Urban Density, Mass Transit, and Uber

Over at FiveThirtyEight, Nate Silver and Rueben Fischer-Baum claim mass transit is Uber’s best friend.  They use data from New York to show that Uber is most frequently used in areas with effective mass transit. They explain that residents in areas with poor access to mass transit are more likely to assume the fixed cost of car ownership. Once that overhead has been assumed, these residents are more likely to use the personal vehicle they’re already paying for rather than rely on alternative modes of transportation. There’s variation in use depending on the intersection of income level and transit accessibility, but that the big takeaway is that mass transit supports Uber. And that Uber as well as other TNCs will be most successful where effective mass transit is already in place. It’s a great analysis. And it’s partially right–but not entirely.   Mass transit does support TNC growth just as the authors describe. But TNCs, in turn, support mass transit by solving the last mile problem. The two systems are complementary. But without a supportive urban environment, neither system stands any chance of success. Mass transit and TNCs may be allies, but both rely on urban density as their benefactor. Residents in densely developed cities with mixed land use consume less transportation per capita because the distances between work, housing, and recreation are all much shorter. And below a certain level of consumption, the minimum fixed cost of car ownership ceases to make sense. Alternative forms of transportation like a mass transit system or a TNC platform entail only marginal cost, so they begin to look more attractive. Imagine putting a mass transit system–commuter rail, BRT, whatever you’d like–in the middle of Houston or LA style sprawl. It might be a net positive for a TNC, but in no way […]

Engineering in the dark

The similarities of urban design across American neighborhoods is no coincidence, but neither is it the result of city planners’ uniform adherence to best practices. Infrastructure is often built based on shockingly little information about the demands of its users. And while poorly reasoned infrastructure policy in one city is bad enough, the United States’ broad adherence to poorly reasoned policies has resulted in a nation in which swaths of neighborhoods are built on poor design foundations. Parking Requirements In The High Cost of Free Parking, Donald Shoup explains the origin of municipal parking requirements. Municipal planning offices do not have the resources to study the amount of parking that businesses should provide. Even with more staff, it’s not clear that planners would be able to determine optimal parking requirements unless they allowed business owners themselves to experiment and choose the amount of parking on their own in a learning process of how to best serve their customers. The Institute of Transportation Engineers is one of the only organizations that provides estimates of the number car trips that businesses generate. Given the lack of information planners have to determine parking requirements, they often rely on ITE’s information to set their parking requirements. However, ITE studies are often conducted at businesses that already provide ample free parking, ignoring the potential for businesses to manage demand for parking on their property through prices. Furthermore, ITE estimates of trip generation are typically based on a very small sample of locations, which are unlikely to be representative of businesses and cities in general. In the example below, the ITE provides a recommendation for fast food parking requirements based on their floor area. Even though the chart includes a line of best fit for the plot of peak parking spot occupation and floor area, the ITE hasn’t demonstrated a correlation between these two variables. Shoup points out: We cannot say much about how […]

Interview with Alain Bertaud

Alain Bertaud is probably the most interesting urbanist you’ve haven’t heard about. He is a senior researcher at the NYU Stern Urbanization Project next to names such as Paul Romer and Solly Angel. Bertaud used to be the lead urbanist at the World Bank, and Ed Glaeser has said that everything he knows about land use restrictions in developing countries he has learned from Alain. Bertaud has also worked as a consultant and/or resident urbanist in cities such as Bangkok, San Salvador, Port-au-Prince, Sana’a, New York, Paris, Tlemcen and Chandigarh. Our Brazilian collaborator Anthony Ling, editor of Caos Planejado, met Bertaud at the NYU DRI conference last year entitled “Cities and Development: Urban Determinants of Success”, who gave us the following interview: AL: You are currently writing a book tentatively titled “Order Without Design”, which in some way relates to the title of our website, “Planned Chaos”. What do you mean by the title of your next book – what should readers expect of it? AB: “Order without design” is a quotation from Hayek that he uses in a different context in “The Fatal Conceit”: “Order generated without design can far outstrip plans men consciously contrive”. In the context of cities it means that cities themselves are mostly self generated by simple rules and norms applied to immediate neighbors but with overall design concept designed by one person or a group of designers. The spatial structure of large cities is a mix of top-down design and spontaneous order created by markets. Spontaneous order appears in the absence of a designer’s intervention when markets and norms regulate relationships between immediate neighbors.  Most evolving natural structures, from coral reefs to starlings’ swarms, are created by spontaneous order. The objective of my book is to show that top-down design should be reduced to a minimum and much more room should […]

