The report provides a snapshot of congestion in the United States by summarizing recent trends in congestion, highlighting the role of unreliable travel times in the effects of congestion, and describing efforts to curb congestion. In particular, the report develops a framework for understanding the various sources of congestion, the ways to address congestion by targeting these sources, and performance measures for monitoring trends in congestion. Much of the report is devoted to measuring recent trends in congestion. One of the key principles that the Federal Highway Administration (FHWA) has promoted is that the metrics used to track congestion should be based on the travel time experienced by users of the highway system. The different aspects of congestion are discussed using a variety of data sources, with perhaps the newest aspect being the role of reliability in the congestion problem.
