Okay.
If the population of a town is 10 and they drive a total of 1,000 miles, then the per capita milage is 100. Two years later the per capita milage has fallen 10% to 90 but on counting the inhabitants we find the population has risen 10% to 11. Under this scenario the total milage must have been 990 which represents a drop of only 1%. If the population had doubled, a 10% drop in per capita milage would mean they had driven a total milage of 1,800 or an 80% increase.

Returning to your example: If per capita driving were unchanged and the population doubled, then total miles would be 2,000, or a 100% increase. Not 1,800 as in your scenario. Clearly, 1,800 is a smaller number than 2,000 amd therefore represents a "real" drop in miles driven.

Evidently the schools don't do a better job of teaching statistics in Ireland than they do here. Look at it this way. A per capita drop in mileage and a drop in total mileage are two different statistics, and they mean different things. But they both can indicate a "real" drop in miles driven.

It isn't about whose schools are better than whose but a mistaken belief that rising population, increases the significance of falling per capita figures, when if anything it has the opposite effect. This was the point of my original post which you might care to go back and read.

"Peak car" is still a pretty interesting concept and there's lots to read on the concept if you don't mind wading through Google results.
This Treehuggerarticle summarizes from a number of sources .
(Note: Peak Grammar may be a real phenomenon too... )
This Treehuggerarticle summarizes from a number of sources .
Newman and Kenworth also point to a Brookings report (2008) that indicated that car use (vehicle miles traveled) plateaued in around the 2004 - 2006 timeframe, and since 2007 has begun to subside. Another set of researchers found a similar pattern in Australia, with the peak of car use also occurring at around that same time, and declining after. Phil Goodwin, a transport economist in the UK, has put together a similar set of findings.
Newman and Kenworth then site data from the Millenium Cities Database (though not updated since 2005) to shore up their idea of peak car use by showing that strong growth rates have reversed: growth in per capita car use globally was 42% in the 1960s, 26% in the 70s and 23% in the 80s. By the last period observed - 1995 to 2005 - growth had dropped to a 5% increase. Five percent growth is still growth, however, so Newman and Kenworth show that vehicle kilometers traveled (vkt) per capita have declined in quite a few European cities as well as a few famous car-friendly U.S. cities - Altlanta's vkt per capita dropped 10.1 %, Houston's vkt went down 15.2%, while Los Angeles' vkt dropped 2%. Since more recent data isn't ready, the picture and solidity of the peak car use theory could still change. In the U.S., for example, driving rates rose in 2010 by 0.7%.

One thing that seriously needs to be considered is having bus and train companies as for-profit agencies and not governmental. I think if there was a profit to be made it would help get more busses out there, more train systems out there. Anyone know how Amtrak and Greyhound are doing these days? I know here in NL that Arriva and NS is making good profit and expanding, but I'm not familiar with US companies anymore.

Statistics are statistics, but aren't we fooling ourselves when we think there's going to be a major switchover in North America from the Car culture to a mass transit/bicycling culture? I think a few people will make the change, but automobiles are so ingrained into our society's psyche and our lifestyle as a whole that I believe only something major that would rip automobiles out of the hands of the car addicts would make any real difference. Something like a sudden complete unavailability of gasoline. For many of us, that are bicycle commuters, it's nothing to ride the miles to work - but if a person has not ridden for years or at all, that first couple of miles after a "I'm going to commute by bicycle!!" decision are very, very hard and I bet not that many would continue. I'm facing it - as a bicycle commuter I am different from the mainstream. My example may make a few others try it, and perhaps successfully, but if we're hoping for a major North American transition away from the car culture we're fooling ourselves. I like the 1.7% figure, but I don't believe the culture will change.

I work at Greyhound and it is doing fine after a couple of tough years. Buses are full.

Wages are going down while the cost of gasoline and insurance is going up.
I think that, in the future, we will see much more in the way of "one car" families instead of "two car", or "two car" families instead of "three car".

I believe we are going to see a trend towards more "infill" development in most North American cities and in some places the density of the population coupled with the cost of parking a car, will force many to forego the ownership of a car.

