While attending Oregon's Annual Active Transportation Summit, I found out about the following websites. I thought that they may be useful for people thinking about cycling in Oregon.

Ride Oregon-- Useful information for folks thinking about cycling in Oregon, and even for some of us who have been here for awhile.
http://rideoregonride.com/

Google Transit-- Multi-modal information. This may also be available in many locations. There is some information in the data base now, and it should get better in the future.
