Abstract:To enable implementation of the American Association of State Highway Transportation (AASHTO) Highway Safety Manual using
SaftetyAnalyst (an AASHTOWare software product), the Arizona Department of Transportation (ADOT) studied the data assessment
and integration requirements. The research identified the data needs for the SafetyAnalyst software, assessed the quality of data
available, addressed all “required element” data gaps, and prepared the requirements for data input and post‐processing output
for presentation and interpretation. This research provides an overview of critical data needs and system requirements for ADOT’s
deployment of SafetyAnalyst, identifies gaps between existing and desired conditions needed for successful software
implementation, sets priorities for filling these data gaps, recommends a strategy for integrating the software into standard ADOT
practices, and recommends a technology strategy to support a phased implementation.
