Bike-Ped Portal: Making the Most of Nonmotorized Data
In recent years, cities and counties all across the United States have invested in bicycle and pedestrian counters. Having reliable data on non-motorized traffic can help jurisdictions make informed decisions about infrastructure investments, measure the effectiveness of biking and walking initiatives, and improve safety.
But having a bike-ped count program is just the beginning.
Once counts have been collected, cities face new challenges. How can multiple agencies share data among themselves? How can data be standardized and compared? And what is the most effective way to communicate what the numbers mean?
Enter Bike-Ped Portal, the comprehensive non-motorized data management system for manual and automated non-vehicular multi-modal counts housed at Portland State University (PSU). This specialized data lake and management system is designed to make sharing data—within an agency, with partners at other agencies, and with the public—easily accessible. The newest feature we've added is a regional dashboard for the Portland, OR and Vancouver, WA metropolitan area.

Last month at Portland State University (PSU), two students showcased their work on transportation topics in a Summer Research Symposium held by the Virtual Alternative Research Experience for Undergraduates (altREU) Site on Computational Modeling. The altREU program, led by PSU Engineering & Computer Science professor Christof Teuscher, is funded by the National Science Foundation (NSF) and offers undergraduates experience in designing, programming, and using computers to benefit society.
While students in the altREU program worked on subjects ranging from crime analysis to predicting stock market trends, two participants chose to focus their efforts on multimodal transportation. Linden Faye and Allie Hopper dedicated their time in the ten-week program to autonomous vehicles (AVs) and nonmotorized data, respectively. Learn more about their projects below, and join us in congratulating these two students on their excellent work!

As plans move forward for an earthquake-ready replacement of Portland's Burnside Bridge, several Portland neighborhood associations and the Better Block PSU program are taking the opportunity to reimagine a segment of West Burnside street.
With bridge closure and construction anticipated to begin as early as 2026 and last for several years, the temporary period of reduced traffic on Burnside will offer a unique chance for the neighborhood to test out some designs and placemaking strategies aimed at making the area more people-friendly.
"Currently, West Burnside street acts as a barrier separating the northwest and southwest portions of the Central City from each other, and discouraging movement between them," said Xavier Stickler, chair of the Downtown Neighborhood Association's Land Use and Transportation Committee. He, along with Sean Sweat of the Pearl District Neighborhood Association and Mary-Rain O'Meara of the Old Town Community Association Board, applied to the Better Block PSU program to request the assistance of Portland State University students with connecting those neighborhoods and making Burnside more pedestrian...

Transportation networks are a vital lifeline essential to the functionality of modern society. A newly published research report offers a new methodology for assessing transportation network vulnerability and resilience, with a particular focus on incorporating social vulnerability into the analysis.
Why? Vulnerable populations—such as people with low income, minorities, or seniors—could suffer higher levels of adverse impacts from disruptions. Road closures and other transportation network interruptions due to earthquakes, floods or other disasters may disproportionately affect these groups of people.
The research project, "Integrate Socioeconomic Vulnerability for Resilient Transportation Infrastructure Planning," by Liming Wang, John MacArthur, and Yu Xiao of Portland State University (PSU), addresses a critical gap by integrating socioeconomic vulnerability indicators into the evaluation of transportation infrastructure vulnerabilities.
The report demonstrates this novel methodology using the Portland, Oregon metropolitan area as a case study.
WHAT DOES THE METHODOLOGY OFFER?
The new methodology proposed by the research team combines spatial analysis, network modeling, and social vulnerability indices to identify critical links in the transportation system. It assesses the impact of potential disruptions on accessibility to...

Not far from Portland State University, down a little road tucked under three highway overpasses, sits the International School of Portland (ISP)—a leafy four-acre campus serving nearly 400 students from preschool to fifth grade. Despite its proximity to popular pedestrian areas, including the Downtown Waterfront, the International School of Portland is nestled amongst a few private blocks and can be difficult to access by foot or by bike. Naturally, most students arrive by car, which creates the familiar traffic jam at pickup and dropoff times.
To provide more transportation options and give the students more access to the school's surrounding neighborhood, Portland State University students are working to improve walking and biking access to the campus. Championed by ISP’s volunteer Green Team, Facilities Manager...

