...nearly 10% for both the bus and the rail.

As Paul Krugman noted, a big percentage increase in a tiny number still leaves you with a tiny number.  The vast majority of US commuters still get to work by driving a car in which they are the only passenger.

This shows what could be accomplished with a high gasoline tax that would be used to build public transit.  While, as Dave notes, this is merely a large increase in a very small percentage of people, the percentage of drivers leaving private motor vehicles for public transit would increase by a huge amount if gasoline were taxed at a reasonable level, say an additional $4/gallon.

I have been pushing the mass transit button for years and I do hope that it catches on,to the exclusion of private automobiles.The problem is the tens of thousands of little towns like where I live(15,000)and the town across the river is about the same size.We have no mass transit,so to speak.We have two or three "cab" companies that are mom and pop kinda things,no buses except for the old folks storage houses and no trains of course.We do have a shot load of cars and trucks though.Multiply our town by the tens of thousands of others and I believe that we sure aren't helping the environment.Oh and don't forget the thousands of lawn mowers that we have belching out pollutants.We seem to be like so many other places,in love with our cars.Gotta find an alternative that small towns can use.

Small towns should be easily bikeable.  But there's also no reason that public transit wouldn't work there, so long as people actually use it and give up their cars.

...Used to be a time, right after the turn of the century in the 1910s and even 20s, when almost every sizable town, even those with just a few thousand, would have streetcars that went up down all the major streets.
