Summary from: Roadway Safety Data Program | Arizona Importing Local and Tribal Data for Safety Analysis | FHWA-SA-16-061

Background

The Arizona Department of Transportation (ADOT) and the Federal Highway Administration (FHWA) Office of Safety completed a pilot project that allows the State to acquire roadway data elements from local and Tribal agencies and load the data into the Arizona Transportation Information System (ATIS) database. ADOT created a new process that allowed business users to import the data from local agencies, export combined State and local/tribal data, and load data into AASHTOWare Safety Analyst™ for analysis. ADOT used contractor support to establish data integration procedures for crash, roadway, and traffic volume data for both roadway segments and intersections. The results from the pilot created processes for the data submissions to ADOT, data integration in ATIS, the process for bringing data into AASHTOWare Safety Analyst™, and quality control checks prior to analysis.
