Ran across this on Copenhagenize.com:
This person in Brisbane charted out the time/costs/etc. for traveling to work via bus, and via bicycle for one week respectively. Would love to see a similar chart by people in Dallas, including traveling by car. For me personally, I know the cost in gas+parking downtown+amortized monthly car payment is more than a daily two-way local bus/light-rail pass. It would also be interesting to see calories burned by each method.
