Because Exclusive Bus Lanes Aren’t Expensive Enough

Los Angeles transit officials are eagerly contemplating the opportunity to spend money converting the Orange bus-rapid transit line into a light-rail line. To promote this idea, they are letting people know that light rail will be faster, more comfortable, and operate more frequently (so riders will be less likely to have to stand) than buses.


These lanes are exclusively dedicated to buses, but transit agency officials say they need to replace them with light rail because there is no room to run more than one bus every eight minutes.

Of course, all of these things are wrong. The current bus line averages 26 mph, about 4 mph faster than the average light-rail line. Buses can be just as comfortable as light rail, and when vehicles are full, a higher percentage of bus riders get to sit down (about two-thirds as opposed to less than half). As for frequencies, the current schedule of the Orange line calls for one bus every eight minutes at rush hour. Since the road is closed to all other traffic, somehow I think they could squeeze a few more in if they wanted to.

Transit and Congestion

The Antiplanner was apparently exposed to a bad cold when traveling last week and didn’t feel up to writing a timely post for this morning. (Would I have avoided this if I had a driverless car to take me to San Francisco instead flying?)

However, someone emailed me in response to yesterday’s post asking if I was guilty of hyperbole when I said that, outside of New York, transit doesn’t “carry enough people to relieve much congestion.” So I prepared the above chart showing transit’s share of total travel (not just commuting) by urbanized areas. Only urbanized areas in which transit carries more than 2 percent of travel are shown.

Who Needs Transit, Anyway?

Rail advocates often call the Antiplanner “anti-transit,” probably because it is easier to call people names than to answer rational arguments. I’ve always responded that I’m just against wasteful transit. But looking at the finances and ridership of transit systems around the country, it’s hard not to conclude that all government transit is wasteful transit.

Nationally, after adjusting for inflation, the APTA transit fact book shows that annual taxpayer subsidies to transit operations have grown from $1.6 billion in 1970 to $24.0 billion in 2012, yet per capita ridership among America’s urban residents has declined from 49 to 44 trips per year. A lot of that money ends up going to unionized transit workers, but the scary thing is that these workers have some of the best pension and health care plans in the world that are mostly unfunded–which means that transit subsidies will have to increase in the future even if no one rides it at all.

Capital and maintenance subsidies are nearly as great as operating subsidies, largely due to the industry’s fascination with costly rail transit. In 2012, while taxpayers spent $24 billion subsidizing transit operations, they also spent nearly $10 billion on maintenance, and more than $7 billion on capital improvements. In 2012, 25 percent of operating subsidies went to rail transit, but 56 percent of maintenance and 90 percent of capital improvements were spent on rails.

Slower Than Molasses in a Minnesota Winter

Remember the Twin Cities light-rail line that was supposed to average 17 mph but, after testing, was scheduled for just 13-3/4 mph? It turns out that, in actual operation, it averages less than 12.5 mph. That means it takes 53 minutes to go from downtown Minneapolis to downtown St. Paul, 36 percent longer than the 39 minutes originally promised and more than twice as long as the 26 minutes required by a bus.

What’s slowing the trains down? Traffic signals. Apparently, the city of St. Paul is reluctant to give the trains signal priority over all other traffic. “It is hard to rationalize a train with 300 people stopping at an intersection with no cross traffic,” says Metro Transit’s general manager. But it is also hard to rationalize giving the few people who ride the train priority over the thousands of people who use other modes of travel.

Portland or Portlandia?

As most Antiplanner readers know, Portlandia is a television comedy dedicated to making fun of the weird things that happen in Portland. The only problem is that (as actress Carrie Brownstone noted), “no matter how far out on a limb we went, we always ran into that person [in Portland] within two days.”

Such is the recent plan to rely on bicycles to rescue the city in the event of an earthquake or other natural disaster. “One of the bright, shining spots for Portland in a disaster like an earthquake is that we’re still going to get around,” a Portland disaster specialist told the Oregonian. “When roads are broken, when fuel supplies are cut, those kinds of things, you can bet that our city will still get around.”

On one hand, even the biggest cargo bikes will not be able to move the fire and rescue equipment needed to truly handle a natural disaster. On the other hand, even the worst earthquakes in modern times in the U.S. did not seriously impede the ability of motor vehicles to participate in rescue and recovery.

