Book Description
Information from driver studies performed during the first year of the project identified several features and conditions that created confusion and anxiety in traversing the work zone. Many of these conditions represented deficiencies in the work zone traffic control from the standpoint of positive guidance principles. This report describes the efforts to tailor the application of positive guidance procedures to work zone traffic control installations reviews. Four key steps, hazard visibility assessment, expectancy violation determination, information load analysis, and information needs specification, are described in the context of traffic control at potentially complex work zones. A methodology is presented for applying these steps in a field review process to be performed as part of the work zone traffic control installation process.

Book Description
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.
