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...

Monday is the first day for lectern and poster sessions at TRB. Researchers from universities affiliated with the National Institute for Transportation and Communities program have 12 presentations on the day's schedule.

Chris Monsere of Portland State University presents "Operational Guidance for Bicycle-Specific Traffic Signals in the United States" at an 8:30 a.m. poster session in Hall E (all listed rooms are in the Walter E. Washington Convention Center). The poster is part of a state department of transportation high-value research session.

Last July, the project, led by Monsere with co-investigator Miguel Figliozzi, was honored as a "Sweet Sixteen" project by the Research Advisory Committee to the AASHTO Standing Committee on Research. Each year, the committee collects High Value Research highlights from member states across the country. From these, each of the four RAC regions selects its top four projects to form the Sweet Sixteen. 

More information on the research is on the project page.

Sunday, the first day of the Transportation Research Board annual meeting in Washington, D.C., is workshop day. Portland State University doctoral student Tara Goddard presents in a showcase of research stemming from the prestigious Dwight D. Eisenhower Transportation Fellowship program.

Goddard probed the question of why so many bicyclists die in traffic crashes. Cyclists are 12 times more likely to be killed in a crash than a driver or passenger in a car. She wondered what role drivers' attitudes toward cyclists might play.

Goddard's research uses a survey to measure drivers' attitudes and self-reported behaviors and to test drivers' implicit attitudes toward both other drivers and cyclists. She pairs the survey piece with a lab experiment that uses hazard-perception video clips to examine whether drivers notice cyclists. 

By this approach, Goddard hopes to understand drivers' attitudes and whether those attitudes can predict how they act on the road. That understanding can potentially lead to steps to improve cyclist safety. Her workshop runs 9 a.m. to noon in Room 202B of the Walter E. Washington Convention Center.

Portland State University today achieved the highest ranking from the League of American Bicyclists' Bicycle Friendly University program. Portland State is now one of just five platinum universities recognized under the program.

Other NITC program campuses were also designated as bike friendly. University of Oregon achieved gold status and University of Utah, silver.

The Bicycle Friendly University program evaluates applicants’ efforts to promote bicycling in five primary areas: engineering, encouragement, education, enforcement and evaluation/planning, known as the Five E's.

The league noted that Portland State’s support for bicycling has helped reduce congestion, improve air quality and lower the demand for parking on campus. “Portland State encourages bicycling as an affordable, efficient option for transportation and provides amenities such as indoor bicycle parking, low-cost bicycle rentals, and an on-campus Bike Hub, where students can find everything they need to make bicycling a part of their commute options,” the league stated.

PSU previously was a gold-level bike-friendly university. In the past two years it expanded its “Vik Bike” bicycle rental program from 12 bicycles to 134. Each bike comes with lights, a lock and a helmet. The program, in which students can rent a bike for a term, receive training on bike commuting and bike maintenance, has a waiting list of participants.

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...

Comprehensive Bikeway Design 1.0, a popular summer workshop offered by the Initiative for Bicycle and Pedestrian Innovation (IBPI), wrapped up to a successful conclusion last week.

Hau Hagedorn, director of the IBPI, has seen the annual workshop grow into a one-of-a-kind training opportunity for bicycle and pedestrian professionals.

“The course is comprehensive. It isn't just about bikeway design. It's about everything a city can do to become more bike-friendly, including policies that support cycling and land uses that encourage active transportation,” Hagedorn said.

With 10 participants from six states, this year’s workshop helped further the IBPI’s goal of expanding America’s bicycle and pedestrian infrastructure to encourage healthier, more sustainable forms of transportation. The participants came from a diversity of disciplines including community and bicycle planning, academic research and political leadership, and traveled from as far away as Pennsylvania to visit Portland’s bicycle culture.

“I think it reaffirms that this is a unique opportunity, for people to come and see what has been done in Portland. This didn't happen overnight. It gives a good idea of what can be done in other places,” Hagedorn said.

The five-day instructional course began on Sunday, July 26, with a tour of...

Millennials prefer walking over driving by a substantially wider margin than any other generation, according to a new poll conducted by the National Association of Realtors and TREC, the Transportation Research and Education Center at Portland State University.

The 2015 National Community and Transportation Preference Survey found that millennials, those aged 18 to 34, prefer walking as a mode of transportation by 12 percentage points over driving. Millennials are also shown to prefer living in attached housing, living within walking distance of shops and restaurants, and having a short commute, and are the most likely age group to make use of public transportation.

The poll also found that millennials show a stronger preference than other generations for expanding public transportation and providing transportation alternatives to driving, such as biking and walking, while also increasing the availability of trains and buses. Millennials likewise favor developing communities where people do not need to drive long distances to work or shop.

> Jennifer Dill of TREC and Hugh Morris of NAR will discuss the findings in a free Webinar Aug. 5....

A project led by Portland State University researchers Chris Monsere and Miguel Figliozzi has been nationally recognized as one of sixteen high value research projects by the American Association of State Highway and Transportation Officials (AASHTO).

Each year at its annual meeting, AASHTO's Research Advisory Committee selects four projects from each of its four regions to form a "Sweet Sixteen" group of important and influential projects.

The project, “Operational Guidance for Bicycle-Specific Traffic Signals,” reviewed the current state of practice for bicycle signals and evaluated cyclist performance characteristics at intersections. The research has been used to inform an FHWA Interim Approval for bicycle signals.

Bike signals are beginning to be common in major cities throughout the U.S., with some engineering guidance available from the California Manual on Uniform Traffic Control Devices, the...

To be published later this spring is some of the first bicycle-focused research into shared space, a controversial urban design approach pioneered in the Netherlands in the 1990s.

Allison Duncan, a PhD candidate in urban studies & planning at Portland State University, earned a NITC dissertation fellowship in 2014 and used the research grant to study shared space intersections in the United Kingdom.

Shared space designs have recently been adopted at a handful of sites in the UK and others scattered across Europe, Australia and New Zealand. They are characterized by a lack of physical guidelines such as curbs, road surface markings and traffic signs to define who has the right-of-way.

The idea is for pedestrians, cars and bicycles to mingle in a common zone and use eye contact and natural communication to make sure no one gets hurt.

“Cyclists and pedestrians are supposed to be able to treat it more like a plaza and just cross where they want to, and drivers are supposed to yield,” Duncan said.

As a street design scheme, shared space isn’t exactly new. It’s more or less the way all streets were designed until the advent of cars, and is still the norm in many Asian countries where cars share the roads with a crowd of two- and three-wheeled...

When Portland State University student Marisa DeMull signed up for the summer 2014 study abroad course in the Netherlands, she wasn't necessarily looking for a new major. A civil engineering student, DeMull thought the summer program just sounded like a great way to get course credit.

DeMull learned that she could get six credits for the two-week program and applied immediately, a week from the deadline.

“I tried spreading the word. It’s the best program, and so few people really know about it, which is unfortunate,” DeMull said.

After two weeks in Delft and a series of lectures, bike tours, and eye-opening conversations, the PSU senior returned home to Portland State and declared a change in her program of study: she would now focus on transportation, a sub-field within civil engineering.

"Until this trip, I didn't really know that was a career choice," DeMull said. "I love riding bikes, but to design bike routes for a living? I met all these engineers who are completely devoted to bicycles, who just live and breathe it."

Practitioners give daily lectures to the students in the course, and...
