Extension Candidates 4 https://www.transportation.gov/av/data/wzdx

Extension Candidate Focus This Iteration #270: Add Incident Event Type #276: Add Disasters Enumeration #277: Add Special Events Enumeration #285: Add Winds Enumeration #299: Add Accident and Incident Enumerations #300: Add Polygon Geometry Type #269: Add event_cause to Restriction Event #264: Add Vehicle Impact to Restriction Event Candidate Features Seasonal Use Road Pavement Condition Draw Bridge Reversable Lane School Zone School Crossings Appropriate Vehicle (4WD, Non-Motorized) Evacuation Routes HazMat Routes

#270 Add Incident EventType Similar to Work Zone Data Events 3 Exceptions: Drops types_of_work, Optional end_date, Adds incident_type How Different than WorkZone or Restriction Events No Road Work Being Performed Restrictions are persistent Locates and describes crashes, incidents, or events How Different than TMDD? GeoJSON is readily consumed by mapping software WZDx s IncidentRoadEvent are more accessible Ability to indicate workers present 6 https://www.transportation.gov/av/data/wzdx

Add new Road Incident Feed Type Debate: Should we publish more than one Event Type in a Road Event Feed. E.g. Including Work Zones and Detours in the same GeoJSON Consensus: No, Don t Comingle Event Types Because were not comingling event types Need a new RoadIncidentFeed Type to serve IncidentRoadEvents 7 https://www.transportation.gov/av/data/wzdx

Add incident_type Enumerations The incident_type property is populated using enumerations from the TMDD #299: Accidents and Incidents #276: Disasters Enumeration #277: Special Events Enumeration #285: Winds Enumeration 8 https://www.transportation.gov/av/data/wzdx

Issue #299: Add Accidents & Incidents Enumeration accident serious accident injury accident minor accident multi vehicle accident numerous accidents accident involving a bicycle accident involving a bus accident involving a motorcycle accident involving a pedestrian accident involving a train accident involving a truck accident involving a semi trailer accident involving hazardous materials earlier accident medical emergency secondary accident rescue and recovery work REMOVED accident investigation work incident stalled vehicle abandoned vehicle disabled vehicle disabled truck disabled semi trailer disabled bus disabled train vehicle spun out vehicle on fire vehicle in water vehicles slowing to look at accident jackknifed semi trailer jackknifed trailer home jackknifed trailer spillage occurring from moving vehicle acid spill chemical spill fuel spill hazardous materials spill oil spill spilled load toxic spill overturned vehicle overturned truck overturned semi trailer overturned bus derailed train stuck vehicle truck stuck under bridge bus stuck under bridge accident cleared incident cleared 9 https://www.transportation.gov/av/data/wzdx

Issue #276: Add Disasters Enumeration flash flood major flood reservoir failure levee failure tsunami tidal wave volcanic eruption ash fall lava flow serious fire forest fire wildfire building fire brush fire grass fire fire danger extreme fire danger very high fire danger high fire danger medium fire danger low earthquake damage air crash rail crash toxic release toxic leak radioactive release radiation hazard reactor leakage explosion major hazardous materials fire 10 https://www.transportation.gov/av/data/wzdx

Issue # 277: Add Special Events Enumeration major event Airshow hot air ballooning concert state occasion VIP visit show festival exhibition performing arts outdoor market fair carnival fireworks display trade expo movie filming presidential visit parade procession funeral procession crowd holiday traffic crowds event ended 11 https://www.transportation.gov/av/data/wzdx

Issue #285: Add Winds Enumeration tornado hurricane hurricane force winds tropical storm gale force winds storm force winds strong winds moderate winds light winds calm gusty winds crosswinds windy strong winds have eased strong wind forecast withdrawn 12 https://www.transportation.gov/av/data/wzdx

Issue #300: Allow Polygon Geometry Type Data consumers can use polygons to mark roads within an area as closed or restricted due to events or incidents. Removes the administrative burden No need to mark individual roads as closed or restricted Consumer Uses Publisher s Polygon to Indicate Road Status E.g. All roads within this polygon are closed. Use Case: Art Festivals, City Marathons, 4th of July 13 https://www.transportation.gov/av/data/wzdx
