Countermeasure: Intersection database
Intersection Database Action Plan
Description

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.)

Steps For Implementation
  1. Develop ramp data and edit GIS line work to ensure the roadway network is topologically correct.
  2. Conduct a Geospatial Roadway Inventory Database (GRID) software enhancement project to incorporate an intersection/interchange inventory.
  3. 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.
  4. Maintain the database.
