Last year, a car driver hit a César Chávez K-8 School student at the intersection of N. Portsmouth Ave and N. Willis Blvd in Portland, OR. It underscored what parents, teachers and Portland community members have been demanding for many years: increased investment in traffic safety at schools during pick up and drop off hours.

What’s more: Portsmouth’s residents already had a lot of ideas of how to improve pedestrian safety at this intersection.

Seeking to help the community take action on these ideas, Safe Routes to School advocacy professionals William Francis and Hanna Howsmon at Community Cycling Center and César Chávez teacher Sam Balto recommended this intersection as a potential quick build project for the Better Block PSU pathway program-–a partnership between the volunteer-led group Better Block PDX and the Transportation Research and Education Center (TREC) at Portland State University that pairs transportation students with community-led projects. 

“PSU students support community members with the technical aspects of infrastructure improvements–elevating and materializing their ideas by developing plans, designs, and engineering concepts. It’s a shift from the status quo with a ground-up approach, and their transportation expertise can help community members in navigating the permit process or proposing informed solutions to the city,” shared Hau Hagedorn, TREC Associate...

We're proud to announce the publication of a new NITC dissertation: "Methodologies to Quantify Transit Performance Metrics at the System-Level," by Travis Glick of Portland State University.

Performance metrics have typically focused at two main scales: a microscopic scale that focuses on specific locations, time-periods, and trips; and, a macroscopic scale that averages metrics over longer times, entire routes, and networks. When applied to entire transit systems, microscopic methodologies often have computational limitations while macroscopic methodologies ascribe artificial uniformity to non-uniform analysis areas. These limitations highlight the need for a middle approach. This dissertation presents a mesoscopic analysis based around timepoint-segments, which are a novel application of an existing system for many transit agencies.

In the United States, fix-route transit is typically defined by a small subset of bus stops along each route, called timepoints. For this research, routes are divided into a consecutive group of bus stops with one timepoint at the center. Each timepoint-segment includes all data collected in that segment during one hour of operation. Visuals for congestion and headway performance, based on the aggregated datasets, are designed to...

Since 2013, local transportation activist group Better Block PDX has developed partnerships with organizations across the Portland Metro area. Most notable were the connections that emerged between the communities’ needs for creative transportation solutions and the expertise of Portland State University (PSU) transportation students.

That collaboration evolved into Better Block PSU, a pathway program led by PSU’s Transportation Research and Education Center that integrates tactical urbanism and placemaking into the engineering and planning curriculum at PSU. Most recently we shared an update on Re-Imagining a Safer Route to the César Chávez School, which advanced to the Spring 2021 engineering capstone.

We’re excited to announce the latest projects to have been accepted into the Better Block PSU pathway program:

• City of Independence Neighborhood Greenways: This project will help create a low-stress biking and walking network through Independence connecting local schools, businesses, and parks.
• Community Green Space for Parkrose: This project plans to create a pathway from the Parkrose neighborhood to the Columbia Slough to increase access to green space and community knowledge of the Slough.
• Arleta Triangle Transformation...

The National Institute for Transportation and Communities (NITC) is proud to introduce a new dissertation fellow: Kelly Rodgers of Portland State University. Four other NITC dissertation fellows were announced in summer 2020. Our NITC Dissertation fellowships applications are accepted on a rolling basis. 

Kelly’s dissertation project will focus on "The use and influence of health indicators in transportation decision-making."

Research on health and transport has increased significantly in the past 20 years, both across health and transportation fields. Researchers and practitioners have called for the use of health indicators in transportation, which come amidst the growing emphasis on the use of indicators for transportation plans and projects in general. The underlying hope is that new procedural arrangements, such as measuring and tracking indicators, can turn policy goals into practice. This research project will explore the use and influence of health indicators in transportation using a mixed methods approach.
