Trends in Urban Roadway Congestion: 1982 to 1991. Volume 2. Methodology andUrbanized Area Data

摘要

The research report represents the sixth year of a ten-year research effortfocused on quantifying urban mobility. The study contains the facility information for 50 urban areas throughout the country. The database used for this research contains information on vehicle travel, system length, and urban area characteristics from 1982 to 1991. Various federal, state, and local agencies provided the information used to update and verify the primary database. An analysis of the cost of congestion was also performed using travel delay and increased fuel consumption as estimated quantities. The impact of congestion was also estimated by the amount of additional facility capacity required to provide urban mobility. Congestion costs were estimated on an areawide, per registered vehicle, and per capita basis.
