Evaluation of Traffic Control Devices, Year 2

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 2010. There were five primary activities and five secondary activities. The five primary activities were: studying the impact of using high brightness retroreflective sign sheeting in rural areas, synthesizing the technologies available to potentially automate no-passing zone markings, providing hurricane evacuation support for the Corpus Christi District, monitoring lead-free thermoplastic pavement marking test decks, and demonstrating daytime and nighttime operations of traffic signs supplemented with light emitting diodes. In addition, the researchers also provided support for specification revisions, prototype traffic control device evaluations, technical support for Traffic Operations Division, and initiated a study on contrast pavement markings.
