The objective of this study was to determine the magnitude and characteristics of safety problems, in terms of reported accidents, that are associated with moving vehicular traffic around and through highway maintenance and utility work zones. This was accomplished by examining 280 maintenance and utility work zone accidents that occurred on the Virginia state highway network over a period of 14 months. These represented approximately 0.4% of the total number of accidents reported during that period. A review of accident reporting procedures, however, indicated that the sample of accidents examined did not include a variety of work zone accidents. The report discusses several characteristics of the maintenance and utility work zone accidents including general and specific locations of the accident, time of the accident, roadway and environmental factors, characteristics of the work zone, cause of the accident, and accident severity. Where data were available comparisons were made between the maintenance and utility work zone accidents and all reported accidents.
