• Abstract:
  This first-of-its-kind study examines a significant cause of traffic congestion - America's worst bottlenecks - from three perspectives. First, it examines how much worse the gridlock will become at each of the 18 worst bottlenecks in the United States if no improvements are made. Second, it makes individual, city-specific evaluations of the benefits of improving these locations. In particular, the report evaluates how fixing each bottleneck will: save lives - by reducing crashes and their attendant fatalities and injuries; save the environment - by reducing emissions of carbon dioxide (a greenhouse gas) and air pollutants; and save time - by reducing the delays (to motorists and buses) associated with congestions. Finally, the report calculates the combined benefits of improving bottlenecks nationwide. The U.S. overstressed road system needs additional capacity at key points. Providing that capacity by removing strategic bottlenecks, as part of an overall program of congestion relief, will reduce the amount of time commuters have to spend on the road, save hundreds of lives, prevent thousands of injuries, and help us safeguard the environment. 70p.
