The most expensive and critical links in our transportation network are its bridges. Historical and contemporary bridge failures have highlighted our reliance on these structures. While the nation’s bridge management system is robust and well administered, the tools needed to evaluate individual bridges to determine their condition—whether for asset management or in response to a significant loading event such as the imminent Cascadia Subduction Zone earthquake in the Pacific Northwest— are currently highly specialized.
NITC researcher C.J. Riley, a civil engineering professor at the Oregon Institute of Technology, has developed a cost-effective, accurate, and easily deployed evaluation tool using widely available mobile technology (specifically iPods) to measure the dynamic structural response of a bridge subjected to harmonic forcing....

Vehicle operating dynamics data have a fundamental impact on the design of roadways, but collecting this type of data is not part of your typical college curriculum.
Instead, engineering students are handed a textbook, leaving them without a firsthand experience of how accelerations and decelerations “feel” to the driver, the ultimate consumer of their designs.
Seeking to change this norm, Roger Lindgren and C.J. Riley, civil engineering professors at the Oregon Institute of Technology, undertook a NITC education project to incorporate more real-world data collection and...Read more
A newly published NITC education project offers tools for teaching collaborative regional planning in communities close to national parks and other natural attractions.
Referred to as Gateway and Natural Amenity Region (GNAR) communities, these unique places have their own set of challenges and opportunities. They are often located near small towns or rural areas with limited transportation networks, but due to the periodic influx of visitors, can experience “big city problems” like congestion and sprawl.

To help maximize the implementation of U.S. DOT’s commitment to livable communities, the National Institute for Transportation and Communities (NITC) has launched its third round of pooled fund research funding in 2018. Agency partners are invited to submit problem statements by May 15, 2018.
The pooled fund program offers a process by which cities, counties, MPOs and other regional or local agencies can pool relatively small pots of research dollars to then leverage NITC matched funds for a single, collaborative project.
We held an online information session on February 28, 2018. Watch the video to learn more about the funding process, identifying partners, and crafting an effective problem statement:Read more

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 (Aug 6 - 10, 2018). 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.
