The folks over at the BTA will like this one. An interesting tool for getting a quick estimate on how much a certain bike facility would cost. (from Velorution)
From the homepage:
How much do bicycle facilities cost? Can we quantify their benefits? In what cases do estimates of benefits outweigh costs?
If your community is considering building a new bicycle facility you can use this tool to estimate costs, the demand in terms of new cyclists, and measured economic benefits (e.g., time savings, increased livability, decreased health costs, a more enjoyable ride, decreased pollution).
