Study: Atlanta Could Get $15 Billion Boost by Reducing Traffic Congestion

Prioritizing infrastructure that reduces traffic jams can spur big economic gains

With the economy stuck in a recession and Atlanta facing a major budget deficit, a new Reason Foundation report finds that reducing traffic congestion and improving travel times could create jobs and boost the region's economic output by as much as $15 billion a year.

The Reason Foundation report examines the impact that population growth and longer commute times will have on five areas across Atlanta by 2030: downtown, Emory University, Cumberland Mall, Panthersville, and Hartsfield-Jackson International Airport.

Of those locations, the Reason study says the biggest economic gains would come from eliminating severe congestion around major suburbs such as Panthersville, which could add $15 billion a year to the regional economy and up to $1 billion in additional annual tax revenues. The report found similarly large economic benefits for suburbs in Charlotte, Dallas, Denver and Seattle.

Improving accessibility around major retail sites such as Cumberland Mall and around colleges like Emory University could produce over $12 billion in annual economic benefits. Reducing traffic around downtown Atlanta and Hartsfield-Jackson Airport could deliver over $5 billion per year in economic gains the study finds.

"This report shows how important it is to prioritize taxpayer money on infrastructure projects with the best benefit-cost ratios," said Adrian Moore, vice president of research at Reason Foundation. "If you focus on the projects proven to improve mobility and eliminate traffic jams, your investment will be rewarded several times over. Shorter travel times increase worker productivity, spawn more jobs and help create more shopping, entertainment and dining choices."

"We studied eight cities and the findings are clear," said David Hartgen, author of the report, senior fellow at Reason Foundation and emeritus professor of transportation at the University of North Carolina at Charlotte. "Reducing traffic congestion by 10 percent improves productivity by over one percent. One percent may sound small, but in a city like Atlanta, it can mean tens of billions of dollars in economic gains. The biggest gains come from enhancing mobility around suburbs, universities and malls. Smaller economic increases are made around central business districts and airports."

Traffic congestion is going to have increasingly negative impacts on Atlanta's economy in the coming decades. The Reason Foundation says that by 2030 traffic congestion in Atlanta will be worse than it is in today's gridlock capitol of America, Los Angeles. Reason finds that if infrastructure investments are aimed at the projects that will relieve the most traffic, Atlanta needs to spend approximately $15 billion (in 2005 dollars) to eliminate severe traffic congestion by 2030. That's actually just a fraction of the more than $53 billion that the region plans on spending on transportation in its current long-range plans.

The study makes several recommendations, including:

  • Pay more attention to the accessibility of various locations, not just downtown.
  • Remove bottlenecks throughout the region. Relatively modest expenditures can have major impact on travel times, particularly if congestion is relatively concentrated geographically.
  • Add road capacity in and around the rims of cities. Investment in suburban accessibility often offers a very good return rate.

The Reason Foundation study takes an in-depth look at traffic and economic growth in Atlanta, Charlotte, Dallas, Denver, Detroit, Salt Lake City, San Francisco and Seattle.
