Really, fixing traffic comes down to getting a whole lot of people to get to and from places differently than they always have.

You need to change driving behavior, whether you offer options and count on enough people using them to make a difference– mass transit; or you punish and coerce people into driving how you’d like– giving tickets, making certain lanes into toll roads; or you offer rewards to people for doing what you want. And so on.

There are endless infrastructure changes that might be done– lanes added, rail lines built– but in the end, the way people move from one place to another has to change.

In the first part of this three-part series outlining alternative arguments for fixing traffic, the lay-of-the-land was presented: The idea of a regional transit system, with Nashville’s plan being the first and largest part, as a traffic solution has gotten almost all the attention. But there are voices out there that make compelling arguments against the plan, which includes a large investment in light-rail and buses in a spoke-and-wheel sort of transit system.

After all, just because it has gotten the most attention does not mean it will do the most it can to decrease your commute.

Vanderbilt economics professor Malcolm Getz has a highly critical opinion about the plan. It gets things all wrong, he thinks.

His solution: toll roads, and no light rail. Combined with better technology like camera-monitor systems that will control access to toll lanes, Getz argues that toll roads work and that they shape behavior in an age-old way: money.

Getz, who has appeared on a number of panels and authored an editorial or two for the Tennessean expressing concerns about the Nashville transit plan, is fully in favor of converting current HOV lanes to toll lanes to reduce car count and improve traffic flow.

He points out that adding lanes does not address traffic, and TDOT representatives have often echoed that sentiment. If you add a highway lane, it tends to simply fill up and traffic does not decrease in an impactful way. Instead, he argues, it’s all about flow. Currently, HOV lanes are mostly treated as “just another lane” by the driving public.

“Engineering literature shows that if traffic is heavily congested with stop and go movements, if you change one lane to moving at 50 miles per hour, it doubles the number of cars that pass a certain point,” he said.

“If you made the HOV lane into a toll lane, where the fee might be $.50 cents per mile or more, with restricted entrance points and maybe some simple, inexpensive markers, like permanent road cones,” Getz explained, “..then Bingo! Overnight, the HOV lane becomes a toll lane and it would work like it is supposed to, without the trouble of added enforcement, and traffic would flow much more freely.”

“To those who say that only the more wealthy would benefit, the added cost of commuting quickly, on the toll lane, would also make people more likely to rideshare to share the cost, it would incentivize the use of public transportation down the line,” he added.

Dedicating a lane to market forces would open up traffic dramatically and people would pay for the privilege of blasting downtown.

Creating a toll lane is “not an insignificant investment” Getz acknowledges. It would take more than a change in policy or a paradigm shift in individual behavior.

“It would take a revolution,” explains Mark Cleveland, Nashville’s 2014 Entrepreneur of the Year. “Toll lanes are not legal in Tennessee, automated enforcement systems and video cameras are not legal in Tennessee.”

  1. I’m not usually an individual who posts an opinion but as a traveling sales executive who logs more than 50,000 miles/yr, I felt it was time to chime in.
    I recently attended one of the transit plans open houses. The event was reasonably attended but disappointing in that most of the representatives could not articulate exactly what the solution would look like to the general public. The scripted answer received repeatedly was “this is a multiphase plan and a lot of the details need to still be worked out”. For a plan ($5+ billion) that goes to vote in a few months, this answer was inadequate.
    To be fair, there are elements of the plan that are necessary and will be useful at helping many commuters in and out of downtown from limited communities, however, there are also elements that are not being talked about and should be.
    1) The plan offers Minimal or No relief to the car congestion on our interstates “unless” drivers stop driving at the Davidson County line and switch to mass transit (bus or light rail). This seems like a very big “unless” and highly unlikely to think that outside Davidson commuters will freely accept a more complicated commute.
    2) The Light Rail Plan – Overall I believe that rail is potentially one of the solutions that can relieve car congestion on the interstates. However, the proposed light rail system is like stepping back in time. It will lay tracks into our turning lanes and have conductor driven train cars via an electric overhead cabling system similar to San Francisco or New Orleans, but without trolleys. The MTA train drivers will have all of the same traffic challenges as everyone else except they can only start and stop they cannot turn out of the way of a potential accident. Imagine a train longer than two buses in your turning lane, how many stop light changes does that add to your commute? How far does that back you up before you even reach the turning lane?
    If trains are part of the solution, why are we not looking up? How about elevated high-speed monorail above the median over our interstates? Europe, the Far East, New York City, Chicago, and Seattle all have elevated train systems.
    Nashville’s skyline has turned into a beautiful modern city. If the solution is to run miles and miles of electric train cables down our parkways and pikes and not offer any relief to our car congestion, I have to ask if we are we spending these billions wisely?
