With gas over $4 a gallon, many people have been adjusting to the impact on their budgets.
I've been amazed how many additional riders I've seen waiting for buses. We live within six blocks of a hub where three buses stop. Unfortunately, none of those buses go near my workplace. In the past (around a year ago) I might see three or four people waiting at the main stop. Now, I'll see people waiting at stops along the route(s). I myself rode the bus to a major sporting event I was attending for work. I was amazed at the number of people riding. Yes, it took me two hours round trip to get there (one way) - but to me, it was worth it. I walked past the cars idling, waiting to get into the parking lot and smiled to myself.
Not two or three years ago, I remember seeing the buses drive by at night. Sometimes they looked completely empty.
Infrastructure and public transportation are a worthwhile investment for a community. The libertarians disagree with this, but I believe they are worth spending money on. I believe they are worth raising taxes for. In my community, the suggestion of raising taxes for anything is the kiss of death for a politician. But at what point will we realize that the investment will pay for itself in the long run. The roads here are in bad shape. So many people have fled to the suburbs, and the road systems haven't grown along with them. So traffic (from the suburbs into the city during the morning rush hour) is abysmal. The state government has approved million dollar roadway expansion projects, but can't find the consensus to build public transportation at the same time.
I've lived in communities where there is a strong public transportation system. Not only is it affordable, it runs late into the night. It's safe and reliable. That investment originally cost those communities a great deal, but the quality of living there is high.
