Are We Approaching Peak Transit?

“Billions spent, but fewer people are using public transportation,” declares the Los Angeles Times. The headline might have been more accurate if it read, “Billions spent, so therefore fewer are using public transit,” as the billions were spent on the wrong things.

The L.A. Times article focuses on Los Angeles’ Metropolitan Transportation Authority (Metro), though the same story could be written for many other cities. In Los Angeles, ridership peaked in 1985, fell to 1995, then grew again, and now is falling again. Unmentioned in the story, 1985 is just before Los Angeles transit shifted emphasis from providing low-cost bus service to building expensive rail lines, while 1995 is just before an NAACP lawsuit led to a court order to restore bus service lost since 1985 for ten years.

The situation is actually worse than the numbers shown in the article, which are “unlinked trips.” If you take a bus, then transfer to another bus or train, you’ve taken two unlinked trips. Before building rail, more people could get to their destinations in one bus trip; after building rail, many bus lines were rerouted to funnel people to the rail lines. According to California transit expert Tom Rubin, survey data indicate that there were an average of 1.66 unlinked trips per trip in 1985, while today the average is closer to 2.20. That means today’s unlinked trip numbers must be reduced by nearly 25 percent to fairly compare them with 1985 numbers.

Building a Self-Driving Car in Your Garage

You can build a self-driving car in your garage–if you are a computer genius. George Hotz, a 26-year-old computer whiz who was the first person to unlock the iPhone when he was just 17 and later reverse engineered a PlayStation, has built a self-driving car. Though it has cost him about $50,000, most of which went for the car itself, his real goal is to design a hardware/software system that will turn any recent car into a self-driving car for very little money.

As described in the video above, rather than write a computer program with a zillion rules for driving, his method has been to teach his car how to drive by using other drivers as examples. Most self-driving cars use millions of lines of code; his uses just 2,000. Continue reading

How Do You Define “Feasible”?

States and regions all over the country are developing plans for high-speed or conventional-speed intercity passenger trains. One of the first steps in writing such plans is the “feasibility study.” But the people writing these studies have a curious definition of “feasible.”

Louisiana Governor John Edwards doesn’t even understand the definition of “light rail.” He asked Secretary of Transportation Anthony Foxx yesterday for federal funding for light rail between New Orleans and Baton Rouge. Or maybe he asked for money for commuter rail; it’s hard to know from the media reports. But Edwards is on the record saying he will do everything he can “to make sure that as soon as possible we can pursue light rail” between the two cities, which are about 80 miles apart on Interstate 10.

Washington Metro Surrenders

New York City was harder hit by snowstorm Jonas than Washington, getting 27 inches of snow compared with 18 or 19 inches in Washington. Yet New York’s subways kept running and commuter trains and buses operated for as long as they could, while Washington Metro shut down its system before the storm got serious.


This is what it takes to shut down Metro subways. Flickr photo taken Sunday morning after the storm by Ted Eyten.

Sunday morning, New York sprang back to life while Washington remained shut down. By this morning, the vast majority of the New York system, including most commuter-rail lines, almost the entire subway system, and some buses will be operating. Washington, meanwhile, will operate the subway portions of its rail lines and just 22 out of 325 bus lines.

The Good-Weather Transportation System

Weather forecasters predict that Washington, DC will get as much as two feet of snow tonight through Sunday morning. Fortunately, Washington has Metrorail, an “all-weather” transportation system.


Some buses might get stuck, so we’ll shut the whole system down. Photo taken during 2009 snowstorm by Mr.TinDC.

Big Brother Wants to Run Your Self-Driving Car

As a part of his 2017 budget proposal, Secretary of Transportation Anthony Foxx proposes to spend $4 billion on self-driving vehicle technology. This proposal comes late to the game, as private companies and university researchers have already developed that technology without government help. Moreover, the technology Foxx proposes is both unnecessary and intrusive of people’s privacy.

In 2009, President Obama said he wanted to be remembered for promoting a new transportation network the way President Eisenhower was remembered for the Interstate Highway System. Unfortunately, Obama chose high-speed rail, a 50-year-old technology that has only been successful in places where most travel was by low-speed trains. In contrast with interstate highways, which cost taxpayers nothing (because they were paid for out of gas taxes and other user fees) and carry 20 percent of all passenger and freight travel in the country, high-speed rail would have cost taxpayers close to a trillion dollars and carry no more than 1 percent of passengers and virtually no freight.

