• Abstract:
  Traffic congestion in the Washington, DC area, especially congestion on our freeways, costs our residents every day ; in terms of wasted time, fuel, and increased air pollution. Highway studies have determined that once traffic volumes ; exceed the capacity of the roadway, the system can rapidly “break down” to the point where all traffic slows ; markedly, and the capacity and throughput of the roadway drops precipitously. The Federal Highway Administration ; commissioned this study to specifically evaluate speed, volume and delay for congested versus uncongested travel on ; some of the major roadways in the metropolitan Washington region, in order to identify the specific “tipping ; point(s)” at which free-flow traffic “breaks down”, and conversely, the volume of traffic that would have to be ; reduced in peak periods to keep traffic free-flowing. The study also analyzed survey data to estimate the number and ; percent of trips that people take in peak hours on our freeways that are discretionary trips. Finally, the study briefly ; reviewed empirical findings on experiences with congestion pricing in the US and abroad.
