Transportation Asset Management Case Studies
Data Integration: The Virginia Experience

Executive Summary

Virginia has the third-largest State-maintained highway system in the country. State legislation requires the Virginia Department of Transportation (VDOT) to fund the maintenance of this system before funding capital improvements. To ensure the best possible maintenance investment decisions, VDOT initiated a comprehensive maintenance and operations business process reengineering (BPR) effort in 1995. This effort laid the groundwork for what is now widely known as Transportation Asset Management.

Based on recommendations from the BPR effort, VDOT initiated the development of infrastructure decision-support systems and a large data collection program, referred to as the Inventory and Condition Assessment System (ICAS).

In 2002, the Virginia General Assembly passed legislation that requires VDOT to incorporate the principles of asset management into its maintenance and operations practices and to submit biennial reports that document performance targets and compare actual conditions to those targets. This legislation was one of the main drivers for VDOT to modernize its effort to develop an integrated asset management system.

VDOT's new data integration strategy has enabled it to make significant progress in the development of decision-support tools and the integration of asset management data without waiting for the details of the final Asset Management System. This system may evolve, for example, into a suite of individual tools or into a large, enterprise resource management system. If all relevant data are cleansed, normalized, and stored in a single data repository, VDOT will be able to export data to any future system.

In 2003, VDOT completed the Needs-Based Budget Request Module of the Asset Management System. This module enables VDOT staff to develop maintenance budgets that reflect the current condition of its assets. The module has already made an impact through its ability to provide information to decisionmakers on VDOT's executive board. Based on these initial success stories, VDOT is moving forward with additional components of what will eventually be a fully integrated infrastructure Asset Management System. VDOT expects to realize a 15 percent return on its investments in the system by 2006.