The Obama administration has also promoted a 120-year-old technology, streetcars, as some sort of panacea for urban transportation. When first developed in the 1880s, streetcars averaged 8 miles per hour. Between 1910 and 1966, all but six American cities replaced streetcars with buses that were faster, cost half as much to operate, and cost almost nothing to start up on new routes. Streetcars funded by the Obama administration average 7.3 miles an hour (see p. 40), cost twice as much to operate as buses, and typically cost $50 million per mile to start up.

Time to Reconsider

Portland’s first light-rail line turns 30 years old this year, which is about the expected lifespan of a rail line. Not by coincidence, the system was highly unreliable last year, being “plagued with delays and disruptions” and having terrible on-time performance.

The line between Portland and Gresham originally cost more than $200 million to build, which in today’s dollars is around twice that. It is likely it will cost roughly that amount of money to restore it to like-new condition.

But Portland has a choice. Instead of sinking a bunch of money into an already-obsolete transit system, it could scrap it and replace it with buses. Before building the rail line, the parallel freeway had HOV lanes; restoring those lanes (or turning them to HOT lanes) would give the buses an uncontested route to fallow. We know that the buses would be faster than the rail, because the rail line was slower than the buses it replaced.

A Quarter Trillion for the Northeast Corridor

A recent draft environmental impact statement published by the Federal Railroad Administration estimates that it would well over a quarter trillion dollars in capital improvements to make Amtrak “a dominant mode for Intercity travelers and commuters” in the Boston-Washington corridor. Even that is optimistic as the data in the report suggest that Amtrak would be far from dominant even after spending that much money.

Click image to go to the download page for the draft environmental impact statement, which is downloadable in more than 30 parts totaling well over 30 megabytes.

The statement considers four alternatives:

  • No action would keep train service at current levels. This would nevertheless cost $19.9 billion in maintenance and improvements over the next 25 years.
  • Alternative 1 would increase service at a rate equal to the region’s population growth. This would cost around $65 billion (the average of a range given in the DEIS), or $45 billion more than No Action.
  • Alternative 2 would increase service faster than population growth at a cost of around $133.5 billion, or more than double Alternative 1.
  • Alternative 3 would supposedly make rail “a dominant mode” in the region at a cost of around $287.3 billion, more than double Alternative 2.

CES & Self-Driving Cars

The Consumer Electronics Show opens in Las Vegas today, so the next few days are likely to see new hype (some say overhype) about self-driving cars. Last month, Yahoo reported that Ford and Google would announce that they would build self-driving cars together, but Ford’s announcement yesterday about its electronics plans didn’t mention Google. Ford may still make an announcement with Google later in the show, but it is curious that Yahoo’s original story doesn’t seem to be live anymore.

A combination that has been confirmed is between General Motors and Lyft. While their goal is to create a system of shared, self-driving vehicles, the only substance in the announcement was that General Motors was “investing” $500 million in Lyft. So it isn’t clear which, if either, company will be developing the software and hardware needed to make GM cars self-driving.

A Ford-Google partnership probably makes more sense than a GM-Lyft combine. With the former, Ford offers car-making expertise while Google offers the software and the resulting products could be used for car sharing, individual ownership, trucking, and other services. The GM-Lyft partnership is limited to just sharing and neither of the partners has the software to do true autonomous cars.

What Is Your Sin?

Over at Green Car Reports, the “guide to cleaner, greener driving,” electric car advocate David Noland asks, “Which sins worse: cars or planes?” The “sin,” of course, is carbon emissions, and his answer, while interesting, is flawed in many respects.

“The passenger jet blows away the automobile in terms of efficiency and CO2 emissions per mile,” he says, a result he apparently considers surprising. But it’s not surprising at all to anyone familiar with the Department of Energy’s Transportation Energy Data Book. According to tables in the book, airlines emitted about 2,568 grams of carbon per passenger mile in 2013, while the average car emitted 3,144 grams (or 3,564 if SUVs and other light trucks are included).

But it’s not enough to show that both cars and airlines have been rapidly improving their energy efficiency. Noland wants to really blow cars out of contention, so he biases his analysis in several ways.
