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 where the roadway was not under physical repair (e.g., sweeping and landscaping) or where the first event in the accident was not related to the work activity (e.g., driver falling asleep). 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