This doesn't mean you cannot start your own private bus line. However, you will probably not get the most lucurative routes (if you can call them that!) and will have to run empty buses until people get used to using your service. Furthermore, if the city does not subsidize your company, it will be highly unlikely you'll be able to make a profit.

Clearly, 1,800 is larger than 1,000 which was the figure for total miles driven two years previously in my example.
It isn't about whose schools are better than whose but a mistaken belief that rising population, increases the significance of falling per capita figures, when if anything it has the opposite effect. This was the point of my original post which you might care to go back and read.

Well, the number of miles driven won't go down until people individually start driving less--in other words, when the per capita numbers go down. We can't do much about how many individuals choose to live in a given location. But we can each drive less as individuals, and we can help our own communities to develop in ways where cars are less necessary for everyday travel. I think most people on this forum would like to see that, and (if they would ever stop to think with an open mind) most people in the world would like to see peak car become a reality.

In 1900, nobody (literally) would have predicted an end to the dominance of horses and trains in transportation. Three years later, Ford and Olds had sudden inspirations to mass produce cars. Within 25 years--only one generation--the automobile was the dominant mode of transportation in the United States. Other developed countries weren't too far behind.

This idea to have for-profit bus and rail service has been discussed for years but it never happens. Here's why you don't see private companies start bus and rail service. First, almost all private bus lines that are in existance do not make a profit! The fare box only pays for the driver's salary and some of the gas but that's all. The money you pay per ride will cover anywhere from 20 - 60% of the average cost of the service. Cities and states then pay for the maintenance, bus depot and other administrative cost a private bus company incures in providing service. When it's time to buy new buses, cities will help finance the loans bus companies have to make while allowing them to increase fares to pay back the money.
This doesn't mean you cannot start your own private bus line. However, you will probably not get the most lucurative routes (if you can call them that!) and will have to run empty buses until people get used to using your service. Furthermore, if the city does not subsidize your company, it will be highly unlikely you'll be able to make a profit.

In return for the low-cost buses, the bus lines agree to serve smaller communities across the state. Greyhound seems to be opting out of this subsidy more and more. It looks like the Dog is trying to focus on major inter-regional runs and the big cross-country routes. They seem to be leaving more of the feeder routes to smaller companies.

who's to say how long it will take for some other transportation mode to gain dominance over the automobile? Major changes almost always unfold very swiftly once they get started.
In 1900, nobody (literally) would have predicted an end to the dominance of horses and trains in transportation. Three years later, Ford and Olds had sudden inspirations to mass produce cars. Within 25 years--only one generation--the automobile was the dominant mode of transportation in the United States. Other developed countries weren't too far behind.

I imagine the same was said of horses in 1900. They were romantic, exciting, a symbol of freedom and sexiness. Bicycles also, for that matter. As is often said in marketing, peoples' desires never change--just the objects that they desire.

Unfortunately, just as we are starting to pull back from carmania countries like China and India are becoming much more car dependent. I don't know much about India but owning a car is VERY expensive in cities like Shanghai, the taxes are as expensive as the car itself..but businesspeople still do it because they have to. Traffic is as bad or often worse than here.
I think politicians are attacking bicycling now because car ownership and the percentage of people with driver licenses is falling. Huge, huge numbers of unsold cars are sitting on the docks, losing value by the day. The unsold new cars in Long Beach stretch a very long distance. And that is just Toyotas.
The US is now I think 16th in car ownership. Luxembourg is first, Italy is second..
Many people would like to have a car but they are living on savings or their increasingly low wage mcjobs don't pay enough to own one. Teenagers socialize on the net or on their cell phones and dont feel as compelled to drive as they used to. Of course, when autonomous driving is decided on everyone will have to buy a new car at least once, if they want to use highways or drive in the city. But once is not enough to revive the kind of sales they used to have.
More people riding bikes must seem to politicians as a visible reminder that our standard of living is changing. Rather than see the fact that Americans are adaptive, they want to punish us. "kill the messenger", so to speak.

Google "National City Lines" - its one of the most important untold stories of the 20th century.
To unseat automobiles from their lofty position would be more difficult than the situation in 1900. Cars are not just transportation, they are status symbols and addictive adult toys. When my daughters were teenagers, one of their first questions when some guy wanted to date them was "Does he have a car?" and "What kind of car?"
