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. In 2014, a new and hi... Read More

Bridge Seismic Retrofit Feasibility Case Study Utilizing Ductile Fuses

Peter Dusicka
In an effort to increase the seismic resiliency of our transportation network, a performance centric retrofit measure has been developed as part of State funded research and evaluated through to large scale laboratory setting. With an eye toward implementation, this technology transfer proposal aims to conduct a feasibility study on incorporating this retrofit measure with a recently developed ductile fuse technology and applying the retrofit to a real bridge case study. The intent is to deve... Read More
