Abstract:Demand for highway travel by Americans continues to grow as population increases, particularly in metropolitan areas. New highway construction that accommodates this growth in travel has not kept pace. Between 1982 and 2002, highway lane miles increased 3.0 percent while vehicle miles of travel increased 79 percent. The Texas Transportation Institute estimates that in 2001, the 75 largest metropolitan areas together experienced 3.5 billion vehicle-hours of delay, resulting in 5.7 billion gallons in wasted fuel and $69.5 billion in lost productivity. And traffic volumes are projected to continue to grow. The volume of freight movement alone is forecast to .nearly double by 2020. Congestion is largely thought of as a big city problem, but delays are becoming increasingly common in small cities and some rural areas as well.
