Why did the pedestrian cross the road? TRB 2014

Jan 07, 2014

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.

How long is too long to wait for the light to change? At stoplights, pedestrians often experience longer delays while cars are given priority.

To design traffic signals that serve the needs of walkers, planners must understand the motivations behind pedestrian behaviors.

Working with professors Kelly Clifton and Christopher Monsere, Sirisha Kothuri of Portland State University created a survey designed to shed some light on what makes pedestrians decide to follow, or not follow, traffic laws.

To collect data, Kothuri and a team of graduate students armed with an 11-question survey posted themselves at four different intersections in northeast Portland, Ore.

Two of the intersections had recall signals, where pedestrians are automatically detected, and the other two had actuated signals, where pedestrians must press a button to get the light to change.

Survey respondents were asked for their attitudes about delay in signal timing, and for the reasons that determined their crossing the street.

Researchers interpret clandestine walking paths

Nov 12, 2013

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...

OTREC researchers develop livability metrics for public transit

Oct 14, 2013

The U.S. Department of Housing and Urban Development has identified some “livability principles” which include healthy, safe and walkable neighborhoods and safe, reliable and economical transportation choices.

Transit agencies and local governments routinely use metrics to evaluate the performance of transit systems, but a uniform standard of transit data collection does not exist outside of the reporting requirements of the National Transit Database (NTD). Because of the types of data collected for the NTD, the focus of performance measurements is often on ridership and financial performance, leaving aside the question of livability.

In a new project sponsored by OTREC, Principal Investigator Marc Schlossberg, associate professor in the department of planning, public policy and management at the University of Oregon, along with co-investigators Jennifer Dill of Portland State University and Nico Larco, also of the University of Oregon, set out to create a set of tested and refined performance indicators that transit agencies across the nation can use to evaluate and improve their system performance in relation to livability goals.

Traditionally, transit systems are thought of exclusively in their wholeness: how the system serves a region,...

'Straphanger' author gives his take on transit systems at Oregon Transportation Summit

Sep 05, 2013

At age 8, Taras Grescoe decided that his Vancouver, B.C., residential street had too many cars chugging past. So he removed them.

“I completely redesigned our city block and modeled with Monopoly hotels what it would look like without cars,” Grescoe said. “I was this 8-year-old urban planning geek in the making.”

While his career took a different path, those early transportation experiences shaped a worldview Grescoe outlines in his latest book, “Straphanger.” Grescoe will present his observations as the keynote speaker for the Oregon Transportation Summit Sept. 16.

The author of nonfiction essays and books including “Bottomfeeder: How to Eat Ethically in a World of Vanishing Seafood” Grescoe is a frequent contributor to the New York Times, the Independent and National Geographic Traveler and has written for Gourmet, Salon and Wired.

Ann Niles lecture series brings world-class transportation speaker to Portland State

Jul 16, 2013

The Ann Niles Transportation Lecture series opens Aug. 26 with a lecture from Jean-François Pronovost of Vélo Québec titled "Growing a World-Class Cycling Culture: Lessons from Québec." The series is sponsored by the Ann Niles Transportation Lecture Endowment and serves as a legacy to Ann Niles, an advocate for livable neighborhoods.

Philip Niles created the endowment with a gift to the Initiative for Bicycle and Pedestrian Innovation, or IBPI, in honor of his late wife. Ann Niles was a strong advocate for livable neighborhoods and served on many transportation-related boards and committees in Portland.

The lecture series keeps alive the spirit of Ann Niles' advocacy. Niles pushed for better sidewalks and crosswalks to make Portland a safe and comfortable place to walk, and for bicycle routes and parking to do the same for bicycling.

"This inaugural Ann Niles Transportation Lecture, and all those that follow, help spread Ann's passion for creating livable neighborhoods to students, practitioners and the greater community," said OTREC Director Jennifer Dill.

The series' first speaker, Pronovost, has helped bring active transportation into the lives of people in communities across Québec. As vice president for development and public affairs for Vélo Québec, he helps develop new projects and partnerships.

