Neglected Cities Push Certain Transit Because Regional Agencies Won't

In the middle of all the wrangling over the Cincinnati streetcar Peter Rogoff, who is the FTA administrator, said something really interesting in his letter to the city and transit agency. The transit agency (SORTA) is the fiduciary agent for the FTA funding pass through to the city and wants to stay on the FTA's good side since they receive other federal funding. The mayor is looking to kill the project for who knows what reasons he set his mind to, but this is really kind of an aside.  Rogoff:
Transit improvements are best deployed when they are governed and controlled 'under one roof.
He goes on to say in his letter, relayed by the Cincinnati Business Courier
While FTA has been successful in supporting transit projects that are not controlled or operated by the region's principal transit agency, we have found that there are a great many economies of scale that better serve the taxpayer when a fully staffed and experienced transit provider is involved from the very beginning
But isn't that part of the problem?  These massive regional transit agencies are typically stacked with suburban board members that don't always have the core cities needs at heart.  They are usually concocting schemes to extract money or service in some form or fashion from the more transit willing neighborhoods in the region in order to have some sort of suburb to city dream bus or commuter rail line that costs a lot, but really doesn't move the needle on changing mobility in a meaningful way.  Either that or they have to have an election that includes heavy transit opposition precincts that sink ballot initiatives that pass in the city proper.

So recently cities have been taking on the mantle of thinking up and building transit that works for them and their goals.  Portland, Cincinnati, Austin, and others have all taken up planning for more urban transit options and with much different goals.  At the start of the Portland Streetcar process, Tri-Met wanted nothing to do with it.  They were a regional agency.  Right or wrong, the city streetcar movement is a function of the neglect that center cities feel when it comes to regional transit priorities.  The core might be the economic engine for the region, but the fiscal extraction continues.

This is also a disappointing admission that transit agencies and their federal funders still don't know their role in city building.   I'm not talking about building a streetcar and waiting for housing development to come, but rather the need to economically serve, connect, and bolster regional employment centers with workers in a more productive way than the single occupancy car. 

Today an NPR story on Austin popped up with TTI's Tim Lomax stating that it wasn't building roads or transit that needed to change, it was people's behavior. 

But Lomax says his computer models show the only real solution is going to involve changes in behavior and lifestyle. "We did some modeling to suggest the kind of magnitude of change," he says. "We used a giant hammer on the travel model. We took away 40 percent of the work trips. We said those are going to happen somehow, but they're not going to happen in a car." To keep traffic flowing in his sophisticated models, Lomax plays God of Austin. "We said, instead of people driving on average 20 to 25 miles to get to work, now they're going to drive five, six or seven miles to get to work," he says. "That says there's going to be a massive shift in jobs and population."

Emphasis mine.  Those other 40% of work trips that would be needed to keep traffic flowing green (which would never happen - induced demand, duh) would come from walking, biking, and transit because the employment cores were adequately served with good transit. 

What we continue to see today is an overly regional approach to transit development based on a suburban fantasy of living where you want and commuting into work downtown.  Most people don't work downtown.  But intensification of core neighborhoods strengthens the tax base.  So what you get is like what is happening in Minneapolis.  The transit agency is trying to fund commuter service that they call light rail while the city thinks of streetcars because they don't have the funding power to do more.  But there is no talk of dedicated lane surface light rail or subways that only go to the edge of the streetcar suburbs because that doesn't fit each side's worldview. 

The FTA seems to be on the suburban side of the issue, allowing, even wanting, these commuter systems that end up being really expensive to operate (See Northstar in the Twin Cities) with somewhat limited value at this point in their transit network development.  If the FTA can't figure out the suburban leaning of transit agencies or the need to feed employment centers better, we're going to keep traveling down the same choked road, and it won't be pretty.

My Basic Reasons Why I like a Guadalupe Lamar Alignment


While I don't quibble with the need for expanded capacity on Riverside, I will argue that Guadalupe/Lamar is a superior route for urban rail in north of Austin's core, over a possible Highland corridor.  I'll let others deal with the methodology issues in Project Connect's selection process, but for me, the data is clear that this corridor is superior for the following reasons...

