The study involves the development of an accident data reporting process for use in construction, maintenance, or utility work areas. The process is based on the results of a 9 state survey which collected information on practices and procedures which were in use in those states.

Work zone crashes and fatalities have been decreasing since 1994. Yet, according to Fatality Analysis Reporting System, 667 people were killed in highway work zone crashes in 2009. As the United States' infrastructure ages and new roads and highways are constructed less frequently, the need for repairs and alterations to the nation's roadways is continually increasing. This growth ensures that work zones will be a vital piece of design focus in the near future. In order to continue the decreasing trend in work zone crashes, and reduce the still significant number of work zone fatalities, work zones need to continually be examined to identify opportunities for improved safety. This research explored the relationship between work zone related crashes and work zone design and setup. More specifically, existing literature and current standards, compiled with crash report form data in the UMass Safety Data Warehouse and field observations in Massachusetts were integrated to determine the causes and remedies for work zone related crashes. The research examined three critical areas: 1) causation of work zone related crashes in contrast to non-work zone related crashes along with variations of citations as a result of work zone crashes; 2) variations of the work zone definition and the impact on work zone involvement; and 3) analysis of conflict and event studies for small scale work zones to develop a methodology using surrogate measures to identify potential countermeasures leading to improved work zone safety. The results are expected to advance the current state of knowledge with regards to work zone design and setup, resulting in recommended actions for improved work zone analysis and design strategies.

This report presents the results of a study of reported crashes that occurred in selected work zones from four participating States: California, Maryland, Minnesota, and Washington. Candidate construction projects were identified by the State Transportation Agencies. Data on the location of the project, the start and end dates, the type of project, the type of highway, and other factors were compiled for each project. In addition, data on the work zone was also gathered. Crashes reported when the work zone was in effect and for the corresponding period before the construction project were identified and crash data were obtained. Analyses were undertaken to determine differences in crash rates during construction compared to before construction. The relative increase in rates was on the order of 25 to 50 percent for many of the projects and as much as 100 percent for some of the projects. In addition, an assessment of data elements for work zones and work zone crashes was conducted. Recommendations on a standardized definition for work zones and work zone crashes are proposed.

The report includes results of two studies of construction zone traffic control. The first study involved analysis of traffic accidents occurring in 79 zones in seven states. Results indicate a before to during accident rate increase of 6.8%. Results also include breakdowns by accident types, severity, light conditions, roadway type, area type, work area roadway type, construction type and state. The second study was field testing of speed reduction methods. Speeds, erratic maneuvers and conflicts were measured at three sites--an urban freeway, a rural freeway, and an urban street. The field studies examined the effect of the following construction zone parameters on vehicle speeds and safety: Sequential flashing arrow boards; speed zoning (advisory and regulatory); enforcement; transverse striping; obliteration of nonappropriate pavement markings; taper length; lane width reduction; and active warning of speed zoning. Recommended guidelines for construction zone traffic controls are also included.

The work zone accident data process is a data collection and processing procedure which starts at the construction and maintenance work site and transmits information through the regular communications channels to the state highway agency headquarters. The process is a supplement to regular police accident reporting and is used to provide a supplement to regular police accident reporting as well as long range summaries (statewide application).