Planning for the Unpredictable

How do you plan for the unpredictable? That’s the question facing the more than 400 metropolitan planning organizations (MPOs) that have been tasked by Congress to write 20-year transportation plans for their regions. Self-driving cars will be on the market in the next ten years, are likely to become a dominant form of travel in twenty years, and most people think they will have huge but often unknowable transformative effects on our cities and urban areas. Yet not a single regional transportation plan has tried to account for, and few have even mentioned the possibility of, self-driving cars.

Instead, many of those plans propose obsolete technologies such as streetcars, light rail, and subways. These technologies made sense when they were invented a hundred or so years ago, but today they are just a waste of money. One reason why planners look to the past for solutions is that they can’t accurately foresee the future. So they pretend that, by building ancient modes of transportation, they will have the same effects on cities that they had when they were first introduced.

If the future is unpredictabie, self-driving cars make it doubly or quadruply so.

  • How long will it take before self-driving cars dominate the roads?
  • Will people who own self-driving cars change their residential locations because they won’t mind traveling twice as far to work?
  • Will employment centers move so they can take advantage of self-driving trucks and increased employee mobility?
  • Will car sharing reduce the demand for parking?
  • Will carpooling reduce VMT or will the increased number of people who can “drive” self-driving cars increase VMT?
  • Will people use their cars as “robotic assistants,” going out with zero occupants to pick up groceries, drop off laundry, or doing other tasks that don’t require lots of supervision?
  • Will self-driving cars reduce the need for more roads because they increase road capacities, or will the increase in driving offset this benefit?
  • Will self-driving cars provide the mythical “first and last miles” needed by transit riders, or will they completely replace urban transit?

Wait Six Years to Buy Your Next Car

You’ll be able to buy a car that can drive itself under most conditions, with an option for override by a human driver, in 2020, according to the median estimate in a survey of 217 attendees of the 2014 Automated Vehicles Symposium. By 2030, the group estimated, you’ll be able to buy a car that is so fully automated it won’t even have the option for a human driver.

Though 2020 is just six years away, there remains a lot of debate over how the industry is going to get there. Most auto manufacturers are incrementalists, adding automated features such as adaptive cruise control, self-parking, and traffic-jam assist, two or three at a time. Google and some others in Silicon Valley, however, are more interested in producing highly or even fully automated cars as soon as possible.

Autonomous Cars Yes, V2I No!

Yesterday, President Obama gave a speech in Virginia calling for mandatory installation of vehicle-to-vehicle and vehicle-to-infrastructure communications in all cars. By coincidence, the Association for Unmanned Vehicle Systems International (AUVSI) is holding its annual symposium on autonomous (that is, driverless) cars in California.

V2V allows vehicles to communicate with one another to allow them to avoid accidents, while V2I allows highway infrastructure (such as traffic signals) to communicate directly with motor vehicles. While Obama touts the safety benefits of these technologies, there are at least four reasons why they should not be mandatory.

First, V2V and V2I communications pose serious security risks for travelers and cities. With V2V communications, an automobile that suffers a fender-bender would communicate to all nearby vehicles that they ought to take a different route to avoid congestion.

San Antonio Petition May Stop Streetcar

San Antonio streetcar opponents submitted a petition today to allow voters to decide whether the region’s transit agency, VIA, should spend $280 million on a 5.9-mile streetcar. They needed about 20,000 signatures, and submitted well over 26,000 of which they personally pre-verified nearly 24,000.

Unfortunately, this petition still has several hurdles to leap. First, the city is claiming that signature gatherers didn’t follow proper procedures; the petitioners claim they did, and that the procedures the city wants them to follow only apply to recall petitions. Second, even if the measure makes it to the ballot and is approved by voters, VIA argues that it won’t be bound by the results.

Bus Shelters for the Poor, Trains for the Rich

Low-income residents of the Twin Cities can rest easy, as planners at the Metropolitan Council, the area’s regional planning agency, are proposing a regional transit equity plan. According to the Metropolitan Council’s press release, this equity plan consists of:

  1. Building 75 bus shelters and rebuilding 75 existing shelters “in areas of racially concentrated poverty”; and
  2. “Strengthen[ing] the transit service framework serving racially concentrated areas of poverty” by building bus-rapid transit and light-rail lines to the region’s wealthy suburbs.


The blue line, the yellow line to St. Cloud, and the green line between the Minneapolis interchange and St. Paul Union Depot are open; the next priority is the green line from the interchange and Eden Prairie.

Bus shelters for the poor, light rail for the rich: that sounds equitable! Of course, the poor will be allowed to ride those light-rail trains (for example, if they travel to the suburbs to work as servants), just as the well-to-do will be allowed to use the bus shelters. But for the most part, the light rail is for the middle class.
