Highway departments, which are responsible for maintenance of different highway facilities, have the continuing responsibility to make the highway as safe and efficient as possible. Traffic control approaching and within a work-zone is a major concern for these departments. The objective of this study was to test three traffic control devices white lane drop arrows, orange rumble strips, and the CB wizard alert system for their effectiveness in improving merging, and reducing speed and speed variance at an interstate highway work-zone in Missouri. Statistical tests were conducted on the speed related data collected along the approach to the work-zone lane closure when the devices were not in place and when they were in place. Results of implementing the white lane drop arrows and the CB wizard alert system indicate decreases in the percentage of vehicles in the closed lane, mean speed and speed variance. It also appears that the CB wizard alert system may be more effective than the white lane drop arrows. The CB wizard alert system in conjunction with the orange rumble strips did show similar reductions, but they were much smaller in comparison to the CB wizard alert system alone.

This study was conducted to determine the truck drivers' travel characteristics, concerns about work zone traffic control devices, and assessment of work zone features, as well as to determine the location of accidents and bad driving situations based on the experiences and perceptions of truck drivers. A statewide survey of semi-truck drivers was conducted in 6 locations in Illinois. The questionnaire contained 43 questions about truck drivers and travel characteristics, drivers' assessment of work zone features and traffic control devices, their accident and bad driving situation experiences, and their suggestions for improving traffic flow and safety in the work zones. About 930 truck drivers participated in the survey, and the responses from 834 of them were found suitable for further data analysis. The frequency of the responses to each question were analyzed. Also correlation analyses were conducted to identify the relationships among the surveyed questions. Different statistical tests were used for data analysis. Volume II of the final report, contains a detailed report of the study, including all of the information that is included in Volume I, which contains the summary of findings, conclusions, and recommendations.

"TRB's National Cooperative Highway Research Program (NCHRP) Report 746: Traffic Enforcement Strategies for Work Zones presents guidance for the safe and effective deployment of traffic enforcement strategies in work zones on high-speed highways (those with speed limits of 45 mph or greater). The report discusses the planning, design, and operation of traffic enforcement strategies, as well as administrative issues that should be considered. The contractor's final report providing background information for the project that produced NCHRP Report 746 was published as NCHRP Web-Only Document 194: Traffic Law Enforcement in Work Zones: Phase II Research.

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.
