Nashville plans for a big boost in local transit, and is hoping its voters will step on board

» The city’s mayor has announced a multi-billion-dollar plan that would bring new light rail and bus rapid transit routes to the city’s core, but critics are suggesting it won’t work. It depends on the design.

Nashville is booming. The region that encompasses it is growing by an average of 100 people a day, and the rhythm has held up for several years now. The combined city-county Nashville-Davidson has added more than 60,000 residents since 2010 alone.

Developers are catching up, constructing thousands of new residential units, office buildings, and other projects; much of the development is happening downtown.

Yet the city’s transportation system isn’t made for the growth. The highway system is bottleneck-after-bottleneck, and the transit system is underfunded and underused.

Nashville Mayor Megan Barry’s hope is to offer an alternative through a massive new transit program that she announced in October. It would rely on voter-supported tax increases.

But the proposal could face the same problems previous Nashville transit efforts have—namely inadequate public support and vocal opposition. These opponents, as I describe below, are relying on inadequate and deceptive claims to critique investment in transit, but they’re right that the system won’t automatically be effective in attracting riders. Nashville needs better transit, but it’s got to design its system appropriately if it’s going to work.

Fixed-guideway transit for Nashville

Mayor Barry’s plan is to have the city’s voters approve a significant increase in four local taxes in a May 1 referendum. The proposal would increase the sales tax incrementally and add surcharges on existing hotel, rental car, and business taxes. Funds would raise enough to fund $5.4 billion in capital investments, plus a billion more in operations costs over the next 14 years, when construction will be completed. That’s not as large as Los Angeles’ or Seattle’s 2016 referenda, but it’s a big investment in a much smaller metropolitan area.

Indeed, Nashville’s plan would be enough to provide the city’s almost 700,000 inhabitants a large new transit network, encompassing 26 miles of light rail, 25 miles of bus rapid transit (BRT), and significant improvements to the existing bus service and Music City Star commuter rail line.

Lines would largely extend out from downtown, where a $936-million, 1.8-mile transit tunnel would separate trains and BRT services from street traffic. It would make Nashville the fifth U.S. city to invest in a modern light-rail downtown tunnel, after Buffalo, Seattle, Los Angeles, and Dallas* (like Seattle, it will include both trains and buses).

As the map below indicates, light rail lines would extend northeast along Gallatin Pike, west along Charlotte Avenue, northwest along a former rail line, and southeast along Murfreesboro and Nolensville Pikes, all major arterial routes. Four BRT corridors would fill in the gaps. The result would be an urban core generally well served by fixed-guideway transit services.

As currently described, the network would feature relatively high-performance light rail corridors, “traveling in their own lanes,” with transit signal priority and frequent weekday service. The trains would begin running 2026, with full completion by 2032.

The rapid bus corridors, which would be implemented more rapidly, would be electric, have limited stops, also feature transit signal priority, and, “where feasible and supported by the community,” include dedicated lanes and off-board payment.

In sum, the network is projected to attract significantly more riders than the existing regional network, which carries about 33,000 daily bus riders and 1,200 commuter rail users. The city estimates that the rapid bus corridors would see between 9,600 and 11,600 boardings a day and the rail corridors between 61,100 and 71,400. If these projections are realized, the city’s system will carry more riders per mile than those in Charlotte, Dallas, and Denver, and it would more than double existing use of the system.

Over the 2018 to 2032 construction period, about $900 million, or about 10 percent of the total, would go to operations and maintenance costs, with the rest paying for the massive expenditures related to the new rail and bus lines.

That’s a very capital-heavy allocation of resources, and it has its limitations. Light rail service on weekends, for example, would only be scheduled for every 30 minutes. And some local buses would continue to provide service only every 30 minutes, at best. But a new Frequent Transit Network would offer service every 15 minutes or faster on the 10 busiest bus routes, which would have significantly longer hours and an expanded fleet.

The opposition

Assuming these outcomes play out as planned, should the voters endorse Nashville’s proposal? Would the city be getting its money’s worth?

For critics of the project, massive investment in transit simply doesn’t make much sense. Vanderbilt University Associate Professor of Economic Malcolm Getz epitomizes the opposition, and he has produced a lengthy critique that’s been used by local media as evidence for the proposal’s failings. A few years ago, Getz was a key opponent of Nashville’s proposed Amp BRT line, which ultimately failed in the face of state legislative and local business opposition.

Getz’s arguments are similar to those used by most opponents of transit investment in cities across the U.S.: For one, he argues, transit does not reduce congestion and in fact may make matters worse if trains or buses take space away from cars on the street. Two, transit is slow because it requires transfers and thus will not increase ridership. Three, the benefits would go to just few people (since most people don’t use transit), and transit would accelerate gentrification. And four, the availability of new types of car services, combined with tolled express lanes, actually would be more beneficial.

