PAS 2161 specific requirements for road network geometries in RoadAI

You may need to update the road network geometry you use in RoadAI to ensure it is compatible with PAS 2161 reporting. As a minimum criteria, the road network geometry must define the following for each segment:

  1. A unique identifier

  2. Road name, if present (for example, “Station Road”) and classified road number, if present (for example, “A3”)

  3. Geographic location (grid coordinates) of the start point

  4. Geographic location (grid coordinates) of the end point

  5. Segment length in meters (to two decimal places if available)

  6. Classification (for example, M, A, B, C, or U)

  7. Type (for example, dual, single one way, single two way, or roundabout)

  8. Function (for example, main carriageway, slip road, or roundabout)

  9. The number of permanent lanes in the segment (for example, 1, 2, or 3)
