Rethinking the Economics of Traffic Congestion

With a few notable exceptions, transportation planning practice in the United States is focused on managing or eliminating traffic congestion. Regardless of whether planners are advocating for highway infrastructure to improve level-of-service, or transit projects intended to “get cars off the road,” the underlying assumption is that congestion relief is an unmitigated good.

Such arguments are often based on the idea that traffic congestion and vehicle delay are bad for the economy. According to the Texas Transportation Institute, vehicle delay costs Americans $115 billion in wasted fuel and time each year. The common interpretation of such statistics is that our cities and regions would be so much more economically productive if only we could eliminate the congestion that occurs on urban streets.