These claims—like many of the popular criticisms of transit—mislead, simplify, and contradict.

It is true, as Getz notes, that the fundamental law of road congestion means roads will fill up to their capacity, so more transit is unlikely to reduce congestion in itself. But evidence does, in fact, show that transit plays an important role in reducing overall automobile traffic, even in places like Nashville where it accounts for a small share of commuters. As such, improving transit service can be an essential mechanism to move more people around a city without having to build more highways.

Getz suggests that eliminating automobile lanes for dedicated lanes for transit will exacerbate congestion by forcing the same number of drivers into fewer lanes. But such reductions in vehicle traffic have been shown either to have minimal impact on roadway capacity or actually reduce the number of people driving. Just as importantly, transit can carry a lot more people in a lot less space than automobiles on roadways.

Of course, transit can only be effective if it’s carrying people, and that’s a shortcoming that Getz relies upon throughout his criticism. He suggests, to summarize, that there’s virtually nothing that can be done to attract people onto the region’s trains and buses because they are slow and require transfers, and thus that those vehicles will be empty no matter what.

But there are ways to make transit effective—it’s just that Getz isn’t much interested in them. As noted above, he’s opposed to dedicated lanes, but those are essential for speeding up transit and actually making them competitive with cars. Nashville’s transit system is quite low-ridership today, but one reason for that is that the service it provides is slow and infrequent, exactly the deficiencies this transit plan is designed to address.

Getz’s claim that Nashville’s transit system simply won’t be well used, and thus does not deserve significant investment, is simply a reflection of existing conditions and an unwillingness to believe that cities have the capacity to change.

Moreover, he is willing to use an argument that contradicts his other claims—that transit will induce gentrification by increasing property values near transit stations. Why, though, would transit improvements increase values if no one is using the system? There is significant evidence that transit investments increase surrounding property values, and the reason for that is that transit improves accessibility. In other words, you can’t both argue that transit won’t be used and that it will increase gentrification.

Getz’s proposed solutions include increasingly relying on ride-hailing services and putting buses in tolled express lanes on Nashville’s highways. Yet encouraging people to take Uber or Lyft into downtown wouldn’t do much at all to solve congestion—in fact, it might make it worse if people are subsidized to take those vehicles instead of the bus. Moreover, given that such services are hardly self-supporting today, and far from inexpensive, it’s hard to see this approach as effective in the long term.

While tolling expressways might be effective in cutting down on traffic, putting the buses there instead of on arterial surface streets would essentially remove transit from the places where it can actually thrive: In walkable, relatively dense neighborhoods, and relegate it to an automobile-dominated corridor.

Plus, Nashville’s massive growth requires new transportation capacity. Simply tolling some highway lanes won’t actually increase the ability of the region to handle more people. That’s why it’s so important that transit investments be offered as an alternative.

What future for the city?

Despite the limitations of Getz’s arguments, they are getting play in the local press. One reason for that is that there are reasons to be skeptical of the potential for Nashville transit improvements.

The city is incredibly sprawling, with a population density of just about 1,300 people per square mile—far less than what is typically needed to make fixed-guideway transit effective, which is something in the range of 10,000 people per square mile. I’ve written critically of the previous transit proposals in Nashville precisely for this reason. Along the proposed lines, densities are higher—3,000 to 4,000 people per square mile, but still pretty low.

As such the city should be focusing intensely to construct larger projects along the routes and downtown to ensure that the transit investment is worth it. The existing land use code also has high parking requirements—at least one space per unit for residential uses, and one space per every 200 to 300 square feet for office uses—that should be eliminated to support a transit-focused city.

This plan is better than the previous one, focusing more on improving transit in the center, where it is likely to work best. Whereas the previous proposal would have extended light rail 30 miles from downtown, this one goes, at most, about seven miles from there. While the city extends roughly 15 miles from downtown, the underdeveloped, exurban parts are not to be served by this plan. That means that it’s designed to encourage development in the core by capitalizing redevelopment of existing built-up areas. That’s the right approach.

The inclusion of a transit tunnel downtown is a radical, expensive approach, but it’s ultimately a good idea from the perspective of making the system as effective as possible. By separating trains and BRT services from traffic, the system will avoid the pitfalls of places like Portland, where light rail vehicles crawl through downtown, and make it far more feasible for people to travel from one side of the city to another.

Moreover, the plan’s opponents are missing the larger issue: This transit plan isn’t really about responding to Nashville’s current travel patterns, for better or worse. It’s about creating a framework for the future development of the city around a reliable transit system.

