Literature Review 11 Through data mining, information that already exists in state-maintained roadway inventories and stand-alone information systems maintained for road infrastructure can be accessed. While this method removes the need to manually collect new databases, the currently existing data may not have the necessary information, and not all roadways may be covered.

14 Integration of Roadway Safety Data from State and Local Sources compare or share crash data between states, between state and federal data sets, and, in some cases, even between different agencies within a state. To assist states in evaluating their consistency with the MMUCC, NHTSA and the Governors Highway Safety Association developed a methodology for mapping the data collected on crash reports and the data entered and maintained on crash databases to the data elements and attributes in the MMUCC Guideline.
