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.
