Pedestrian Safety And Social Equity In Oregon, Josh Roll, Nathan Mcneil

PSU Transportation Seminars

Past research and planning has highlighted the existence of pedestrian injury disparities throughout the US and some local agencies have performed cursory analysis in Oregon. However, no statewide analysis of pedestrian injuries in Oregon has been completed to see how these injury outcomes differ by race and income.

This presentation aims to help better understand the factors that result in disparate pedestrian injury outcomes for different sociodemographic groups. This research uses data from a variety of sources to understand pedestrian injuries by social equity measures including income, poverty, race, ethnicity, disability and English proficiency. The authors conclude that Black, Indigenous …

Biking And Walking Quality Counts: Using “Bikeped Portal” Counts To Developdata Quality Checks, Nathan Mcneil, Kristin Tufte

TREC Final Reports

Cycling and walking are sustainable modes of transportation which improve community livability, but these modes have not been studied with the quantitative rigor applied to motor vehicle travel. This work aims to change that by improving bicycle and pedestrian traffic monitoring data quality, including how erroneous data can most accurately and efficiently be identified through automated processes. The research approach analyzes continuous bicycle and pedestrian count data stored in BikePed Portal, a data archive of bicycle and pedestrian count data. A primary goal of the project is to explore tests that could help to identify aberrant and/or erroneous data. A …

Pedpdx: Addressing Equity Through Citywide Pedestrian Planning, Michelle Marx, Francesca Patricolo

PSU Transportation Seminars

Pedestrian safety and access is an equity issue. In Portland, inadequate pedestrian infrastructure and traffic safety concerns disproportionately impact low-income communities and people of color. The City is attempting to rectify these inequities through PedPDX, Portland’s new citywide pedestrian plan (anticipated for adoption in Spring 2019). PedPDX prioritizes sidewalk and crossing improvements and other investments, policies, strategies and tools to make walking safer and more comfortable across the city.

Come learn about the strategies PedPDX is using to address transportation equity in Portland, including establishing a data-based prioritization for citywide pedestrian investments, identifying roadway and behavioral characteristics most closely …

New Pedestrian Modeling Tools: Growing Beyond The Portland Region, Kelly Clifton, Jamie Orrego-Onate, Patrick Allen Singleton, Robert J. Schneider

TREC Project Briefs

This project focuses on making our measures, models, and methods more transferable to other locations. Specifically, we re-evaluate, compare and test our pedestrian index of the environment (PIE) measure using data resources more commonly available to planning agencies across the country. Next, we test the results of PIE and its input data in models of pedestrian mode choice for stability of estimation results within a region (intraregional) and between regions (interregional). This research is the next logical step in the MoPeD’s enhancement and is critical to enabling its utility beyond the Portland region. The results of this project show that …

Webinar: Rethinking Streets For Bikes: An Evidence Based Guide Of Bike-Friendly Street Retrofits, Marc Schlossberg, Roger Lindgren

TREC Webinar Series

There is a growing demand for better infrastructure and fewer barriers to biking and other forms of space-efficient micromobility. Tackling daily trips by bike is easier on the environment, healthier for users and non-users alike, uses precious urbanized public and private land more efficiently, costs taxpayers less to build and maintain infrastructure, and when routes are safe and comfortable, moving by bike is also fun! Complete Streets policies are being adopted across the country, and there is an active conversation around the safety imperative of a Complete Streets approach. Yet, local officials often need both design guidance and the …

Are Wide Streets Negligent?, Michael Lewyn

Scholarly Works

American commercial streets are typically designed to encourage rapid automobile traffic, thus making streets unsafe for pedestrians. In the 2016 case of Turturro v. City of New York, the New York Court of Appeals upheld a jury verdict against a city for failing to slow down such traffic. This article describes Turturro, but shows how limited its holding was: the Turturro court emphasized a city's failure to study traffic calming, so if a city studies its options adequately it can avoid liability even if its policies are unsuccessful.

Exploring The Determinants Of Vulnerable Road Users' Crash Severity In State Roads, Àlvaro Alfonso Caviedes Cómbita

Dissertations and Theses

Pedestrians and bicyclists are the most vulnerable road users and suffer the most severe consequences when crashes take place. An extensive literature is available for crash severity in terms of driver safety, but fewer studies have explored non-motorized users' crash severity. Furthermore, most research efforts have examined pedestrian and bicyclist crash severity in urban areas. This study focuses on state roads (mostly outside major urban areas) and aims to identify contributing risk factors of fatal and severe crashes involving pedestrians and bicyclists in state roads. Two ordinal regression models were developed (one for pedestrian and the other for bicyclist crashes) …

Webinar: Land Use Mix And Pedestrian Travel Behavior: Advancements In Conceptualization And Measurement, Steven R. Gehrke

TREC Webinar Series

Smart growth policies have often emphasized the importance of land use mix as an intervention beholding of lasting urban planning and public health benefits. Past transportation-land use research has identified potential efficiency gains achieved by mixed-use neighborhoods and the subsequent shortening of trip lengths; whereas, public health research has accredited increased land use mixing as an effective policy for facilitating greater physical activity.

