Abstract:The Texas Department of Transportation (TxDOT) is responsible for managing 1.1 million acres of land that
provide right of way for approximately 80,000 centerline miles of state-maintained roads. Management of
the huge right of way asset involves considerable resources and the integration of numerous business
processes. There is an urgent need to develop a right of way asset data architecture to facilitate the inventory
and management of TxDOT right of way assets. This architecture would facilitate the identification of
current right of way boundaries, tracking of right of way boundary changes, automatic mapping of right of
way surveying data to other layers of information such as control section job and route number locations, and
complete attribution of right of way assets. It would also simplify the production of reports, including those
needed to address financial reporting requirements.
As part of the research, the researchers evaluated current right of way data practices at TxDOT and other
agencies, and developed and tested a prototype geographic information system (GIS)-based right of way
asset data model. The data model included a logical model, a physical model, and data dictionary, following
current TxDOT data architecture standards and findings from recent research and implementation projects.
