Transportation corridors are complex systems. Tradeoffs, particularly in terms of traffic mobility, transit performance, accessibility and pedestrian interactions, are not well understood. When the focus is on motorized vehicle mobility and throughput, high traffic or vehicle speeds are desirable… Read More

In 2016, TREC was part of a team, in partnership with ICF and Alta Planning, that developed the Strategic Agenda for Pedestrian and Bicycle Transportation, a framework to inform future investments, policies, and partnerships and serves as the update to U.S. DOT’s 1994 National Bicycling and Walking… Read More

This project is a collaboration between Portland State University (PSU) and the Center for Infrastructure Transportation & Environment (CITE) at Rensselaer Polytechnic Institute seeking to develop performance measures for assessing the impacts of social media on promoting public transit… Read More

The goal of signal timing at an intersection should be to separate conflicting movements in time, maximizing safety and efficiency for all users. In many jurisdictions, however, signal timing objectives have traditionally focused on allowing vehicle progression and reducing vehicular delay and… Read More

Through a previously funded research project, Encouraging Low-Income Households to Make Location-Efficient Housing Choices, our team developed a toolkit to assist households utilizing Section 8 Housing Choice Vouchers with finding location-efficient/affordable housing. These tools are currently in… Read More

Oregon, and Portland in particular, is internationally known for its love for bikes. Not only does the region have some of the highest bike ridership but the Oregon bike manufacturing industry is quickly growing. Oregon’s electric bike (e-bike) market is also growing but little data are available… Read More

The Investigations in Transportation program is an elementary school partnership and curriculum development project to engage science, technology, engineering and mathematics (STEM) professionals in school-based activities and projects to bring real-world applications to elementary classrooms for… Read More

MAP-21 and state laws are placing increasing emphasis on using comprehensive transportation performance measures that include mobility, safety, economy, livability, equity, and environmental to guide transportation decision-making. One of the toughest challenges keeping DOTs and MPOs from adopting… Read More

This NITC report offers a multimodal framework for transportation impact analysis – a welcome tool for professionals in many cities seeking more detailed data about non-drivers. Headed by Kelly Clifton of Portland State University and Nico Larco of the University of Oregon, this project is the… Read More

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… Read More

Bicycling is enjoying a surge in popularity across the USA but bicycle safety continues to remain a challenge. Cyclists (and pedestrians) are the most vulnerable road users since cyclist-vehicle collisions often result in severe injuries and have high fatality rates with respect to other types of… Read More

Robust bicycle and pedestrian data on a national scale would serve numerous purposes. Access to a centralized nonmotorized traffic count archive can open the door for innovation through research, design and planning; provide safety researchers with a measure of exposure; provide fundamental… Read More
