Abstract:

This case study highlights a noteworthy example by the Arizona Department of Transportation (ADOT) as the State focuses on the quality of its linear referencing system (LRS). ADOT uses the LRS as the system of record to help manage and integrate datasets between several units and data owners in the agency. ADOT developed a framework for identifying critical issues with its LRS, such as gaps and overlaps in feature records. This process allows ADOT to trace systemic issues and correct them programmatically. This case study also explores how ADOT is advancing the State’s LRS to improve safety data integration and support advanced use cases in data management and analysis. Communication with the State’s traffic safety team and information technology staff has been critical to collecting and maintaining essential safety data on State highways and local roads. This has helped ADOT build institutional knowledge with respect to key concepts and pursue more advanced safety data applications.
