Public transit is often portrayed as a low-cost, energy-efficient alternative to auto driving. Cato Institute Senior Fellow Randal O'Toole debunks that portrayal in an Issue Analysis for the Georgia Public Policy Foundation.

"In fact, transit is much more costly than driving, and requires huge subsidies to attract any riders at all," writes O'Toole in, "Public Transit in Georgia: High Costs for Low Fares," which was released last week by the Foundation.

"Moreover, transit systems in the vast majority of American cities use more energy and emit more greenhouse gases than the average car," adds O'Toole, whose latest book is, "Gridlock: Why We're Stuck in Traffic and What to Do About It."

For every dollar collected in fares from transit riders, the average transit system in America requires more than $2 from taxpayers for operating subsidies plus more than $1 for capital improvements and maintenance, according to O'Toole's analysis.

While it's no surprise that Georgia's transit systems require large subsidies, it may surprise Georgians to know that most systems are "far less environmentally friendly than a typical sports utility vehicle," O'Toole writes.

He compared the cost of driving with the cost of transit and found that the total cost of driving in Georgia is still less than 22 cents per passenger mile, with a subsidy per passenger mile of a half-cent. By comparison, the national average cost of public transit is more than 90 cents a passenger mile, more than 70 cents of which is subsidized by non-transit users.

In Georgia, the costs are a little lower: 84 cents per passenger mile, 72 cents of which is subsidized. Georgia transit riders pay an average of 85 cents every time they board a bus, while taxpayers pay an average of nearly $3 to support that trip.

As for energy efficiency, O'Toole says, driving is more energy efficient and cleaner than most public transit in Georgia. The most energy efficient transit systems in Georgia are vanpools, the closest thing public transit offers to actual cars.

Why is transit less energy efficient? One reason is that a crucial part of energy efficiency is filling the seats, O'Toole says. The average transit bus in Georgia fills only 22 percent of its seats, and counting standing room they operate an average of about one-sixth full. The Atlanta rail system fills an average of 39 percent of its seats, but counting its ample standing-room capacity it operates only about one-eighth full.

Those who want to save energy and reduce pollution would do better encouraging people to drive more fuel-efficient cars than encouraging cities to expand transit service, O'Toole says.

That's not to say there are no ways to make transit a better deal. For example, O'Toole cites the mantra of rail proponents - "Highways are subsidized, so we need to subsidize rail transit as well" - in calling for an end to highway subsidies. That's one way to get transit authorities to be more cost-conscious instead of justifying the diversion of billions of dollars to rail projects. Contracting out, privatizing and downsizing transit vehicles also can contribute to lower costs and more efficient public transportation, he says.

For those who truly have no access to automobiles or are unable to drive, O'Toole suggests vouchers. From taxis to airlines, a voucher enables those individuals to make the best choice for their needs - at a lower cost to taxpayers.

O'Toole's Issue Analysis should become a cautionary tale for Georgia's planners chomping at the bit for their turn at the federal trough. And it should be a road map for local governments now that Gov. Sonny Perdue has signed into law the Transportation Investment Act of 2010, which would allow regions to come together on projects to be funded by a penny sales tax. For transportation policy to succeed, it is imperative that Georgians see prudent expenditures that relieve congestion relief and improve mobility.

Well, I'm glad you can just pop into your shiny green SUV and take off with you air conditioner on and your stereo blaring in my face as you jabber on your expensive I-phone at a light. You see,some of us don't have that option! Many of us are maybe low-income,disabled, or elderly! We're not all homeless,criminal,etc.like you might think, but we have to put up with folks who put down the only options we have to get around to get to work,etc.! A system like that in Charlotte, NC is what we could use (and one that works better than MARTA) and an attitude that helps,not hurts,those with lesser means than you have. ASny bus or train system that advertises cars inside or on it will fail too because it reminds riders what they don't have.

You're being misleading with your headline and when you say that transit systems are "far less environmentally friendly than a typical sports utility vehicle." It's true that buses are often less environmentally friendly than cars since they do not always run at capacity. But O'Toole's report concedes that heavy rail is much more environmentally friendly than cars.