BART, Josefowitz, and Mass Transit in the Bay

Last week, Nick Josefowitz unseated a multi-decade incumbent for a spot on the BART board of directors. Normally I don’t pay too much attention to elections, but Mr. Josefowitz might actually have some good ideas. For everyone outside the Bay Area, the BART (Bay Area Rapid Transit) system is a commuter rail line that constitutes the vital transportation link between the East Bay and San Francisco. On a typical weekday it provides 400,000 rides and that number is increasing as the regional economy continues to boom. Suffice it to say that BART is a big deal to a lot of people who rely on it every day (myself included). While Josefowitz’s campaign website talks about cleaning up dirty stations and increasing late night train availability, I had the privilege of hearing him outline an interesting proposal during a private, small group discussion some months ago. According to Josefowitz, BART sits on a substantial amount of real estate in the form of station parking lots. His proposal was to repurpose some of this space as high density housing. This would help with the region’s housing shortage and support BART ridership by clustering population around the system’s stations and the lost spots could be offset by building parking structures on the remaining lot space (many BART parking lots are ground level only as opposed to multi-level parking structures). This sounded a lot like Hong Kong’s integrated rail-property development approach which has proven to be an unqualified success, so my interest was definitely piqued. As always, there’s plenty of which to be skeptical. The fact that the proposal was brought up in a private discussion, but isn’t listed on the campaign website may say something about where it falls in Josefowitz’s priorities. Also, it’s difficult to tell how effective the incoming director will be […]

How Hong Kong Pulls Off Transit Oriented Development

Integrating rail and property development is the cornerstone of the MTR’s success. In the U.S., coordination between transit authorities and developers tends to be mediocre at best. In Hong Kong, however, the MTR is both the transit authority as well as the property owner, and this makes all the difference. Coordination Problem Most attempts at transit-oriented development in the U.S. involve multi-party negotiations. The agency responsible for the transportation system haggles with different developers interested in undertaking projects along the line. Instead of implementing a unified plan, the transit agency has to negotiate specific agreements with each developer. And, because the priorities of the transit agency and the developers are never perfectly aligned, development agreements become subject to second-best compromises. Further, any disputes that arise once significant capital has been committed are costly to resolve. This arrangement makes leveraging land values difficult as well. Developers frequently get tax breaks as an incentive to undertake projects. Whether abatements on property tax or straight-forward rate reductions, tax incentives typically preclude the use of land values to help fund transit. And, even without special incentives, major property owners who stand to benefit from proximity to a transit system have every reason to resist tax increases of any kind if there’s a chance of free-riding. The MTR, on the other hand, uses the integrated rail-property development  approach which combines the two roles of landlord and transit developer. The MTR owns the right-of-way as well as the surrounding properties. This removes the necessity of extended negotiations, having to settle for second best solutions, and the potential downside of disagreements partway through a project. By combining the functions of landlord and transit developer, the MTR is also able to internalize land values. The rail line drives up the value of the MTR’s properties and that value covers […]

Why No One Drives to Work in Hong Kong

Need to get 4 million people to the office every day? Hong Kong has you covered. The Mass Transit Railway (MTR) is a rail system in the city of Hong Kong, currently managed by the Mass Transit Railway Corporation Limited (MTRL). The system opened in 1979 and now operates over 135 miles of track as well as more than 152 stations in Hong Kong. The average trip costs somewhere between .50 cents and $3 USD, and the system makes back 186% of its operational costs on fares alone. Much of the system’s success can be attributed to urban density. Denser development means people live, work, and play in smaller geographic areas, meaning that more people are travelling between a fewer number of points. This is a huge plus for a fixed-route system like a railway. The MTR, however, hasn’t been a passive beneficiary of its environment. The MTR owns real estate around each station in the system and integrates rail and property planning so that the development of one supports the development of the other. Construction around each MTR station is incredibly dense, so it can put as many potential riders as close to a station as possible. Over 41% of the population in Hong Kong (2.78 million people) lives within a half-mile of a station. Additionally, the company’s real estate strategy emphasizes walkability; some residents of MTR owned properties can walk from their homes to a station entrance without ever even going outdoors. Clustering potential riders around each station–and making sure passengers have an easy time getting there–helps support high levels of ridership. While fares cover the costs of operations, it’s really property development that pays for maintenance and expansion. The rail line, in turn, increases the property values of parcels adjacent to each station. This augments the land […]

The importance of driverless trains

As Honolulu is making progress on its driverless elevated rail system under construction, Washington, DC is finally beginning to return to computer operation on its red line after a 2009 crash brought an end to reliance on the computerized system. While the move in DC will facilitate smoother driving and braking, WMATA still relies on train operators in the cabs, forgoing the cost-saving opportunity that driverless systems provide. It’s difficult to overstate the importance of driverless trains in the effort to bring U.S. transit operations down to a reasonable price. Driverless systems currently operate successfully in cities from Vancouver to Algiers, and the world’s most financially successful intracity transit systems in Hong Kong and Tokyo have embraced the technology. In spite of WMATA’s high profile accident that happened while the trains were computer-operated, a well-designed driverless system is actually safer than human operated one. Driverless systems offer a better ride quality, stay on time, and face a lower marginal cost of extending service hours. Labor costs make up huge shares of U.S. transit systems. In DC, for example, personnel costs make up 70% of the agency’s operating budget. In 2010, WMATA spent $38 million on the salaries of 611 train operators, and this does not include their retirement and health benefits. In New York, personnel costs make up $8.5 billion of the agency’s $11.5 billion operating costs, and in Chicago labor takes up 73% of CTA’s operating expenses. Obviously not all transit workers jobs can be automated (all of these systems have more bus drivers than train operators) and some operating costs would rise under a driverless system. But taking steps toward reducing labor — that comes at a premium in high-cost-of-living cities where transit is most important — is crucial for reducing transit’s operating costs and making transit systems financially sustainable. In all sorts of industries automation […]

