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 …

Bus-Bike Designs For The Division Transit Project, Derek Abe, Jesse Stemmier

PSU Transportation Seminars

This seminar is brought to you by the Oregon chapter of the Association of Pedestrian and Bicycle Professionals (APBP), with support from TREC at Portland State.

Transit stops and stations are a confluence of complementary and competing activities - pedestrians accessing businesses, passengers boarding and alighting, and bicyclists zipping through to their destinations. People are moving in different directions, at different speeds, and need to be able to navigate this space safely and comfortably. A common point of conflict is the bus/bicycle interaction when a transit stop is adjacent to a bike lane. Designs for integrating pedestrian and bicycle …

Making The Seemingly Impossible Project Real Through Local Improvement Districts, Andrew H. Aebi

PSU Transportation Seminars

The planning process identifies community needs but often needs the creative use of financial leverage to make those projects a reality on the ground. Timing is important on Local Improvement District (LIDs), and the window of opportunity is often short.

For Portland's Bureau of Transportation, managing the public's desire for streets in good condition with room to walk and bike safely and accommodating freight movement and population growth can be a tall order. Add in the need to work with water, sewer and underground utilities, and things get complicated.

When needs exceed resources, smart strategies can help fill the gap. …

Deriving Lane-Level Insight From Gps Data: Innovations For Traffic & Autonomous Driving, James Fowe

PSU Transportation Seminars

With the on-going disruption of the transportation industry and rapid advancement in ITS technologies; emerging smart cities, navigation systems and autonomous transportation, the need for highly accurate geospatial localization has never been more crucial. These technologies demand that we have more granular location information of vehicles not just on a road, but to a specific lane on the road.

This presentation will give a pedagogical style summary and overview of some of the on-going research work at HERE Technologies and how we have pushed the state-of-the-art in lane-localization of noisy GPS probe data using novel Machine Learning Algorithms and how …

Webinar: E-Bikes For Everyone: Electrifying Communities In New Ways, John Macarthur, Sergio Lopez

TREC Webinar Series

Electric bicycle (e-bike) use is a rising phenomenon in North America. In 2018, John MacArthur of Portland State University conducted a national survey to understand issues facing e-bike owners. Reducing physical exertion, conquering challenging topography and replacing car trips are a few of the most important reasons for buying an e-bike. The electric assist of the e-bike helps to generate more trips, longer trips and different types of bicycle trips. Through analysis it also became evident that e-bikes are making it possible for more people to ride a bicycle, many of whom are incapable of riding a standard bicycle or …

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 …

Exploring The Determinants Of Vulnerable Road Users’ Crash Severity In State Roads, Álvaro Caviedes

PSU Transportation Seminars

Part of the Student Presentations from TRB

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. The results seem to suggest that besides improvements …

Measuring Stress Levels For Real-World On-Road Cyclists: Do Bicycle Facilities, Intersections And Traffic Levels Affect Cyclists' Stress?, Álvaro Caviedes

PSU Transportation Seminars

This research effort presents a novel approach to measure cyclists’ stress: real-world, on-road measurements of physiological stress as cyclists travel across different types of bicycle facilities in various traffic volumes. This study addresses the question of how the characteristics of a bicycle trip affect stress levels using physiological data, specifically GSR. As detailed in the next section, GSR-based studies have been successfully employed for many years in the psychological field to recognize and associate emotions and behaviors to physiological responses. The three research questions examined in this study are: i) Does peak traffic impact cyclists’ stress levels? ii) Do intersections …

Evaluating The Level-Of-Service Of Protected Bike Lanes, Nick Foster

PSU Transportation Seminars

Summary: The most recent edition of the Highway Capacity Manual (HCM) contains analysis procedures for measuring the level-of-service (LOS), also referred to as quality of service, provided by an urban roadway to bicyclists. The method uses different design and operating features of the roadway segment (e.g. width, motor vehicle volumes and speeds) to assess an LOS grade of A (best) to F (worst). These procedures are used by planners and engineers to recommend how existing streets could be retrofitted or new streets designed to better serve people on bicycles (and other modes). However, the current HCM does not include methods …