If the proposal is successfully implemented, it will make it possible to have a transit-oriented life in a city where living without a car is now virtually impossible. It will create the groundwork for an alternative mode of development than the parking-heavy construction that currently dominates.

Despite the vocal opposition, Nashville’s citizenry may, in fact, be willing to go along with Mayor Barry’s transit proposal. It’s a big ask, and it will hit people in their pocketbooks, but the city’s residents are hardly arch-conservative; they voted 60 percent for Hillary Clinton in 2016 despite her winning only 35 percent of the statewide vote.

Even if they vote for the referendum, though, the way the transit projects that are funded by it are ultimately designed will play an essential role in determining their effectiveness. The fact that the city is proposing to include dedicated lanes only where “supported by the community” suggests that the city’s leaders are already anticipating opposition from neighbors in places such as along the West End corridor, which connects downtown to Vanderbilt University, and where the Amp project met its demise a few years back. But the transit services will only be useful for people in the city if they’re designed to be as rapid as possible.

Better transit for Nashville, then, means more than just passing new funding for the city’s system. It means making sure that the projects built are designed to work and to actually attract riders. That’s the really difficult part.

* Several cities, including Boston, Cleveland, Newark, Philadelphia, and Pittsburgh, built light rail tunnels many decades ago and have kept them operating. Tunnels in Dallas and Los Angeles are planned or now under construction.

In response to growth, Chinese cities choose metros

» With rail rapid transit construction in virtually every major Chinese city, the country is betting on an urban future focused on transit.

Faced with limited political will for increased infrastructure funding, the debate over transportation planning in the United States has become increasingly dominated by an austerity-driven understanding of how to respond to growth. Unwilling or unable to develop ambitious plans for the future, many cities and their public officials have contented themselves with doing more with less.

Doing more with less is a strange maxim for an incredibly wealthy—and still growing—nation. Nevertheless, it is a pathology that has so altered many American planners’ sense of the acceptable that the mere idea of a master plan of significant investment attracts little more than dismissive scoffs. With blasé planners and uninterested politicians, “doing more” is readily transformed into actually doing very little.

Undoubtedly the overwhelming problems that infect that very core of the American

A year into the Trump Presidency, federal transit support limps along

Minneapolis Southwest Corridor

» Despite efforts by the administration to eliminate support for new transit projects, they continue to be funded by Congress—and transit agencies are continuing to act as if they’ll see aid far into the future.

Last March, the Trump White House released its budget blueprint, a document designed to articulate the administration’s orientation toward the executive agencies. The blueprint took a radical stance toward the federal government’s involvement in transit: It proposed a wholesale elimination of the capital grant programs, which fund a portion of costs for rail and bus guideway projects around the country. It suggested doing away with the TIGER discretionary grant program, which is frequently used to fund small-scale bus rapid transit and streetcar routes, as well as transit stations.

The budget also offered no remedy for the upcoming depletion of revenues from the federal gas tax, which has not been increased since the early 1990s, thereby

Openings and Construction Starts Planned for 2018

» Despite significant hostility from the Trump Administration, cities are pushing ahead with major new transit projects nationwide. Here’s the annual roundup, with dozens of projects on the way with planned openings in 2018.

In 2018, 340 route miles of new fixed-guideway transit projects, representing a total investment of $13.2 billion, are expected to open for riders in the U.S., Mexico, and Canada. An additional 366 miles of lines, costing a total of more than $75 billion to build, will be under construction in 2018 but are planned for opening in later years. The continent’s cities, then, continue to be active sites of expansion for relatively high-quality transit improvements.

Projects are described in more detail below. They’re also accessible on the updated Transit Explorer map and database, on which it’s possible to view project routes, stations, and details throughout North America.

This is the 10th year of my compilation of new transit projects

In a simple move, Toronto transforms a streetcar line into something far more useful

» The city’s King Street Transit Pilot is preventing cars from using the street as a throughway. In doing so, it’s showing how other cities might prioritize transit on their busiest streets.

With almost 300,000 daily riders, Toronto’s streetcar system is the most-used light rail network in North America. Unfortunately, for many of its riders, it’s not a particularly pleasant experience.

That’s because most of its streetcar lines operate in a right-of-way shared with automobiles, slowing the system to a crawl. It’s a misery unfortunately shared with most of the new streetcar lines now existing, under construction, and planned in the U.S.—and, perhaps more importantly, with virtually all bus routes.

This week, Toronto has begun piloting one solution.

It has substantially improved streetcar service on a portion of King Street, which runs roughly east-west through the densest portion of the city’s downtown. On the 1.6 miles between Bathurst
