| 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 small-scale research activities that were conducted between September 2008 and August 2009. There were four primary activities and two secondary activities. The four primary activities were: developing a temporary sign support with cross bracing, providing technical support on an AASHTO retroreflective sign sheeting material specification, conducting human factors research on sign sheeting materials, and monitoring lead-free pavement marking test deck performance. In addition, the researchers also provided support for hurricane evacuation routing and started a research activity focused on identifying traffic signs with supplemental light emitting diodes (LEDs). |
