  • 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.