Six Shooters and Bullet Trains: High Speed Rail in Texas

California might have some competition in the race for high-speed rail. Texas Central Railway wants to begin construction on a high-speed line from Dallas to Houston as early as 2017. The current plan is to go from downtown to downtown, with possibly one stop along the way in College Station. An environmental impact assessment is under way and the hope is to be operational by 2021. The company claims that the price per ticket will be competitive with airfare and that the run will take a mere 90 minutes. To give that some context, current travel time from Houston to Dallas by car is about 3.5 hours according to Google (but closer to 4.5 according to my prior experience). While there’s a lot to be skeptical about here, the impact of connecting the nation’s 4th and 6th largest urban economies could be significant. If a high-speed line does get built and if it does manage to deliver on its specs (two major “ifs” already), it would be the equivalent of a magic portal…or a stargate…or a warp pipe…or a tesseract…or…well…the point being it would make the two places functionally much closer together, and that’s a big deal. Cities become economically vibrant through agglomeration. Bringing people closer together lowers search costs for both employers and employees. It also increases the likelihood of “creative collisions”. What high-speed rail could do is combine the benefits of agglomeration that each of these two cities already enjoy. And, as early in the day as it is, there’s already speculation that a line connecting Dallas and Houston would be a precursor to additional lines connecting all four of the state’s pillars of civilization: Dallas, Houston, San Antonio, and Austin. The unbridled optimist in me imagines high-speed rail as the embryonic bones of a future mega-city encompassing […]

DC streetcar: Worse than nothing

On Tuesday, DC’s city council passed a tax reform package that will cut funding for future streetcar construction. These cuts come as the H Street streetcar delays continue to mount, and much of the commentary supporting the streetcar has shifted from touting its transportation benefits to its economic development role. As Stephen has explained, the benefits of streetcar over bus depend heavily on streetcars having dedicated lanes, which most of DC’s streetcars wouldn’t have. Earlier this spring, I was in a bike accident that cemented my opposition to DC’s streetcar. Because the streetcar tracks cover the right two-thirds of H Street’s right-hand lanes, bicyclists typically ride between the two tracks. This creates a situation in which the sudden need to swerve or a brief loss of concentration puts cyclists at a risk of catching their front tire in the track, causing an over-the-handlebars accident when the front wheel comes to a sudden stop. In Toronto, streetcar tracks are a factor in nearly one-third of serious bicycle accidents. While I can say I’ll now go to great lengths to avoid riding on H Street, DC’s lack of good east-west bike routes make it unrealistic to expect all cyclists to avoid the streetcar tracks. Avoiding tracks will be much more difficult for cyclists under DDOT’s plan to eventually construct 22 miles of tracks. Aside from creating a hazard for cyclists, this streetcar will only provide effective transportation for people visiting H Street retail destinations from the adjacent residential neighborhoods. It does not connect residential neighborhoods to job centers. While some have argued that it’s designed to serve tourists rather than District residents, the streetcar line doesn’t pass by any sightseeing, I don’t think that H Street’s retail is a common destination for tourists. Passengers using the streetcar to travel east from Union Station have to navigate a large parking garage to board the […]

Urbanism without government

Asking, “But who will build the roads?” is a cliched response to proposals for a more libertarian political system. However, it leads to the interesting historical question of “Who has built the roads in anarchic societies?” Colonial America provides a few examples that answer this question. Perhaps the best known example of anarchism in American history was in Rhode Island, or “Rogue’s Island,” founded by Baptists fleeing Massachusetts. The stateless Baptists founded the cities of Portsmouth and Warwick. Unlike the Baptists, William Penn didn’t intend to create an anarchic colony, but Pennsylvania was, in fact, without a government from 1684 to 1691 as evidenced by Penn’s failure to successfully levy any taxes during that time. It’s difficult to know much about street building from this time period in part because of how much time has passed and in part because, as Murray Rothbard writes, “The lack of recordkeeping in stateless societies — since only government officials seem to have the time, energy, and resources to devote to such activities — produce a tendency toward a governmental bias in the working methods of historians.” However, we do know that Philadelphia’s neighborhoods near the Delaware River were growing during this time. One of the country’s oldest continually occupied streets is Philadelphia’s Elfreth’s Alley. It was dedicated in 1702, shortly after this period of complete anarchy and served  as a route to connect local merchants’ property with the already thriving Second Street. As the society dedicated to the alley’s preservation writes: Elfreth’s Alley — popularly known as “Our nation’s oldest residential street” – dates back to the first days of the eighteenth century. Twenty years after William Penn founded Pennsylvania and established Philadelphia as its capital, the town had grown into a thriving, prosperous mercantile center on the banks of the Delaware River. Philadelphians […]
