EFFECTS OF WORK ZONE PRESENCE ON INJURY AND NON-INJURY CRASHES
Work zones in the United States have approximately 700 traffic related fatalities, 24,000 injury crashes, and 52,000 non-injury crashes every year. Because of future highway reconstruction needs, work zones are likely to increase in number, duration, and length. This study focuses on analyzing the effects of work zone duration mainly due to its policy sensitivity. A unique database was created of California freeway work zones that included crash data, road inventory data, and work zone related data. Then, crash rates and crash frequencies were investigated in the pre-work zone and during work zone periods. Next, crash frequencies were investigated using negative binomial models, which showed that frequencies increased with increasing work zone duration, length, and average daily traffic. The implications of the study findings are discussed in the paper.
