Traffic problems have stagnated along with the economy, but an annual study just published suggests that too little progress is being made toward ensuring that the nation’s transportation system will be able to keep up with job growth when the economy does return.
The growing traffic congestion problem is the direct result of politicians refusing to address the underlying problem of a bankrupt Highway Trust fund. Federal gasoline taxes that support the highway system, – 18.4 cents per gallon – have not been increased since 1993 as the population continues to expand and road use and repair costs rise.

The 2011 Urban Mobility Report, published by the Texas Transportation Institute at Texas A&M University, lists traffic congestion in 2010 from several, alarming, ways:
- The amount of delay endured by the average commuter was 34 hours, up from 14 hours in 1982.
- The cost of traffic congestion is more than $100 billion, nearly $750 for every commuter in the U.S.
- “Rush hour” is now six hours of not rushing anywhere.
Congestion is becoming a bigger problem outside of “rush hour,” with about 40 percent of the delay occurring in the mid-day and overnight hours, creating an increasingly serious problem for businesses that rely on efficient production and deliveries.
The economic recession has only provided a temporary respite from the growing congestion problem, according to the study. When the economic growth returns, the average commuter is estimated to see an additional 3 hours of delay by 2015 and 7 hours by 2020.
By 2015, the cost of gridlock will rise from $101 billion to $133 billion – more than $900 for every commuter and the amount of wasted fuel will jump from 1.9 billion gallons to 2.5 billion gallons – enough to fill more than 275,000 gasoline tanker trucks.
“If you invest in roads and transit, you get better service and access to more jobs,” says Tim Lomax, one of the study’s authors. “Traffic management and demand management should be part of the mix, too. Generally speaking, mobility investments in congested areas have a high return rate.”
Loma posits that this connection was well illustrated in the 1960s, when the nation experienced its longest uninterrupted expansion in history, fueled in part by federal investment in the Interstate Highway System.
This theory is not without its critics of course, who maintain that increased dependence on highways is a viscous cycle that sees highway building as the cause of urban sprawl, which requires more highway building and more miles driven, which means dependence on oil imports from nations decidedly hostile to the U.S., which in turn requires a ruinous defense budget and unfunded wars, which drive up the deficit.
It is true that the interstate highway system grew rapidly from the late 1950s to the mid 1980s and the U.S. economy grew along with it. Since then, growth in the interstate system has virtually stopped.
“The only way U.S. companies have been able to keep their products competitive in the face of increasing traffic congestion and rising transportation costs is to squeeze every ounce of efficiency they can out of their supply chain, says TTI Research Scientist David Ellis. “But there is a limit to efficiency and without additional transportation capacity, transportation costs will increase significantly. The result will be higher prices and lost jobs.”
The UMR uses traffic volume data from the states and traffic speed data from INRIX, a leading private-sector provider of travel time information. The combination produces a thorough and detailed illustration of traffic problems in 439 U.S. urban areas.
“Congestion does more than choke our highways, it chokes our economy, making it harder to buy what we need and harder to keep or find a job,” Lomax says. “That’s a bad thing – especially when our economic recovery is so fragile.”
The most economical and effective congestion solutions involve traditional road building and transit use, combined with traffic management strategies such as signal coordination and rapid crash removal, and demand management strategies like telecommuting and flexible work hours. Land use and development patterns can play a positive role, as well, the study claims.
The researchers stress that there is no single best way to fix the problems. The best solutions, they say, will come from efforts that have meaningful involvement from everyone concerned – agencies, businesses and travelers.