OTREC scholar Sirisha Kothuri wins NITC dissertation fellowship

Jun 24, 2013

Sirisha Kothuri, an OTREC scholar for the past two years and a current Ph.D. candidate at Portland State University, has been awarded one of NITC'S 2013 dissertation fellowships.

The $15,000 fellowship -- funded through an ISS (Institute for Sustainable Solutions) grant -- along with an $800 OTREC/NITC scholarship for the 2012-2013 academic year, will assist Kothuri with her research into pedestrian signal timing.

Sirisha was born and raised in Hyderabad, India, and still misses the heat — or at least, the warmth; she has yet to become completely acclimated to Portland, Ore weather. In Hyderabad she obtained a bachelor's degree in Civil Engineering from Osmania University in 1999. She moved to Baton Rouge, Louisiana in 1999 to get a Master’s degree in Civil Engineering at Louisiana State University.

A visit to Illinois for her brother's graduation opened her eyes to the automobile-centric cities that make up much of the United States. She was surprised at some of the infrastructure in the Midwest, which decidedly favors cars over pedestrian and other means of active transport.

PSU planning students re-imagine Lombard Street

May 31, 2013

Each year, Portland State University’s MURP, or Master’s of Urban and Regional Planning, program hosts a public presentation to showcase the work of its graduating master’s students. Students who graduate with a Master’s in Urban and Regional Planning spend the last two terms of their program collaborating on workshop projects, completing planning tasks for local clients or business organizations.

This year’s presentations took place on Wednesday, attended by a crowd of about a hundred PSU students, professors, MURP clients and community members. Six groups presented their projects. Some of the projects were transportation-focused, especially one titled "Lombard Re-Imagined."

Swift Planning Group, composed of members Kathryn Doherty-Chapman, Zef Wagner, Brian Hurley, Jake Warr, Rebecca Hamilton, and Jodi Jacobson-Swartfager, developed a plan to improve Lombard Street, a key transportation corridor in North Portland.

The challenge facing the group had to do with the many roles that Lombard street plays. The street is both an arterial throughway and a state highway. It is an overdimensional freight route, for trucks that are too big to go anywhere else in North Portland, and it has also been designated as a main street in Metro’s 2040 Growth Concept. The various...

Flashing-yellow-arrow research spotlights pedestrian safety risk

Apr 11, 2013

Flashing-yellow-arrow traffic signals offer convenience for drivers by permitting them to turn left after yielding to oncoming traffic. This convenience, OTREC research has found, can come at the expense of safety, especially where the traffic mix includes pedestrians.

OTREC researchers David Hurwitz of Oregon State University and Christopher Monsere of Portland State University examined how driver behaviors affect pedestrian safety at flashing yellow arrows. Their findings show that drivers at these intersections often don’t even look for pedestrians.

This research will be the focus of OTREC’s first live interview-style Webinar May 7. Host Steph Routh of Oregon Walks will interview the researcher-practitioner team, explore real-world applications and take audience questions. The Webinar is free. Details are at this link:

Flashing-yellow-arrow Webinar

Flashing yellow arrows have been replacing other left-turn signals, such as solid green or flashing yellow or red circles, to indicate that drivers may turn after yielding to oncoming traffic. These turns are considered “permissive.” Turns where no conflicting traffic is present, such as those indicated with a green arrow, are “protected” turns. The flashing yellow arrow’s inclusion in the 2009 Manual on Uniform Traffic Control Devices sped up the signal’s adoption to...

Active travelers are competitive customers, research report indicates

Apr 10, 2013

Bicycle commuters represent a significant chunk of business consumers in Portland, Ore., one of America's most bike-friendly cities. OTREC research in the past year has provided data on how cyclists and other mode users patronize local businesses.

The final OTREC research report is available on the project page. Lead researcher Kelly Clifton of Portland State University also presented her findings at the 2013 Oregon Active Transportation Summit in Salem.

The research found that bicycle consumers spend as much money, on average, as those who drive, and that local businesses can make an effort to attract this share of the market. The Plaid Pantry convenience store chain, a participant in the research, subsequently installed bike racks at 12 locations to make them more hospitable to cycling consumers, as first reported in a post on the Bike Portland blog.
