Tri-County Metropolitan Transportation District of Oregon (TriMet) serves a population of approximately 1.8 million in 533 square miles of the urban portion of the three-county Portland metropolitan area through rail and bus routes. TriMet has planned to extend its open trip planner project (OTP), an integration of transit, bicycling, and walking. The OTP project was designed to enhance the existing TriMet trip planner to include shared-use mobility (SUM) options, real-time information on transit vehicle arrivals, accessibility, pedestrian routing in consideration of sidewalks, and other interface enhancements. The project also implemented a fully functional and comprehensive open geocoder to advance a non-proprietary system for geocoding that could lower the costs for implementing a trip planning system. This report presents the results of the independent evaluation (IE) that explored the technical function of the OTP, including geocoding, routing, and data veracity as well as user responses through a survey. Expert interviews with project participants were conducted to assess lessons learned from the project operation.
