The day has finally arrived! TriMet's New Trip Planner has emerged from beta and is now available at ride.trimet.org. It is a multimodal trip planner (it plans biking, walking, and bike-to-transit trips as well as transit trips), and was built using open-source technologies like OpenTripPlanner, OpenLayers, PostGIS, and GeoServer, amongst others.
And of course, the map and routing data is from OpenStreetMap (from just last week, no less). I've considered myself very lucky to be paid for all the time I've spent improving OSM in the Portland, Oregon area and it's really exciting to see my (and my coworkers') hard work go into service helping the public get around the city.