1.  CORE IS CONSTRAINED

While there are many laudable goals for building urban transit including housing and office development, the main reason for building a rail line is to increase the capacity of a road such that more people can get into a constrained space.  Dan Chatman at the University of California at Berkeley  and others have found that rail's key economic development benefit is serving to increase agglomeration effects in employment centers. 

These agglomeration benefits, as the article states, basically mean the ability to match skilled workers with employers that need them.  Sometimes the definition of economic development gets reduced down to actual development of buildings, but for transit and actual regional economic development, it means much more than that.  Allowing the core to densify and increase the tax base without increasing congestion or at least making travel times reliable, leads to greater access to a skilled workforce at all wage levels.

This is currently happening in the Warner Center in Los Angeles and Tyson's Corner in Virginia.  The constraint to employment center growth is limits on auto access, so now landowners and policy makers introduce high capacity transit to get more people of all skill levels to their jobs and to increase the public and private productivity of the land.

This goal is in tandem to providing affordable housing, mixed income housing, and reducing transportation costs but ultimately it is one of the main reasons to build transit, to continue the increased benefits that downtown's economic engine brings to the city and region as a whole while giving more people access to those benefits.

So if the core is constrained, what is the best way to make travel easier to the most people such that they can reliably access jobs in the core as it grows?  In other words, how do we feed more oxygen into the fire.  Austin's current bus network does a good job of this, but certain corridors are constrained and need to be expanded.  But you can't expand roads in those corridors so you need to expand the number of people who can travel in those corridors, hence high capacity transit. 

2.  RIDERSHIP

The answer to where you'll be able to pull the most oxygen to feed the fire is where they will be the most riders. Riders matter for two reasons, first it makes your line more cost effective from an operational standpoint.  Currently the highest ridership bus line in the city by a long shot is the #1 on Guadalupe and Lamar.  According to data from the service plan 2020 report, this corridor suffers the most in terms of on time performance. In fact that 2010 report noted that the bus was on time only 49% of the time

But the more riders you have on the line, the more you can justify per passenger the operational cost.  Portland has done a great job with their light rail cost efficiency and has proved many times that compared to the bus network, the light rail network is a more efficient way of moving people in and out of downtown.

The second reason ridership matters is that if you're going to be seeking funding from the FTA, you're also going to be competing against every other region in the country seeking federal funds.  In the Transit Space Race report I noted that it would take 78 years to fund all the lines that are being planned with the current federal funding levels of $1.6B per year.  That number has actually been lowered because of a stingy congress, but it's still a very small number, especially when you're helping to build multi-billion dollar subways in New York and San Francisco. 

So what is the best way to win funding?  In part its selling to the FTA that you have all your land use planning in place and have thought a bit about economic development.  But they want to give a project justification rating, an overall rating, and you have to compete with lines like the LA downtown connector that are projecting 16,000 new trips out of 88,000 riders. 

I highly recommend taking a look at other projects that are ahead of Austin in line for federal funds.  Also, going back in time, the Austin line in 1999 scored very high against places that are now built including Houston and the Twin Cities - The Lamar line, which had pieces of the current Metro Rail line would have had 37,000 riders.

So what is the biggest thing that any light rail line can do to get more riders?  Connect people with jobs.

3.  THE IMPORTANCE OF JOBS
Connecting jobs with transit drives ridership.  We know this from research done by Zupan and Pushkarev, Gary Barnes, and UC Berkeley's TOD guru Robert Cervero.  Considering over 59% of transit trips are for work, this becomes an important point.
Pushkarev and Zupan in 1977's Public Transit and Land Use Policy - "Enlarging downtown size or raising nearby residential density. Suppose the options are to double the size of a downtown from 10 to 20 million square feet, or to double the residential density within a few miles of it from 15 to 30 du/acre. The former will increase per capita trips by transit three to four times more than the latter." Many more can be found in this post on the blog

This from Gary Barnes - "Using regression analysis, he showed that in Minneapolis, aside from developing residential densities, transit share can be increased by building up commercial centers. In the regression, he showed that for every 1000 people per square mile that the residential density grew, the increase in transit's share to downtown increased 2.4% versus .6% increase when people went to suburban jobs."

