Greetings DIY Portland. Wanted to post a link to your group in case you missed it in the Discussions or Main group: DIYtraffic, launched a few weeks ago (and still in deep beta) has a version running for Portland:
Live heterogeneous feed of traffic alerts to your Twitter account. You can query it for info on a specific street or highway and get the results DM'ed to your phone.
Details on how to use it, how to extend it, etc, here:
New versions on their way.
Enjoy, use, give feedback, make better.