Since 2011, Portland State University and the Initiative for Bicycle and Pedestrian Innovation have offered a unique opportunity to students: a two-week study abroad course that introduces participants to cities with stellar bike cultures. In past years, classes have explored the Netherlands, Sweden, and Denmark. This year’s class of eight students, led by Hau Hagedorn and Drusilla van Hengel, spent two weeks this summer traversing Denmark by public transportation, foot, and (of course) bike. Check out some photos from the trip.
Students came from all over the country—from Portland to Connecticut—to attend the course. What they all had in common was a desire to learn from a city that is renowned to have some of the best bike infrastructure in the world. The students wanted to bring their newfound knowledge back to their respective towns to make the world a safer, happier place for their loved ones and communities.
Ern Tan—the founder of Civic Cincinnati, a grassroots urbanism advocacy group in Ohio—said before the trip that she was looking forward to seeing the promise of a more bikeable future for Cincinnati reflected in...

Knowing how many people use walking and bicycling infrastructure is crucial for transportation planning. Active transportation projects can help cities and states achieve multiple climate- and public-health-related targets, and a new project launching in 2024 can help further those goals: California is getting a statewide active transportation count database.
With help from Portland State University (PSU) researcher Sirisha Kothuri, the Safe Transportation Research and Education Center (SafeTREC) at the University of California, Berkeley is leading an effort to create a centralized data repository for the state.
Kothuri, a senior research associate in civil and environmental engineering at PSU, has led multiple research projects aimed at improving the accuracy and scope of nonmotorized data collection efforts. She has experience with using data fusion techniques to estimate bicycle volumes, leveraging crowdsourced data to derive pedestrian counts, and working with this data to make walking and bicycling safer and more comfortable. Her expertise in this area, as well as PSU's experience centralizing transportation data via the university's PORTAL and BikePed Portal, will...

When Kyu Ri Kim was seven years old, she was struck by a car while walking in her neighborhood where there was no separate walkway for pedestrians in Seoul, South Korea.
Kim, who is now an adjunct research associate at Portland State University (PSU), received nerve damage in her legs and had to use a wheelchair for several days after the incident. This experience launched her interest in pedestrian safety, which eventually led to her 2024 doctoral dissertation research project: "The Central Role of Perceived Safety in Connecting Crash Risk Factors and Walking Behavior."
"That was the real starting point, my personal experience. And I'm curious whether other people really do understand the real risk around them. What are the crash risk factors around them and how are they different from individual perceived risk?" Kim said.
Her dissertation, supported by funding from the National Institute for Transportation and Communities (NITC), illuminates the relationship between pedestrian crash risk factors and perceived safety, as well as the relationship between safety attitudes and walking behavior. How the interplay between these factors influences people's behavior...

Drones, or unmanned aerial vehicles (UAVs), are increasingly being used to deliver medical supplies and other goods. In the U.S., where e-commerce grew by 30% rate in 2020, drone deliveries are expected to become a 7 billion US dollar market by 2027.
Two recent publications by Miguel Figliozzi of Portland State University (PSU) explore different aspects of optimizing and improving upon the use of UAVs for e-commerce deliveries.
Figliozzi is a professor of civil and environmental engineering and a member of the Transportation Research Board on Urban Freight committee, and his main research areas are transportation systems modeling, statistical analysis, and optimization. He has published a number of papers analyzing drone delivery and other areas of freight transportation.
WHAT DO TECHNOLOGICAL IMPROVEMENTS MEAN FOR DELIVERY DRONES?
Though many studies have proposed several different types of models for drones, there is a lack of understanding of the current and future limits of drone technologies for deliveries.

This year, residents of 37 new apartment buildings in the Portland area are receiving surveys in the mail. The reason? Portland State University researchers are requesting information about how they travel.
Knowing how residents of these high-density affordable and mixed-income housing developments get around town is key to guiding future development in the metropolitan area.
Metro—the regional government of the Portland, Oregon area—strategically invests in transit-oriented development, or TOD, to help more people live in neighborhoods served by high-quality transit. In a partnership going back nearly twenty years, PSU has supported the Metro TOD program by collecting data on residents' travel habits. This latest round of surveys will add to a knowledge base that has been useful for both Metro and PSU, for several reasons.
WHY COLLECT TRAVEL DATA FROM TOD RESIDENTS?
Using this information, Metro can refine its TOD funding program model to ensure that future developments achieve intended outcomes.
Patrick McLaughlin, senior development project manager for housing and transit-oriented development at Metro, joined the TOD project in April 2016. Part of his job is to assign gap funding to affordable housing projects...