So what does this tell us?  That trips increase when you connect places of density in a city to a strong downtown.  But it's not just downtown that matters, it's all jobs along a line that build ridership.  I created this chart below from my TRB paper on light rail ridership.  It shows new light rail lines that were built in the last 10 years.  What makes their ridership go up?  Connections to jobs. Now in the paper I discuss many of the other issues that folks above mention as well including restricted parking downtown.  But jobs seems to be a clear cut connection that's fairly easy to see, and backed up by a lot of the literature.

So jobs matter for ridership, and connecting more jobs within a half mile of stations will get you more riders.  So ignoring the core of UT, Capital Complex and downtown, where are the most jobs outside of downtown in the northern corridors that are being compared.  Well of course on the Guadalupe/Lamar corridor.  This data was taken from the 2011 census LEHD dataset.  The North Lamar corridor to Crestview has at this present time 46,275 jobs within a half mile.  26,400 of them are people making less than $40k annually.   Contrast that with a likely Highland Corridor, and you see less than half the number of jobs.  Even with rosy projections and development on that corridor, where would 25,000 jobs come from?

This is part of the reason people are so upset at the process and selection.  Sure it's about congestion and redevelopment and serving low income communities.  But congestion is where the jobs are located.  Redevelopment actually happens on light rail proximate to jobs as well.

4.  WHERE DEVELOPMENT HAPPENS ON LIGHT RAIL
We know this because CTOD did a study called Rails to Real Estate, which looked at development patterns along three new light rail lines in Charlotte, Denver, and Minneapolis.  What this report says is that light rail doesn't just create ridership out of thin air, a lot of public policy has to take place but also that the market drives a significant pattern of development. 

There are maps in the report that show where development happened along these lines, but its best to describe it as the employment gravity well.  Basically the market for denser development is in major employment centers, and that market gets extended from the gravity well by the rail line.  It's not just downtown because Denver's line connects the Tech Center, which is the second largest employment cluster in the region, and it saw an uptick in development as well.  Take a look for yourself.  Alignments go away from downtown from left to right.
Twin Cities Hiawatha Line



Denver Southeast Corridor


Charlotte's South Corridor



This is obviously a small sample size of new lines but it is quite instructive.  The location of major employment drives development and redevelopment because the transit is extending the market, not creating it.   Putting a line up into the Highland sector might help spur a small catalyst of development, but its proximity to downtown or a major employment center that matters most.  Guadalupe and Lamar have much more employment along the corridor which is likely to give more people more options to connect with places they work and places they want to go.  But it's the straight line that matters a lot too.
5.  BE ON THE WAY
Anyone who knows Jarrett Walker's work knows that he likes transit lines to be straight.  This causes less schedule disruption and makes the line faster and more reliable.  In the back and forth on twitter he noted the jagged lines that would likely occur if we built the Highland line, especially the section through UT.  You can see in the map above how hard it would be to get from one point to the other without having to make turns somewhere.  But its not straight.
Additionally, we know from UC Berkeley's research that for people to use the train, employment is best closer to the stop, than further away.  People are more likely to use transit for work if it's within a quarter mile, while taking it from their homes is likely to be acceptable to walk a half mile.  This means the route that travels through a less used part of UT, by all the parking garages near the Capital (even though there will be a med school there) and less inviting pedestrian places like Airport Blvd, is less likely to drive ridership.  Now this might be redeveloped in the future.  But we know where people go now, because they take the #1 bus to get there. 

Aerial-Alignments-North

So this is my case. As a national transit advocate, bad decisions in locations make it harder for us to fight for more funding against those who oppose us.  Killer ridership lines are great for beating back the forces against us as well as giving future leaders support for expansion.

Remember
1. The Core is Constrained
2. Ridership Matters for Operations and Funding
3. Ridership is Tied to Employment Location and Density
4. Development and Redevelopment Happens Near Jobs Now
5. The Straight Line is the Best Line
