation engaged Lehigh University to instrument a cantilever sign structure and to help develop a design criteria that would address the fatigue design from loads imposed by truck and natural wind, including wind buffeting.
