I do not think there is profitable mass transit system in the US. They are heavily subsized. They still should be invested in because if you consider the larger picture the often times do pay for themselves. The car is heavily subsidized (i.e. roads and development patterns). One thing that motivates people to use mass transit more is if it becomes more convenient than driving and/or it cost significantly less. So if we keep fixing the congestion problems on the roadway with widening roads (which never have the results we want,

AsWalter Kulash, a well known traffic engineer, says, "Trying to solve the problem of traffic congestion by adding lanes is like trying to solve the problem of obesity by loosening your belt."
then we are just enabling everyone's driving habits. The way we build our cities also continues to add to this problem. Luckily, this is beginning to shift to the side of reason as mixed-use is becoming the norm. Frankly, I think people are finally sick out it. We discussed at the meeting last week, how much time living near work saves everyone. This time can be reinvested into our families, health, jobs or whatever floats your boat.
I have thought a subway would be great. Digging up West End and Hillsboro Rd to name a few, but I do not think it would be a better option than a light rail system. It is too invasive. I can not help to think of the trams in Amsterdam. These seemed to work extremely well, right along side with the pedestrian, cars, and bicycles.
I am surprised no one has mentioned bikes and walking. Most of the surrounding neighborhoods to the CBD are within 10-15 minutes by bike and obviously less time to destinations within the neighborhoods. Walking seems to be more viable within the neighborhood. This is easier said than done because we convince ourselves we do not have time for it. I am just a guilty as the next. Though I do try occasionally and I am always the better for it.
