Data Integration
The Michigan Experience

What's Next?

In 2002, the State of Michigan passed Act 499, which requires Michigan's transportation agencies to adopt Asset Management concepts and to meet these requirements:

• Report to the legislature the condition and service levels of all Federal-aid-eligible roads and bridges
• Report the 3-year road and bridge program of projects for all State, county, and city agencies
• Develop performance-based investment strategies for condition and service targets

Meeting these guidelines will require the integrated database and single basemap activities initiated at MDOT to be maintained and extended to allow city and county providers to use them.

Additional data integration issues that MDOT will be focusing on as it continues to implement Asset Management concepts include:

• Definition of data elements and collection techniques necessary to determine the life cycle cost of various capital and maintenance treatments
• Integration between financial databases and Asset Management systems to fully analyze the relationship between fiscal constraints and condition targets
• Integration of ITS activities and real-time data collection capabilities in the planning and programming process

MDOT is also in the process of implementing Web-based front ends to selected applications. For example, the Public Transportation Management System and the bridge inspection component of the Pontis bridge management system are currently being migrated to the Web.