Of course there are far more reasons to support transit than its environmental friendliness. It is far more effective than anything O'Toole prescribes at reducing traffic congestion. It helps create dense urban centers that are the engines of our economy. And it is much safer than driving.

Though the likes of O'Toole may not believe it, transit is a valuable part of any city's transportation mix.

@ Benita Dodd: Your comment makes absolutely no sense. We are not talking about actual vs. potential cost of gasoline or actual vs potential cost of transit. We are talking about equally comparing the energy efficiency (and emmissions) of an automobile and a transit vehicle, ceteris paribus, and making a conclusion about the future using incorrect data.

In addition to this methodology error, Mr. O'Toole's analysis (which I read completely) gave no weight to a wide variety of other factors, including but not at all limited to total capital costs for ALL road construction, ongoing rebuilding, and maintenance...to actual ownership costs of a private vehicle. (Tolls would add only a few pennies per miles? Unlikely. Ask GA 400 drivers. Putting "tolls or other usage fees" on all roads instead of subsidies? That won't sell at all.)

In short, for such sweeping conclusions, his report was far too short and simply not rigorous enough to prevent challenge.

Mr. O'Toole is as very vocal libertarian, a political philosophy I support quite often, particularly when government waste and foolishness are in view. But as an author of opinion books and provider of "consulting services" Mr. O'Toole wants to sell, his objectivity is open for discussion.

As a statistician, I remain committed to the belief that valid conclusions can only come from valid methodology. And proper methodology can only come from complete objectivity.

Mr. O'Toole's analysis is lacking in both.

So, statistician, let's give rail potential for what it might do as opposed to what actually occurs? The next time you go to the gas station, perhaps they should charge you based on the capacity of your tank as opposed to what you actually put in there.

RE: "a penny sales tax"

I really appreciate the common sense light of reality that this article shines on the "Lite Rail" farse that some folks here in Cobb county have dreams of tying this county down with. That said, I have to point out that there is no "penny sales tax". It is a 1% sales tax...which means you are paying more than a penny anytime you spend more than a dollar. People are clueless enough already...lets stop acting like "it's only a penny" when it is not.

Mr. O'Toole's analysis of existing transit systems -- as reported by Ms. Dodd -- is totally vacuous, and is statistically invalid, trumpeting stacks of figures without proper comparison or discussion of methodology. Furthermore, to make the conclusion that transit systems are less energy efficient in general than private automobiles using a per actual passenger carried denominator is a specious argument at best.

Make your point using valid comparisons, Mr. O'Toole. Base it on capacity -- per available seat/space, not per used seat.

The assumption made is all private vehicles are operating at a 100% load factor, when in fact the average 5-passenger car is running at a 20% load factor. So cars are more efficient and “greener” than transit because transit load factors are low ??? Sorry. Not valid. If existing rail transit operated at 100% capacity, the costs per passenger mile cited by Mr. O'Toole would be less than 1/4 of the numbers reported, making the conclusions of the analysis fully misleading.

Ms. Dodd seems to think transit planners are in their business only to get a shot at "the federal trough". To the contrary, entirely Ms. Dodd. Those who are truly interested in bringing economic and efficient transit to Georgia and the Country as a whole are designing their systems and structures to operate WITHOUT subsidy. But politicians don't like that -- because they can't control a transit system that doesn't need government cash. Just ask the good folks at AMT and OTG. They have the answers. Poorly designed and managed systems using old transit models built as political solutions are NOT examples of good transit solutions and are NOT valid for comparison due to their low usage factors.

This looks like a hit job on transit done by the road building lobby. But that has never happened around here, now, has it....

Most people commenting on Cobb's lack of rail were not here when we voted on MARTA. It was rejected because MARTA was to supply one line into Cobb, which stopped at Windy Hill Rd. Cobb taxpayers were to pay for that line over 25 years before we ever received it.

Rail should follow the interstates and land for parking should have been purchased many years ago.

Well written! The key is ridership. The key to ridership is service points... the old "take people from where they are to where they want to be."

If construction costs are reduced, more miles can be constructed. More miles can reach more service points. It's all very much interconnected.

This is why I like the OTG HighRoad system's approach. More detail at www.OTG-Inc.com .
