• Abstract:
  This research study collected data from approximately 39,000 traffic collision reports including diagrams and narratives for years 2011 through 2017. These reports had to be tracked down, scanned, creating image files made of the diagrams and organizing the data into a searchable database. Furthermore, the narrative portions of each report needed to be converted to digital text and used to populate the data base. A web-based tool was also developed to illustrate how a user can use the collected data to query information and develop understanding of collision trends and attributes. A number of collision attributes are identified and combined with injury and collision cost models that can be used to assess societal cost of such collisions. The result is a data set and an analysis tool that can be used to assess attributes related to work zone collisions and can serve as a decision support tool for mitigation and improvement of highway safety.
