Create a statewide intersection safety and roadway elements database. (Incorporate the MIRE format; create a standardized data structure to support GIS applications; create an app for data collection; develop partnerships between TxDOT, MPOs, and local agencies to populate the database; and develop and implement an intersection identifier system for posting at intersections.)
- Develop ramp data and edit GIS line work to ensure the roadway network is topologically correct.
- Conduct a Geospatial Roadway Inventory Database (GRID) software enhancement project to incorporate an intersection/interchange inventory.
- Develop algorithms to generate intersections and derive descriptors and location identifiers such that all MIRE fundamental data elements are fully incorporated into the roadway inventory system.
- Maintain the database.
