Title:
Estimating Adverse Weather Impacts on Major U.S. Highway Network
Abstract:
This paper presented a framework for estimating the impact, in terms of delay, of adverse weather events on travel in the United States. The Speed estimation methodology for travel in adverse weather was based on the Highway Capacity Manual. Using GIS and database tools, one can estimate travel delay and other relevant statistics at various resolutions including weather forecast zone, county, FHWA urbanized area, metropolitan area, state, and national levels. The estimation procedure employed NCDC's Storm Data and FHWA's HPMS and NHPN databases, which are all publicly accessible. The estimation procedure, which can be implemented repeatedly to assess the change from one year to the next, was used to estimate adverse weather impacts for the year of 1999.
