Work Zone Injury Data Collection and Analysis

Work-zone related injuries and fatalities are a major safety concern in California and nationwide. Developing mitigation measures is vital in improving work zone safety both for roadway workers as well as the traveling public. Developing such measures, however, require detailed data on the characteristics of these accidents and injuries produced in them as well as injury costs models that can be used for cost benefit assessments. Although there exist databases and data sources such as the Statewide Integrated Traffic Records Systems (SWITRS), NHTSA's (National Highway Traffic Safety Administration’s) FARS (Fatality Analysis Repotting System) database, and Caltrans TASAS (Traffic Accident Surveillance and Analysis System), none can provide the information that would justify particular mitigation measures, or allow cost benefit analysis. This research was conducted to develop such data, codify and classify it in terms of factors and outcomes and provide analysis tools in terms of injury costs. It involved collecting, codifying and classifying all Traffic Collison Reports for accidents occurring near a work-zone from 12 Caltrans districts for a period of five years (2006-2010). Extracted data from these reports were codified in terms of factors and outcomes and made part of a decision support system designed to allow analysis of the data that can be used for planning and management of work-zone operations to improve worker and motorist safety
