This annual report includes 20 years (1982-2001) of data on mobility and traffic congestion for 75 urban areas in the United States. Statistics from generally available data sources are used to provide information about mobility trends at the urban area level of detail. In addition to presenting statistics, the report reviews what happened to those areas during the 20 years studied: traffic congestion grew in areas of every size, roads and public transportation systems handled more trips, and traffic congestion costs increased. The study includes an estimate of the effects of several common solutions to congestion problems, including additional road lanes and demand management and demand reduction programs. Freeway entrance ramp metering, freeway incident management, traffic signal coordination, public transportation service and high-occupancy vehicle lanes are also addressed.
