摘要: |
This project was established to provide a means of conducting small scale research activities on an as-needed basis so that the results could be available within months of starting the specific research. This report summarizes the research activities that were conducted between September 2009 and August 2013. Researchers evaluated bridge clearance signing and visibility; incorporating multiple-curve processing capabilities into the GPS method for setting advisory speeds; and guidelines for sign sheeting material for rural applications. |
