Abstract:This project was established to provide a means of conducting limited scope evaluations of numerous traffic ; control device issues. During the fifth, and final, year of the project, researchers conducted four activities: ; improving the interface for the automated process for identifying the start and end of no-passing zones ; developed during the fourth year, continuing the evaluation of the performance of lead-free yellow ; thermoplastic pavement markings started at the end of the fourth year, continuing development of the Work ; Zone Implementation Handbook, and creating an updated edition of the Sign Crew Field Book. The last two ; of these activities produced stand-alone documents for Texas Department of Transportation (TxDOT) use. ; The evaluation of lead-free thermoplastic found that the material performs well in most, but not all, areas. ; The improved interface for the automated no-passing zone was tested in the field at two sites, and the results ; indicate that the results are consistent with existing no-passing zone markings when considered for vertical ; alignment only.
