Research Highlights
Using High-Resolution Bus Detection Data to Improve Travel Time Prediction and Identify Urban Congestion Spots
Miguel Andres Figliozzi
Robert Bertini
Transit travel time, operating speed and reliability all influence service attractiveness, operating cost and system efficiency. These metrics have a long-term impact on system effectiveness through a change in ridership. As part of its bus dispatch system (BDS), the Tri-County Metropolitan Transportation District of Oregon (TriMet) has been archiving automatic vehicle location (AVL) and automatic passenger count (APC) data for all bus trips at the stop level since 1997.

Jennifer Dill
John MacArthur , Nathan McNeil
The objective of this research is to provide a guide for state departments of transportation (DOTs) to better integrate active transportation into the institution’s plans, policies, and processes. The guide will also include a capability maturity model (CMM) to help agencies assess their readiness for improvements. The team is led by Dr. Jennifer Dill at the Transportation Research and Education Center (TREC) at Portland State University (PSU), along with Nathan McNeil and John MacArthur. Par...
