Portable sign post structures currently in use by the Pennsylvania Department of Transportation, supporting signs less than less than 36 inches square at heights of 7 feet off the ground, are assembled using varying techniques and materials and do not meet crash testing standards established in NCHRP 350. This project was performed to review available crash-tested portable sign post structures and, based on this review, design and crash test a new model to meet the NCHRP 350 criteria and establish a standard PennDOT support design protocol. The objectives of the project were to: (1) search available literature to establish the state of the art for portable sign post structures in the United States for further study; (2) perform numerical modeling of selected sign posts' designs to present optimal designs for crash testing according to NCHRP 350; (3) develop a crash testing plan for sign posts recommended by PennDOT and have the plan approved by relevant PennDOT Personnel; and (4) perform crash tests of selected sign post designs, report on the findings of the crash tests and develop standard drawings.
