• Abstract:
  Electronic crash reports are advantageous because they can limit missing data, transcription errors, and the space ; limitations of a single sheet of paper. Advancing electronic reports through user-centered design affords an ; opportunity to improve law enforcement officer’s (LEOs) ability to accurately, timely, and efficiently document ; crashes. Minnesota’s commencement of a new crash records database offered a unique opportunity for a redesign ; of its electronic crash report to best support LEOs. A well-designed electronic report will not only support LEOs in ; the line of duty but will also lead to more useful, complete, and accurate data for various state and federal agencies ; for analysis and policy decision making. The objectives of this project were to: 1) improve crash data reliability an ; validity, 2) develop a framework crash report interface based on human factors principles and usability ; requirements, and 3) reduce the mental workload and required steps for users. Project tasks included: heuristic and ; hierarchical task analysis, cognitive walkthroughs, validity and reliability testing, interviews, beta testing, and ; usability testing. The human factors principles and user-centric approach lead the iterative design process to ; produce a product with high levels of usability and intuitiveness. The project featured a cooperative approach ; among university researchers, state agencies, and a private developer to ensure that the knowledge, design, and ; results of the research effort was fully transferred into the final product. The resulting interfaces preliminarily ; suggest improved user satisfaction, along with data completeness and accuracy, and provide a resource for ; replication in multiple domains.
