FEBRUARY 2018 UPDATE
The full final report on this project is now published. The final report offers a comprehensive look at six case study states' strategies to ensure they are delivering value to taxpayers in a transparent process.
What do Americans get in return for their transportation investments? It’s a simple enough question on the surface, but digging for an answer yields a gnarled knot of...Read more
The third and final phase of our bike share equity research project has been published, with new findings from a survey of bike share users.
Riders targeted for equity-focused outreach efforts—lower-income individuals and people of color—were most likely to cite cost savings or discounted membership as reasons why they joined, while higher-income and white users were more likely to cite the convenience of using bike share. Lower-income riders were also more likely to have heard about...Read more
The National Institute for Transportation and Communities (NITC) program has released its 2018 general research request for proposals. Faculty at NITC's partner universities* are invited to submit abstracts by April 2, 2018.
Through funding provided by the U.S. DOT, we will award at least $1 million under our general research grant in 2018 for projects that support NITC’s theme: improving mobility of people and goods to build strong communities. Our theme includes a few key topics:
- Increasing access to opportunities
- Improving multi-modal planning and shared use of infrastructure
- Advancing innovation and smart cities
- Developing data, models, and tools
Research projects must focus on transportation, with additional consideration given to projects that emphasize equity and diversity in their research and partnerships. We’re seeking projects that demonstrate a strong potential to move transportation research into practice, shape national and international conversations, and respond to the needs of practitioners and policymakers.
Priority is given to projects that are collaborative, multidisciplinary, multi-campus, and support the development of untenured-tenure-track transportation faculty.
- Abstracts due: April 2,...
Every year NITC offers Doctoral Dissertation Research Fellowships which cover expenses for the recipient while working on a dissertation consistent with NITC's theme of improving the mobility of people and goods to build strong communities.
Alexander Lee, a Graduate Research Assistant in Systems and Industrial Engineering at University of Arizona, is our 2017 NITC dissertation fellow has been funded to investigate his study on Using Time-Series Analysis to Precisely Identify and Rank Road Hotspots.
Over the past decades, many ranking methods have been proposed for "road hotspots". However, results vary from method to method, and one of the issues behind ranking is the element of subjectivity. One approach to resolve these issues is the use of combined models. One of the combined models is the Enhanced Empirical Bayesian (EB) method that incorporates the use of the similarity measure based on the Proportion Discordance Ratio (PDR). This model is developed to assess and objectively quantify similarity among road segments based on crash patterns, each of which contains a unique combination of selected crash-related features....

A NITC education grant funded a new course for planners, engineers, scientists and students to help improve their data processing workflow.
Liming Wang, an assistant professor in the Toulan School of Urban Studies & Planning at Portland State University, is on a mission to simplify data processing. A NITC education grant supported his efforts to develop a new course: Introduction to Data Science. The course is designed to help students and professionals to improve their workflow for data-intensive research. The course covers how to collect data, clean them up, visualize, explore, model and eventually compile the data with findings in a report.... Read more

Tell us about yourself:
My name is Alex Bigazzi and I am an assistant professor, joint-appointed in transportation engineering and planning at the University of British Columbia in Vancouver, Canada. My main research areas are transportation emissions and air quality and active travel.
Why did you decide to attend Portland State University?
The original decision was driven almost entirely by location. I was living in Portland, decided to go back to school for a second...Read more
Researchers Robert Hibberd and Arthur C. Nelson at the University of Arizona are investigating the jobs-housing balance in transit neighborhoods. They're looking to identify patterns in the way that jobs and housing have concentrated near transit over time.
The paper they'll be presenting at this year's TRB annual meeting specifically looks at Chicago, before and after the great recession of 2008.
In the early 2000s, lower-income jobs were concentrated closest to transit. Higher-income jobs were spreading out to the suburbs, following the sprawl of development. The housing recession of 2008 seems to have caused that pendulum to swing back: from 2009 to 2014, higher-income jobs began crowding into the suddenly more competitive transit-adjacent areas.

An Update On Jordan at TRB:
NITC Student of the Year Jordan Preston attended TRB's annual meeting in 2018, and we had a conversation with her about the experience. Here are a few of her thoughts.
Do you have a funny story/enjoyable experience from TRB 2018 to share?
One of the highlights of my TRB experience was renting bikes with the rest of the Oregon Tech attendees and using the (awesome!) separated bike lanes to see a bit of Washington D.C. at night. Not only was I interested in actual bike lanes due to my various research projects, it was also just a great time with the professors and students to have a bit of fun!
At TRB 2018, which session(s) stood out/stuck with you the most?
I particularly enjoyed the poster sessions about bicycling, with content ranging from bike share usage to facility construction to parking shortages. Not only did I end up with an extensive list of articles and projects with more information than I can possibly sort through, it was also an...Read more
In the last decade there has been a national trend toward projects that involve roadway space reallocation across modes. "Road Diets," in which one or more travel lanes are removed to make space for wider and safer bicycle and pedestrian space, is a common type of roadway reallocation.
A new NITC report by Miguel Figliozzi and Travis Glick of Portland State University offers a new methodology for doing before-and-after studies of these projects using high-resolution transit data. The data used in this project was supplied by TriMet, the transit provider for the Portland, Oregon metropolitan region.
Typically, before-and-after studies of roadway changes have used data on vehicle speeds to determine effects of change, without considering transit. By using datasets from transit providers, researchers can measure transit and also general traffic speed, so the data serve both purposes.
"This is a new methodology; something that no...Read more
