Webinar: Integrating Explicit And Implicit Methods In Travel Behavior Research: A Study Of Driver Attitudes And Bias, Tara Goddard

TREC Webinar Series

Car crashes are still a leading cause of death in the United States, with vulnerable road users like bicyclists and pedestrians being injured or killed at rates that outpace their mode share.

Planners, engineers, and advocates are increasingly adopting Vision Zero and Tactical Urbanism approaches and trying to better understand the underlying causes of dangerous roadway interactions. However, existing research into crash causation has focused on instrumental factors (e.g. intersection type, vehicle speed) while little research has probed the role of attitudes or socio-cognitive mechanisms in interactions between roadway users.

Social psychology suggests that attitudes and social cognitions can play …

Examining The Right To Bicycle: Synergies And Tensions Between Human Rights, Civil Rights, And Planning For Cycling, Aaron Golub

PSU Transportation Seminars

Securing and expanding the broad right to bicycle, including the right to adequate and safe street space and related infrastructure for cycling along with other policies and protections for cyclists, is the obvious goal of cycling advocacy efforts in their various forms. All rights are situated within frameworks for promulgating and insuring they are honored, and the right to cycling is no different. This project investigates how the right to bicycle falls within various rights frameworks, focusing on broad human rights and civil rights frameworks while reflecting as well on traffic safety codes and transportation planning frameworks. While certain aspects …

Influence Of Road Cross Section On Access Spacing, Karen K. Dixon, Yanfen Zhou, J. L. Gattis

TREC Final Reports

This report presents a study on the influences of select cross-sectional-related design elements (specifically median configurations and bicycle lanes) and their impact on crash severity and type, as well as the associated driver gap acceptance for turning maneuvers at midblock driveway locations on urban arterials. The primary goal of this proposed research is to better understand how the median and bicycle lane configurations can influence safety and operations at driveway locations. The research team utilized crash data, traffic data, and roadway information from driveway locations in the U.S. states of Oregon, Arkansas and Oklahoma. The project team supplemented the data …

Contesting The North Williams Traffic Operations And Safety Project, Amy Lubitow, Thaddeus R. Miller

Urban Studies and Planning Faculty Publications and Presentations

The North Williams Traffic Safety Operations Project, overseen by the Portland Bureau of Transportation (PBOT), was proposed in 2010. With an initial budget of $370,000, the project was designed to reduce conflict between buses, bicycles and motor vehicles on North Williams Avenue and improve the overall safety and accessibility of the street. As is common practice, PBOT’s first step in this project was to organize a stakeholder advisory committee (SAC) of interested business owners, neighborhood association representatives, residents, and key stakeholders living or working along North Williams Avenue who would be tasked with advising the city on the project. However, …

Evaluation Of Innovative Bicycle Facilities: Sw Broadway Cycle Track And Sw Stark/Oak Street Buffered Bike Lanes, Christopher Michael Monsere, Nathan Mcneil, Jennifer Dill

Urban Studies and Planning Faculty Publications and Presentations

Two innovative bicycle facilities installed in late summer and early fall 2009 in downtown Portland by the City of Portland Bureau of Transportation (PBOT) were evaluated to understand how they are functioning on multiple levels. All of these facilities involved removing a motor vehicle lane by restriping to provide additional roadway space to bicyclists. The facilities include:

• A cycle track (a seven-foot bike lane separated from motor vehicle traffic by a row of parked cars and a painted three-foot pedestrian buffer), on SW Broadway from SW Clay to SW Jackson through the Portland State University campus, and
• A couplet of …

Ibpi: Bicycle And Pedestrian Education Program, Jennifer Dill, Lynn Weigand, Karen Dixon

Urban Studies and Planning Faculty Publications and Presentations

Since the 1990s, the amount of attention and funding for bicycle and pedestrian infrastructure has increased significantly. This, combined with the role of transportation in public health and environmental concerns, has raised expectations for engineering and planning practitioners to possess more knowledge and skills related to pedestrian and bicycle planning and design. This demand requires more education around these topics but university curriculum doesn?t reflect these important shifts in the field. This project was intended to begin addressing the need for more bicycle and pedestrian curriculum in two ways: (1) Determine the existence of and need for courses and curriculum …
