This case study documents how the Missouri Department of Transportation’s (MoDOT’s) Transportation Planning Division (TPD) coordinates with the Information Systems unit (the agency’s information technology unit) and the State’s Traffic Records Coordinating Committee (TRCC) to form a leadership group that supports the State’s data management and integration activities. The State’s Transportation Management System (TMS) stores all transportation-related data maintained by the agency. This Oracle-based database, directly managed by TPD, ties all asset data to a single, all public roads base map and linear referencing system (LRS). This provides a tabular LRS location and a spatial location compatible with geographic information systems (GIS) software for all data elements located along Missouri’s public roads network. This spatial orientation supports several data management and integration efforts between different business units within MoDOT, as well as with external partners that manage relevant safety data. The DOT committed to spatial data integration early in the development of the TMS, and it has led to the flexible and expandable repository that exists today.
