Active transportation investments offer many types of benefits related to safety, reduced greenhouse gas emissions, physical activity and the economy. Metro, Oregon’s regional government for the Portland metropolitan area, wants to better understand the role of these investments in building stronger communities in their region, and in implementing the Metro 2040 Growth Concept.

Led by Portland State University in partnership with Metro, the Active Transportation Return on Investment (ATROI) study looked at twelve projects constructed in the greater Portland region between 2001 and 2016. These twelve 2040 Catalyst Projects were evaluated to determine if active transportation investments had significant effects on the local economy. 2040 Catalyst Projects retrofit busy commercial streets with pedestrian-friendly treatments to catalyze economic development within 2040 Centers,…

Incorporating transportation into the land development process is a big undertaking, with many important angles to be considered. Researchers are translating NITC research on this theme into a popular, easy-to-understand graphic format: comics. Led by an interdisciplinary team at Portland State University and the University of Arizona, they're illustrating transportation considerations in the land development process as a comic to reach a broader audience on this critical topic.

Still in development (the images here are early working drafts, illustrated by PSU student Joaquin Golez and Portland, OR illustrator Ryan Alexander-Tanner), the comics are based on research findings from s…

Would monetary incentives encourage more people to buy e-bikes? 

Portland State University (PSU) researchers are examining how purchase incentive programs can expand the current e-bike market, and the latest product to come out of this research is a white paper released earlier this month: “Using E-Bike Purchase Incentive Programs to Expand the Market – North American Trends and Recommended Practices (PDF)”

The paper offers methods of identifying the most effective program structure for the incentive provider's priorities, and helpful information on how to administer and track the program. 

A great number of cities in the United States have cycling goals, and a great way to address those is by promoting e-bikes, because they provide for a much wider range of users than a traditional bike does," said Came…

Better Block PSU is a partnership program between the volunteer-led group Better Block PDX and Portland State University - encouraging everyone to imagine what spaces could be when they are designed for people. Once a year, community members submit their project ideas to the Transportation Research and Education Center (TREC) at PSU. Selected projects are then integrated into a pathway of PSU planning and engineering classes, through which students gain hands-on experiential learning by developing plans, designs, and engineering solutions. 

Students in PSU's Pedestrian and Bicycle Planning course, taught by Drusilla van Hengel, are currently working on the newest slate of projects. The course seeks to provide each project partner with an evaluation of each site's level of pedestrian and bicycle activity and existing conditions, a community e…

An Oregon Department of Transportation (ODOT) report, Resilient and Rapid Repair Measures for Seismically Vulnerable Bridges Following Major Earthquakes, introduces a rapid repair method for bridges in the event of a major earthquake.

The Cascadia Subduction Zone earthquake threatens bridges across the Pacific Northwest. Damage is expected to be geographically spread throughout the region and will have a nearly simultaneous impact on transportation through several important corridors. While bridge repair and replacement will ultimately be needed, an immediate priority will be resuming mobility. With that in mind, the project team developed a method for repairs to be implemented quickly.

The quick repair involves encasing a damaged bridge column in a steel jacket, which is then anchored to the found…
