Hey Folks! I am looking for help in visualizing theoretical public transportation routes for a given US metropolitan area.

We have pretty lackluster service and I want to poll the public and ask them where they commute to.

Questions would be something like:

1. What neighborhood do you live in (field/drop-down)
2. Enter up to 3 locations you frequent in a month that you would prefer to take public transportation on (address field) 2a. how often do you commute to location 1-3 (daily, weekly, monthly)
3. What is your current commute time in minutes (integer)

Given this data, how could I process/visualize these trends? I would like to say "wow! A lot of people need rapid transport from towns A <-> B and towns B <-> C but not so much for towns A<->C!"
