Americans are driving less, and fewer Americans are driving, according to a May 14 report from the U.S. Public Interest Research Groups (PIRG), an advocacy organization. For Cincinnati, the trend might justify a recent shift in public policy that embraces more transportation options, including more bike lanes and a streetcar. “Americans drive fewer total miles today than we did eight years ago, and fewer per person than we did at the end of Bill Clinton’s first term,” the report reads. “The unique combina­tion of conditions that fueled the Driving Boom — from cheap gas prices to the rapid expansion of the workforce during the Baby Boom generation — no longer exists. Meanwhile, a new generation — the Mil­lennials — is demanding a new American Dream less dependent on driving.” The report also says U.S. transportation policy “remains stuck in the past” and needs to “hit the ‘reset’ button.” The report, which uses U.S. Department of Transportation data from 2012, found Americans were driving about 9,000 miles a year per person in 2012, down from a peak of nearly 10,000 in 2004. Until the peak, Americans had been driving more miles each year since the end of World War II. The report finds the driving trend at odds with other means of transportation: “On the other hand, Americans took nearly 10 percent more trips via public transportation in 2011 than we did in 2005. The nation also saw increases in commuting by bike and on foot.” The report attributes much of the shift to millennials, members of the generation born between 1983 and 2000, which the report says are more likely to demand public transportation and urban and walkable neighborhoods. The new expectations are largely driven by Internet-connected technologies, which are “rapidly spawning new transportation options and shifting the way young Americans relate to one another, creating new avenues for living connected, vibrant lives that are less reliant on driving,” according to the report. PIRG finds the trend will likely stick as gas prices continue to rise, fewer Americans participate in the labor force and Americans demands less time spent in travel. Even if millennials begin driving more in the future, the report’s findings show Americans are going to be driving much less in 2040 than federal agencies currently assume. “This raises the question of whether changing trends in driving are being adequately fac­tored into public policy,” the report reads. The report concludes local, state and federal governments should react to the new trend by planning for uncertainty, accommodating millennials’ demands, reviewing the need for more highway projects, adapting federal priorities, using transportation funds based on cost-benefit analyses and conducting more transportation research. For Cincinnati, the trend could have implications for two major transportation projects: the MLK/I-71 Interchange and the streetcar. The streetcar project uses capital funding sources — some uniquely tied to mass transit projects — that some opponents argue should be reallocated to support the MLK/I-71 Interchange project. But the report’s findings seem to support the city’s current plans to push forward with mass transit projects like the streetcar, even while local funding for the MLK/I-71 Interchange project remains uncertain. After making changes based on feedback from public meetings, the Ohio Department of Transportation priced the interchange project at $80 million to $102 million, or $10 million to $32 million higher than the previous estimate of $70 million. The higher price didn’t lead to the same outcry that resulted from the streetcar project’s $17.4 million cost overrun, likely because of the interchange project’s broader support, secure state funding and feedback-driven circumstances. Still, the city could share some of the higher cost burden for the MLK/I-71 Interchange project. Previously, the city planned to use funds raised by leasing its parking assets to the Port Authority for the interchange, but that plan is currently being held up in court. In 2012, the city adopted Plan Cincinnati, the city’s first master plan since 1980. The plan advocates for more alternative methods of public transportation, particularly light rail and bike lanes. But the master plan does not establish means of funding, so City Council will have to approve funding over time to implement the plan.
