AASHTO places bike signals project in Sweet Sixteen

Jun 29, 2015

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...

PSU doctoral student honored as top Eisenhower Fellow at TRB

Jan 12, 2015

In a morning workshop on Sunday at TRB's annual meeting, Patrick Singleton of Portland State University was named the top-ranked Eisenhower Fellowship recipient

The session featured innovative research from second- and third-year Eisenhower doctoral fellowship recipients from top universities across the nation.

Singleton was one of four civil and environmental engineering students from PSU to be awarded the Dwight David Eisenhower Transportation Fellowship in 2014.

The paper he presented, "The theory of travel decision-making: A conceptual framework of active travel behavior," integrates theories from economics, geography and psychology to arrive at a unifying framework for understanding and predicting active travel decisions.

It examines the thought processes behind individuals' short-term travel decisions and explains the roles of activities, built environment factors, socio-demographics, perceptions, and habit in influencing those decisions.

Singleton's award marks the second year in a row that a Portland State student has taken the top honor, following Kristina Currans.

Singleton's adviser, Prof. Kelly Clifton, said she's proud of his accomplishment and the continued achievement of Portland State students. "It shows the strength of the program," Clifton said.

WTS scholarships awarded to three students at NITC campuses

Workshop participants will cycle down Portland’s best trails

Sep 29, 2014

The Initiative for Bicycle and Pedestrian Innovation (IBPI) is teaming up with Alta Planning + Design to offer a firsthand, on-the-ground training opportunity at the end of October.

They will teach a trail design course at Portland State University, with field tours of some of Portland's biggest trail challenges and best solutions.

Course instructors are Alta associates Robin Wilcox, George Hudson, and Karen Vitkay. They will share their experience and provide examples from some of the best trails around the country.

Multi-use trails, not accessible by car but meant to be shared by pedestrians, cyclists and the occasional leashed dog, are pleasant routes by almost anyone’s standards. Often winding through wooded areas or along waterways, insulated from the noise of traffic and offering contact with nature, they present an attractive alternative to cyclists who are not as comfortable riding on busy streets.

While any segment of trail can offer a pleasant stroll, the true beauty of shared-use trails lies in being able to use them: as an alternate, off-street means of travel, a route to school or a way to get to work in the morning. A widespread switch from driving on streets to...

E-Bike laws create widely differing situations for users

Aug 28, 2014

In 2009, researchers at the Massachusetts Institute of Technology (MIT) developed the Copenhagen Wheel, a device that converts an ordinary bicycle into a hybrid e-bike.

An e-bike is considered a motorized bicycle under Massachusetts law. This means that once the 13-pound, 26-inch Copenhagen Wheel is attached to the rear wheel of a bicycle, the resulting vehicle requires a driver’s license to operate, must be registered with the DMV, and its rider must wear, not just a bike helmet, but a motorcycle helmet to be in compliance with the law.

Electric bicycles, or e-bikes, are well established in China and other Asian and European countries but market adoption has been slow in the United States.

Part of the reason could be that the law is often nebulous where e-bikes are concerned.

NITC researchers at Portland State University conducted a policy review revealing the current state of legislation regarding e-bikes in the United States and Canada.

The report, Regulations of E-Bikes in North America, provides a summary of legal definitions and requirements surrounding the use of electric-assist bicycles in each of the 50 states, Washington D.C. and 13 Canadian provinces.

No two jurisdictions are exactly alike in their legal treatment of this relatively new mode...

PSU students help determine Cully neighborhood's walkability needs

Jul 11, 2014

Three Portland State University graduate students in the Nohad A. Toulan School of Urban Studies and Planning used GIS technology to collect and analyze residents’ thoughts about walkability needs for Portland, Oregon’s northeast Cully neighborhood.

Their report, Engaging Cully, was the final product of a ten-week course called Public Participation Geographic Information Systems (PPGIS), taught by PSU professor Vivek Shandas.

In PPGIS, community input is used to create GIS-based data and diagnostics maps which can inform planners’ decision-making process. Team members Travis Driessen, Brandi Campbell and Eduardo Montejo worked with community-based organizations and residents to assess the needs of the Cully neighborhood’s pedestrian network using PPGIS methods.

Prior to this project, Driessen, who is working toward a graduate certificate in Geographic Information Systems at PSU, was already collaborating with David Hampsten, a board member of the Hazelwood Neighborhood Association and member of the East Portland Action Plan, to help Prioritize Portland! – a coalition consisting of multiple organizations including the ...

Emerging field of HIA helps to assess the public health impact of future plans

Jul 11, 2014

New research from NITC looks at Health Impact Assessment, or HIA, in transportation planning.

The leading causes of death in the United States are no longer communicable diseases. Instead, chronic conditions linked to behaviors and shaped by environments—such as obesity and diabetes—are today’s most pressing public health concerns.

HIA is a way of evaluating the effects that planning decisions will have on public health.

Researcher Nicole Iroz-Elardo studied this relatively new endeavor, analyzing and comparing three contemporary case studies in HIA.

She will share her findings in an IBPI webinar on July 16, 2014.

By engaging professionals from multiple disciplines, HIA can give planners a larger knowledge base to inform decisions.

In a collaborative process that did not emerge in the U.S. until 1999, stakeholders and community members engage with public health professionals to identify and deliberate about health interests related to the proposed plan.

They generally focus on health equity, and use as a framework the social determinants of health: a broad...

OTREC research examines ways to anonymize location data

Jul 07, 2014

A new OTREC report explores an innovative technique for making household travel data more widely available without compromising individual privacy.

Public agencies spend vast amounts of money collecting information in household travel surveys.

In the report, Wider Dissemination of Household Travel Survey Data Using Geographical Perturbation Methods, lead investigator Kelly Clifton of Portland State University examines ways to make that information more accessible by planners and other professionals.

Survey respondents are guaranteed anonymity in exchange for their participation. In addition to asking which modes individuals use to get around, surveys learn where they live, where they work, their household sizes and demographic information.

Detailed geospatial referencing of the home, work and other travel destinations is common practice.

Such data can be of enormous use to planning professionals, but its dissemination must be balanced with the need to keep locations confidential.

To protect this confidentiality, data are often aggregated to a geographic level such as census tracts or transportation analysis zones (TAZs) before being publicly shared....
