By Jennifer Dill, Ph.D.,TREC director -- Much has been written about millennials and their travel choices, both in the popular press and academic journals. The common theme of the storyline in the popular press is that millennials are driving less, owning fewer cars, and/or not getting their driver’s license. As a complement to that, they are early adopters of new modes, such as car sharing, bike sharing, and ridehailing. One assertion is that they would rather be using their mobile device in a Lyft car or on transit, than sitting behind the wheel. While the popular press often attributes these shifts to fundamental changes in attitudes or values, research from academics such as Noreen McDonald tells a more complicated story. McDonald found that economics, both decreased employment and the overall dampening in travel demand, explain much of the decrease in millennials’ driving. Switching modes did not, though attitudes and electronic substitution may account for 35-...Read more
Despite efforts to get more people biking, North America still has low ridership numbers.
The problem? Biking is hard.
A new NITC report by John MacArthur of TREC offers a solution to that problem: e-bikes.
Many people surveyed say that having to pedal up hills and arriving at their destination sweaty are major deterrents to commuting by bike, even when bike lanes and other facilities are there.
Researchers have put a lot of thought into ways to get more people riding bicycles by improving bicycle infrastructure, land use and public engagement. The efforts are largely due to concerns about congestion, climate change and public health.
Comparatively little research, however, has focused on the bicycle itself.
MacArthur and co-investigator Jennifer Dill teamed up with Drive Oregon, Metro and Kaiser Permanente Northwest to provide Kaiser employees with electric-assist bicycles (e-bikes) to use for a trial period of ten weeks. The goal was to see if e-bikes might help overcome some commonly cited barriers to cycling.
The study, Evaluation of Electric Bike Use at Three Kaiser Permanente NW Employment Centers in Portland Metro Region, took place in Portland, Oregon from April 2014 to September 2015. A total of 150 Kaiser employees participated in the study. Fewer than 10 percent of...Read more
A new NITC report offers a multimodal framework for transportation impact analysis – a welcome tool for professionals in many cities seeking more detailed data about non-drivers.
Improving Trip Generation Methods for Livable Communities, a research project headed by Kelly Clifton of Portland State University and Nico Larco of the University of Oregon, is the latest effort in an ongoing collaboration to create more open sourced, widely available data about non-motorized road users.
Over the last decades, cities have become more invested in fostering the conditions to support walking, biking and public transit.
The land development process presents a unique challenge.
Prior to a zoning change or new development, someone has to determine what its impact on the transportation system will be, and whether upgrades will be necessary to accommodate travelers to the new destination. Trip generation is the first step in the conventional transportation forecasting process.
Current trip generation methods used by engineers across the country tend to focus on motorized modes.
Without reliable trip generation rates for anyone but drivers, the transportation impact is difficult to predict. Certain land uses will draw far more walkers,...Read more
Car crashes are still a leading cause of death in the United States, with vulnerable road users like bicyclists and pedestrians being injured or killed at rates that outpace their mode share.
Planners, engineers, and advocates are increasingly adopting Vision Zero and Tactical Urbanism approaches and trying to better understand the underlying causes of dangerous roadway interactions. However, existing research into crash causation has focused on instrumental factors (e.g. intersection type, vehicle speed) while little research has probed the role of attitudes or socio-cognitive mechanisms in interactions between roadway users.
Social psychology suggests that attitudes and social cognitions can play a role in conflict. Drivers’ attitudes toward bicyclists, and how those attitudes may affect drivers’ behavior, are a largely unexplored area of research, particularly...Read more

Heard of Vehicle Miles Traveled (VMT)? Wouldn’t it be great to know the corresponding value for walking and cycling?
This webinar discusses options for estimating the miles people walk and bicycle on the state-wide level, by investigating the practical considerations of trying to compute these values for one study state.
What strategies can be used, and what data sources do these require?
How do these strategies compare?
How do PMT/BMT estimates vary based on...Read more
To improve safety and increase transit use, transit agencies and the jurisdictions they serve have to approach transit service as door-to-door not just stop-to-stop.
Walking and bicycling are key modes for transit access.
Working with the Federal Transit Administration, a team from Portland State University developed a guidebook on improving pedestrian and bicycle access to transit (forthcoming). As part of the guidebook process, the PSU team conducted case studies on best practices of recent efforts in Minneapolis, Los Angeles and Atlanta.
In the spring of 2015, with guidance provided by the NITC program, students at Hobart and William Smith Colleges in Geneva, New York created a pedestrian and bicycle plan for the City of Canandaigua, New York.
As part of their Sustainable Community Development capstone course, the students in environmental studies provided plans for a mixed use district along Route 332 in Canandaigua.
Course instructor Jim Ochterski credits PSU researcher Lynn Weigand’s NITC education project, Enhancing Bicycle and Pedestrian Education through Curriculum and Faculty Development, with providing essential resources for the course.
“Most of the students did not have any grounding in pedestrian planning and development, and [the NITC materials] made a huge difference,” Ochterski said.
Part of the mission of the NITC program is to enrich transportation education. One way our university partners do this is by developing curricula to advance transportation and livability goals in the classroom.
Weigand's project was intended for just this purpose. She created a module-based curriculum for bicycle and pedestrian planning and design that was designed to be adaptable for use in a variety of course offerings.
The HWS instructors took that curriculum and ran with it.
“We took on a major community project in ped/bike planning because we had these support materials from the program. It allowed us to...Read more
