Create a "fuel-shed" map
This could either be an interactive app or just a map/infographic that shows the "fuel-shed" or "commute-shed" of the areas surrounding Chattanooga (playing off the idea of a watershed). The idea is that it would show concentric rings surrounding downtown to illustrate how much $$/month a person spends on gas based on how far their daily commute is. We could also calculate different scenarios if fuel prices rise in the future. This makes an economic case for 1. taking the bus and/or 2. living closer to where you work.
