Alex Bigazzi, a 2014 NITC dissertation fellow and graduate of Portland State University's Civil and Environmental Engineering Ph.D. program, has published a paper based on his NITC-funded research in Environmental Science & Technology, a journal of the American Chemical Society (ACS).
See ACS coverage of the project here.
Bigazzi's research evaluates the concentration of air pollution encountered by cyclists in Portland, Oregon.
In the study, volunteer research subjects rode bicycles equipped with instruments to collect high-resolution bicycle, rider, traffic and environmental data.
Participants rode a variety of routes including bicycle lanes on primary and secondary arterials, bicycle boulevards, off-street paths and mixed-use roadways. They were told to ride at a pace and exertion level typical for utilitarian travel, and breath biomarkers were used to record the amount of traffic-related pollution present in each cyclist’s exhalations.
This research was the focus of Bigazzi's dissertation, Bicyclists’ Uptake of Traffic-Related Air Pollution: Effects of the Urban Transportation System, published by NITC in December 2014. It was related to an earlier project...Read more
The City of Portland and the Metropolitan Region have strong policies in place to encourage transportation through means other than the single-occupancy vehicle. Both governments have numeric goals for the proportion of trips to be made by walking, bicycling, transit, shared vehicles, working at home and driving alone. Indeed, the City of Portland desires that by 2035 no more than thirty percent of commute trips be made by people driving alone. Similar policies have driven transportation planning in the city and region for decades.
To understand if these policies will be effective it's necessary to understand whether their antecedents have been effective. The Portland region has been investing in transit, bicycling and walking for more than two decades? Are we moving the needle? Have we been effective?
Roger's presentation will take a look at regional data for the period 2000-2014 to assess the effectiveness of our efforts and use that information to suggest pathways forward.
Roger Geller has been Portland, Oregon’s bicycle coordinator since 2000 and has been...Read more

Oregon, and Portland in particular, is internationally known for its love for bikes. Not only does the region have some of the highest bike ridership in the nation but the Oregon bike manufacturing industry is quickly growing as well. Oregon’s electric bike (e-bike) market is also growing, but little data are available on the potential market and e-bike user behavior and interest.
Only a limited amount of research has explored the potential new market segments for e-bikes and the economic, operational, safety, and transportation issues surrounding e-bikes in the United States. This webinar will present findings from a research project evaluating e-bike use at three Kaiser Permanente employment centers in the Portland region.
The project's primary goal was to test user acceptance of electric-assist folding bicycles as a commuting solution.
Some researchers have tried to categorize cyclists’ levels of traffic stress utilizing facility or traffic data that can be readily measured in the field, such as motorized travel lanes, travel speeds, and type of bicycle infrastructure.
This seminar will present data and modeling results utilizing two novel data sources:
(a) real-world, on-road measurements of physiological stress as...Read more
Seven dedicated students spent their summer days in TREC’s offices at PSU this year, working to transform the Bike-Ped Portal project from a dream into a reality.
TREC already houses Portal, a vast collection of Portland-area traffic and transit data, and NITC researchers saw a need for a database on the national scale for non-motorized transportation modes.
Research associate Krista Nordback launched the NITC pooled-fund project, Online Non-motorized Traffic Count Archive, with co-investigator Kristen Tufte in the spring of 2014. A year ago, Bike-Ped Portal was little more than an idea.
Now it contains roughly four million individual records of bicycle, pedestrian and even equestrian movements in five states.
High school interns Jolene Liu, Tomas Ramirez, Tara Sengupta, Gautum Singh, Kim Le, Max Fajardo and Kimberly Kuhn worked full time for weeks in order to convert piles of unsorted documentation into usable formats.
Nordback engaged the team of interns through Saturday Academy, a program affiliated with the University of...Read more
Strong and Fearless | Enthused and Confident | Interested but Concerned | No Way No How
Originally developed by Roger Geller for the city of Portland, the “Four Types of Cyclists” typology (Strong and Fearless; Enthused and Confident; Interested but Concerned; No Way No How) has been adopted widely to help guide efforts to increase bicycling for transportation. This webinar will present findings from a new, national survey conducted in collaboration with the National Association of Realtors. In Portland, 60 % of the population falls into the "interested but concerned" category, and they represent a promising segment of the population in terms of increasing the bicycle mode share. In this webinar, we will address the following questions:
- Does the Four Types of Cyclists typology apply nationally?
- What are the characteristics of each type of cyclist?
- How does the existing environment, including bicycle infrastructure, affect the share of people in each category/type?
- What programs or infrastructure might increase bicycling for transportation among the...
