"But if more commuters took public transit, that would free up our existings roads for use by transport. Building more roads just convinces more people that driving is the way to go, so they buy second cars and eschew transit. Soon those roads fill up, and we're right back where we started -- minus a few hundred million dollars, of course."
I agree completely with the above comment...to me when I hear people talk about a balanced approach to transportation, I think it's a joke...there hasn't been a balanced approach to transportation in almost any city in N. America, save of course maybe NYC, which actually has an extensive true 'alternative' to driving, which means giving people 'real' choice...
And b/c there hasn't been a balanced approach for most of us, I think it's time that transit gets a chance to 'catch up!'
And when are we going to realize that doing things that support sprawl (i.e. building more highways) is only furthering the problem of sprawl.
Sprawl is bad...simple enough idea, right...then instead of building more highways to accomodate the current sprawl and/or future sprawl, lets instead RE-design the current sprawl to make it more compact and do NOTHING to encourage new sprawl...in other words, lets not do more to cause more problems down the road...I mean, are we learning here or what!
All of this means to me that we have to HEAVILY invest in REDESIGNING our cities FIRST...designing them to support a backbone of subways, and dedicated intra-urban trains/transitways...
Otherwise, were only continuing with half measures...and that means we still 'don't get it'!!
So, no more roads, RE-design and HEAVY transit funding (and by the way, investing in transit doesn't mean giving all the money to GO again to support suburbanization in another form, but rather to invest in inner city development...
