Michigan DOT's investment in the development of their Transportation Management System has helped to change the way the agency is organized, and how they approach data integration - a key element of their decision-making process. This case study details the data integration process at Michigan DOT, and how it has been developed as a critical part of MDOT's asset management framework. The report is part of the FHWA Office of Asset Management's series of case studies on TAM, produced with the goal of sharing information between agencies to improve efficiency.
