Steps

  1. Open the 'Snow Plow Truck Location AVL' dataset (data.iowadot.gov/datasets/20a0c10c06a54240b5f2893e0187e22c_0) and use its /api page for the live ArcGIS Feature Service query endpoint.
  2. Query in GeoJSON or JSON — the layer only includes active Iowa DOT plow trucks currently traveling faster than 3 MPH.
  3. Poll on a 2-minute cadence to match the feed's update frequency (available 24/7 during winter operations).
  4. For broader 511 data (cameras, incidents, message signs) beyond plow AVL, separately request XML feed access via Iowa DOT's 511 data feeds page (iowadot.gov/travel-tools/iowa-511/511-data-feeds) and its integrator contact.
  5. Handle empty result sets gracefully — the dataset only shows trucks meeting the speed threshold, so no trucks returned during a storm lull is expected, not an error.