However, despite the celebrated transportation, land use, and health benefits of improved land use mixing and the extent of topical attention, no consensus has been reached regarding the conceptualization and measurement of this key smart growth principle …

Webinar: Economic Impacts From Bicycle And Pedestrian Street Improvements, Jenny H. Liu

TREC Webinar Series

As many cities are investing in street improvements to provide better biking and walking experiences, the economic value and impacts of these active transportation facilities remain areas where many practitioners, planners and policy makers are seeking more conclusive evidence. With various modes competing for scarce resources, planners and transportation agencies often struggle with how to justify infrastructure investments for non-motorized modes, particularly when driving is still the predominant mode of transportation in most cities.

In this project we assess property value impacts of Portland’s “Green Loop” signature bike infrastructure concept, illustrating the importance of considering both accessibility and extensiveness of …

Webinar: Improving Walkability At Signalized Intersections With Signal Control Strategies, Edward J. Smaglik, Sirisha Murthy Kothuri

TREC Webinar Series

The goal of signal timing at an intersection should be to maximize efficiency for all users. In many jurisdictions, however, traffic signals are timed mostly with the goal of reducing vehicular delay.

Other road users, such as pedestrians, deserve similar focus. In legacy transportation systems, pedestrians experience delays much in excess of those that would be deemed acceptable for a motor vehicle at the same location.

Excessive delay can lead to pedestrian frustration, non-compliance and ultimately decreased safety.

In the North American context, implementation of strategies to address pedestrian service varies greatly across jurisdictions, and there has been limited research …

Lessons From The Development Of A Guidebook On Pedestrian And Bicycle Connections To Transit, Nathan Mcneil, Allison Boyce Duncan, Drew Devitis

PSU Transportation Seminars

To improve safety and increase transit use, transit agencies and the jurisdictions they serve have to approach transit service as door-to-door not just stop-to-stop.

Walking and bicycling are key modes for transit access.

Working with the Federal Transit Administration, a team from Portland State University developed a guidebook on improving pedestrian and bicycle access to transit (forthcoming). As part of the guidebook process, the PSU team conducted case studies on best practices of recent efforts in Minneapolis, Los Angeles and Atlanta.

This presentation will cover key lessons from the case studies, along with an overview of the guidebook.

Webinar: Development Of A Pedestrian Demand Estimation Tool, Kelly Clifton

TREC Webinar Series

Why model pedestrians?

A new predictive tool for estimating pedestrian demand has potential applications for improving walkability. By forecasting the number, location and characteristics of walking trips, this tool allows for policy-sensitive mode shifts away from automobile travel.

There is growing support to improve the quality of the walking environment and make investments to promote pedestrian travel. Despite this interest and need, current forecasting tools, particularly regional travel demand models, often fall short. To address this gap, Oregon Metro and NITC researcher Kelly Clifton worked together to develop this pedestrian demand estimation tool which can allow planners to allocate infrastructure …

Panic That Spreads Sociobehavioral Contagion In Pedestrian Evacuations, Terra Elzie, Erika Frydenlund, Andrew J. Collins, R. Michael Robinson

VMASC Publications

Crowds are a part of everyday public life, from stadiums and arenas to school hallways. Occasionally, pushing within the crowd spontaneously escalates to crushing behavior, resulting in injuries and even death. The rarity and unpredictability of these incidents provides few options to collect data for research on the prediction and prevention of hazardous emergent behaviors in crowds. This study takes a close look at the way states of agitation, such as panic, can spread through crowds. Group composition—mainly family groups composed of members with differing mobility levels—plays an important role in the spread of agitation through the crowd, ultimately affecting …

Development Of A Pedestrian Demand Estimation Tool: A Destination Choice Model, Christopher D. Muhs

PSU Transportation Seminars

There is growing support for improvements to the quality of the walking environment, including more investments to promote pedestrian travel. Planners, engineers, and others seek improved tools to estimate pedestrian demand that are sensitive to environmental and demographic factors at the appropriate scale in order to aid policy-relevant issues like air quality, public health, and smart allocation of infrastructure and other resources. Further, in the travel demand forecasting realm, tools of this kind are difficult to implement due to the use of spatial scales of analysis that are oriented towards motorized modes, vast data requirements, and computer processing limitations.
