NITC researchers Stephen Fickas and Marc Schlossberg of the University of Oregon are on a mission: bring the benefits of V2I (vehicle-to-infrastructure communication) to bicycling. Earlier this year they published their proof-of-concept of a DIY vehicle-to-infrastructure "bike box" in Oregon for communicating with traffic signal controllers. In the most recent round of NITC grants awarded...Read more

The "Fast Track" project at the University of Oregon focuses on a mode of transportation that is sometimes left out of vehicle-to-infrastructure, or V2I, conversations: Bicycling. NITC researchers developed an app based on a new technology being integrated into modern cars: GLOSA, or Green Light Optimized Speed Advisory. GLOSA allows motorists to set their speed along corridors to maximize their chances of catching a "green wave" so they won't have to stop at red lights.
This project demonstrates how GLOSA can be used by bicyclists in the same way it is used by motorists, with a test site on a busy car and bike corridor feeding the University of Oregon campus: 13th Avenue in Eugene, Oregon. Researchers developed a smartphone app that tells a cyclist whether they should adjust their speed to stay in tune with the signals and catch the next green. The project demonstrates how university researchers, city traffic engineers, and signal-controller manufacturers can come together to help bicyclists be active participants in a smart transportation system....

Most people who bike for transportation can probably think of "that one intersection:" The light where it's impossible to get a green without waiting. Even when there are no cars, pedestrians or other bikes in sight, you still know you'll have to stop and wait a while, sacrifice all your momentum, and wish you could have given the signal advance notice that you were coming.
Researchers at the University of Oregon have created an app for that.
Lead investigator Stephen Fickas, a computer and information science professor at the UO, developed the app, along with a specially-designed Bike Connect ‘box' (watch the 3-minute video) that attaches to a traffic signal controller. With the box installed, the app allows a cyclist to alert the signal that they're...Read more
The National Institute for Transportation and Communities (NITC) is excited to announce the publication of a new visual design guide, "Rethinking Streets for Bikes." Focused on case studies in the U.S., the guidebook will make it easier for North American city officials to design streets with bikes (and the people on them) in mind. ...Read more

The Federal Highway Administration issued an interim approval for bike signals, based on the NITC project "Operational Guidance for Bicycle-Specific Traffic Signals." The project, selected in 2015 as one of AASHTO's "Sweet Sixteen" high-value research projects, has been widely cited and the research is instrumental in beginning to standardize the use and design of bicycle signals.
This video provides a look at what that means for jurisdictions in the United States:
A new NITC report introduces an important tool for safety analysis: a naturalistic method of data collection that can be used to improve the cycling experience.
Before now, most naturalistic studies (studies where data are collected in a natural setting, rather than a controlled setting) in bicycle safety research have been captured by stationary cameras and haven't followed cyclists along a route.
Researchers in this study used first-person video and sensor data to measure cyclists' reactions to specific situations.
Safety research in general has advanced significantly through naturalistic driving studies, which gather data from real drivers to illuminate the causes of traffic incidents both major and minor. For motorized vehicles, the U.S. Department of Transportation has been developing portable, vehicle-based data collection technologies since the early 1990s.
Their report, Utilizing Ego-centric Video to Conduct Naturalistic Bicycling Studies, offers a successful method for integrating video and sensor data to record cyclists...Read more
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
Protected bicycle lanes have gained popularity as a safer way to get more people cycling. Earlier research from the Transportation Research and Education Center, TREC, at Portland State University showed that people feel safer in lanes with a physical barrier between bicycle and motor vehicle traffic.
The research hadn’t closely studied the intersections, where the barriers—and the protection they offer—go away. With little research guidance, agencies across the country could face the prospect of using untested approaches or avoiding protected lanes altogether.
TREC, through its National Institute for Transportation and Communities pooled-fund program, is now addressing intersections for protected lanes. The program lets agencies and interested partners invest small amounts to join research with a national impact. For this project, 11 partners each put $5,000 to $50,000 toward the $250,000 cost.
The project will help agencies decide which intersection treatments to use in which cases, and what elements each should include. Toole Design Group will work with the Portland State research team to tailor the results to practitioners.
“Right now, it’s based on their judgment,” said...
