1. Office of the Federal Coordinator for Meteorology OFCM Surface Transportation Weather- Related Impact/Priority Data Paul Pisano Mike Campbell WG/WIST Cochairs June 6, 7, 13, and 14, 2006 WIST R&D Prioritization

2. Office of the Federal Coordinator for Meteorology OFCM Overview Background Weather-related impact data by sector –Road –Rail –Marine –Transit –Pipeline –Airport Ground Operations Intended Use Next Steps

3. Office of the Federal Coordinator for Meteorology OFCM Background Selected four criteria that matched the WG/WIST goals: –Fatalities –Injuries –Delays –Costs WG/WIST then requested weather-related impact data from all surface transportation sectors –Looking for weather events/parameters having the greatest impacts –Could the data be aggregated into an overall weather-related impact data table? How should WG/WIST prioritize R&D needs?

4. Office of the Federal Coordinator for Meteorology OFCM Background Roadway—state and federal highways, roads, and streets Long-Haul Railway—rail lines providing intercity freight and passenger service, with their yards, stations, and depots Marine Transportation System (MTS)—coastal and inland waterways, ports and harbors, and the intermodal terminals serving them Rural and Urban Transit—bus and van service on streets and roadways, rail lines for metropolitan subway and surface “light rail” systems Pipeline Systems—Above and below ground pipelines for commodities such as crude oil, refined petroleum products, and natural gas, plus the storage, transfer, and pumping facilities for pipelines Airport Ground Operations—All ground movement of vehicles, work crews, and passengers WIST Report defined six surface transportation sectors

11. Office of the Federal Coordinator for Meteorology OFCM Intended Use Help define the weather events/parameters having the greatest impact on the surface transportation system’s safety and operations –Look for common themes across sectors, but do not lose unique impacts within a sector Use as a first-cut method to guide prioritization of WIST R&D needs –May need to refine/augment to include non-weather items (e.g., data management, information dissemination)

12. Office of the Federal Coordinator for Meteorology OFCM Next steps Finish data collection Complete the definition of cost versus delay –Checking that the data used to rank weather events/parameters is common across sectors Decide whether to aggregate data across sectors to define an overall ranking for each weather event/parameter or leave separate for each sector –Initial thought is that we need to retain sector-unique impact rankings to allow for a more refined analysis within sectors
