Crash data collected through the Wisconsin Motor Vehicle Accident Report Form and Badger TraCS (Traffic and Criminal Software) is the primary source for most types of transportation safety analysis. In 2017, the previous version of the form was replaced by a newer form (DT4000) that provides more relevant and complete information about crashes, including expanded fields related to pedestrian and bicycle crashes. This research project will address the questions such as what new insights and new values can the DT4000 enhancements offer to safety analysis, such as the prediction of pedestrian and bicycle injury severity? Hence, this project will accomplish two objectives: 1) conducting a thorough review and quantitative analysis of all DT4000 pedestrian and bicycle crashes reported since 2017; and 2) providing recommendations for direct improvement on the completeness and quality of pedestrian and bicycle crash data.
