摘要：	Traffic congestion in the U.S. is bad and getting worse, and it is expensive. Appropriate solutions to this problem require appropriate information. A comprehensive and accurate analysis of congestion costs is a critical tool for planning and implementing policies to improve traffic conditions not only because the information will aid decision making and provide a basis for evaluating the effects of public interventions, but also because it will sensitize public opinion about the importance of solving congestion problems. According to the Texas Transportation Institute.s (TTI) Urban Mobility Report, which produces the most widely used estimates of the cost of congestion, in 2005, the average peak-period traveler in the urbanized areas of the country experienced an additional 38 hours in travel times and consumed an additional 26 gallons of fuel due to congestion. That means an aggregate of 4.2 billion hours of travel delay and 2.9 billion gallons of wasted fuel, representing a monetary cost of $78.2 billion, up from a cost of $14.9 billion in 1982. In Florida six of the seven urban areas with individual estimates in the Urban Mobility Report are classified as having much higher congestion or higher congestion when compared with similar regions across the country. The cost of congestion in these seven urban areas is $5.2 billion. These estimates, however, are intended for comparisons of trends for individual cities and, by definition, they are aggregate and general. TTI itself acknowledges these limitations stating that local and state studies are typically more detailed and relevant. For this reason, in this research, we conducted a more detailed study of congestion costs with the objective of filling some of the gaps of the Urban Mobility Report: (1) TTI just shows individual estimates of seven urban areas in Florida; (2) TTI does not take into account rural areas; (3) TTI does not allow a spatial understanding of congestion; (4) TTI uses national averages of constants and general estimations instead of specific state or local information; and (5) TTI omits important costs of congestion.
