Seeking to identify how Arizona Department of Transportation could accomplish the greatest service improvements with the most efficient use of funds, ADOT engaged ARCADIS to perform a Crash Data Collection and Analysis study and examine the possibilities offered by technological innovations such as Electronic Data Entry, Relational Database Management Systems, and Geographic Information Systems. The study resulted in a comprehensive report with three components: an examination of best practices in use in the United States today, a use case and gap analysis examining ADOT's current data work, and a technical memorandum outlining how changes could be implemented.
