Bicycle and pedestrian safety has emerged as a top priority for U.S. Transportation Secretary Anthony Foxx and the Department of Transportation. With this in mind, the department’s top research official visited Portland State University, home to the U.S. DOT-designated national center for livable communities.

Greg Winfree, the assistant secretary for research and technology, visited Portland State’s transportation research and education center June 13. Center Director Jennifer Dill and researcher Christopher Monsere gave Winfree a tour of the center’s living laboratory: Portland’s active transportation infrastructure.

Winfree, an advocate for improving safety for vulnerable road users, explored the city’s various bicycle safety efforts, including bike boulevards, protected bike lanes, bike boxes, bike-specific signals and signage. He also learned of pedestrian research involving traffic signals, crossings and...

A research study released Monday by the National Institute for Transportation and Communities program offers the most comprehensive evaluation of protected bicycle lanes to date. The study, “Lessons from the Green Lanes: Evaluating Protected Bike Lanes in the U.S.,” examines recently installed protected bike lanes in five of the six founding PeopleForBikes Green Lane Project cities and provides the scientific basis for decisions that could improve bicycling in cities across the United States.

Protected bike lanes, sometimes called cycle tracks, are on-street lanes separated from traffic by curbs, planters, parked cars or posts to help organize the street and make riding a bike appealing for people of all ages and abilities. Because protected bike lanes are relatively new to the U.S., little academic research has existed to help leaders evaluate the risks and rewards of the investment in putting the facilities on the ground.

This study provides definitive evidence that people feel safe riding in protected lanes and that people traveling by car or foot also support building more protected lanes to separate bicycles and automobiles. It also provides insight on the safety, use and economic effect of protected lanes.

THE METHODOLOGY: FIVE CITIES

Researchers visited each of the five...

A team of students from Portland State University took second place this week in the Cornell Cup USA, with a traffic hazard predictor called SAFE.
SAFE, or Situational Awareness Fault?Finder Extension, is an intelligent device that could be used with bicycles, motorcycles, or automobiles, though it was created with the safety of two-wheeled travelers in mind.
The device is designed to enhance a vehicle operator's situational awareness. It tracks the movement of vehicles behind the user, monitoring their position, velocity, and acceleration.

The SAFE creators considered giving the user an overhead representation of the surrounding traffic, with color-coded alerts to signify approaching danger, but felt that that might be too distracting. Citing research that showed that people react more quickly to audio than visual cues, they decided to give the user feedback through stereo audio. 
The device sends a periodic beep to alert the user of impending accidents from the rear. It modulates the stereo, tempo,...

OTREC researcher Miguel Figliozzi details some of the work on an Oregon Department of Transportation project, "Design and Implementation of Pedestrian and Bicycle Specific Data Collection Methods in Oregon," in this video produced by the Federal Highway Administration.

The project reviewed collection methods such as tube counters and loop detectors for accuracy and looked at using count numbers to deterimine average annual pedestrian and bicycle traffic at intersections.

Figliozzi was lead researcher on the project, with Christopher Monsere. Both are associate professors of civil and environmental engineering at Portland State University.

OTREC's Krista Nordback was also involved in the project, as were graduate students Pamela Johnson and Bryan Blanc. More information on the project is at:

The Initiative for Bicycle and Pedestrian Innovation has unveiled the most ambitious year of professional development offerings in its history.

For the first time, the schedule includes Webinars, with the first taking place Feb. 27. Offerings also include courses and workshops geared toward practitioners and university faculty members. There’s also a two-week study abroad opportunity to learn about sustainable transportation in the Netherlands.

The course offerings include a newly added advanced bicycle design and engineering workshop. The workshop is geared toward professionals who have taken the original IBPI course or who serve communities with a developed bicycle network.

“More than 120 professionals have taken the course since 2008,” said Hau Hagedorn, who manages the IBPI program. “We’ve reached the threshold of educating professionals where there’s the need to take this to the next level of expertise.”

Continuing education credits are available for each workshop and Webinar. Click here for details on the individual course pages.

Registration is now open for IBPI’s inaugural Webinar on Feb. 27: “We are Traffic: Creating Robust Bicycle and Pedestrian Count Programs.” As agencies looking to improve bicycle and pedestrian infrastructure have learned, it doesn’t count if it’s not counted....

Note: In advance of the Transportation Research Board's annual meeting, the biggest forum on the transportation research calendar, OTREC.us is profiling some of the researchers who will present their work.

The bicycle counts suggested that, on Bike to Work Day, more people did bike to work. But did fewer people drive?

OTREC staff researcher Krista Nordback took up the issue and will present her findings Monday, Jan. 13 at the Transportation Research Board’s annual meeting in Washington, D.C.

The bike count data from sites across Boulder, Colo., certainly impressed Nordback.  “Bike to Work Day has this huge spike,” she said. “The bike counts double at a lot of the count sites.

“Wouldn’t it be cool if we could see something similar with the motor vehicle count data?”

In a twist that might only happen in Boulder, with its ample bike counters, Nordback had a harder time tracking down the motor vehicle counts. She lucked out, finding that the city’s red-light cameras had been counting cars alongside their primary job of catching red-light runners.

Those motor vehicle counts showed a consistent drop on Bike-to-Work days compared with average workdays in June and July. It was a small drop, but even finding that was unprecedented: no studies had documented a statistically significant drop in motor vehicle counts during any bike-to-work event.

Recently OTREC took a look at suburbia to see how many people were walking and biking to local destinations.
Traditionally, studies of suburban locations have found that due to the low density of suburban areas and their single-land-use patterns, active transportation is rare.
In a research project by Principal Investigator Nico Larco and Co-Investigator Robert Parker, of the University of Oregon, active transportation was found to be more common than expected in suburban areas with commercial strip destinations.
In their project “Overlooked Destinations: Suburban Nodes, Centers, and Trips to Strips,” Larco and Parker observed active travel behaviors around typical suburban commercial sites. They examined six strip malls -- four in Portland, Ore. and two in Atlanta, Ga. -- to map out the “pedshed,” or walkable zone surrounding these sites.
Investigators were surprised by what they found.
For each site, they created detailed pedestrian-network GIS maps. They compared the network extents of maps that included only publicly available, street centerline data with maps that included pedestrian networks derived from...

Most people in transportation circles have heard all about the Netherlands as a bicyclist’s mecca, a place where thirty-five percent of the population regularly commutes by bike. What may be less commonly known is how recent this achievement is.

In 1967, bicycling in the Netherlands was “tantamount to attempting suicide,” according to Amsterdam’s chief inspector of traffic police.

Today, the Netherlands is the safest place in the world to operate a bicycle, based on injury and fatality rates per miles traveled. In less than fifty years, their bicycle safety rates have soared and the Dutch have built a bicycle infrastructure that is the envy of the rest of the world. How did they do it? 

Could Americans possibly do the same?

That’s what Portland State University transportation students aim to find out.

When PSU student Kirk Paulsen signed up to spend two weeks in the Netherlands as part of the first PSU civil engineering study abroad program, he wasn’t sure what exactly he might get out of it, but knew that he wanted to see famed Dutch bicycling facilities for himself. Paulsen was one of seven transportation students in the pilot class of 2011, and now has this to say about the experience:

“This short study abroad course is by far your best opportunity while enrolled at PSU to observe real world...
