China's Motorization Wave And The Place Of Emerging Technologies, Christopher Cherry

PSU Transportation Seminars

E-bikes, E-Cars, Carshare, Bikeshare, and Micro-EVs in China have shaken up the traditional motorization pathways that have occurred in developing countries in the past. The combination of emerging vehicle technologies, urban and environmental constraints, and heavy-handed policy make China's motorization processes unique in the world—but how China motorizes has far-reaching impacts based on sheer volume of vehicles and population.

This seminar discusses the results of a six-year NSF CAREER project to explore China's motorization processes, combining behavioral and environmental modeling approaches to assess the impacts of emerging vehicle technologies on motorization and ultimately environmental sustainability. The focus is mostly on …

Revolutionary changes have occurred in the communication landscape, and there has been a rapid diffusion of social media use as a means of communicating transit information to the public. Significant resources are being directed to the use of social media in communication, yet little effort exists that measures the impacts of these popular vehicles of communication. Rarely studied is the role …

Towards Systematic Prediction Of Urban Heat Islands: Grounding Measurements, Assessing Modeling Techniques, Jackson Voelkel, Vivek Shandas

Urban Studies and Planning Faculty Publications and Presentations

While there exists extensive assessment of urban heat, we observe myriad methods for describing thermal distribution, factors that mediate temperatures, and potential impacts on urban populations. In addition, the limited spatial and temporal resolution of satellite-derived heat measurements may limit the capacity of decision makers to take effective actions for reducing mortalities in vulnerable populations whose locations require highly-refined measurements. Needed are high resolution spatial and temporal information for urban heat. In this study, we ask three questions: (1) how do urban heat islands vary throughout the day? (2) what statistical methods best explain the presence of temperatures at sub-meter …

Metro, Portland's regional governing agency, conducts annual two-hour counts along its regional trail every September. This upcoming fall (2017) will be the 10th year that the counts have been held, which means we at Metro can finally start seeing noticeable, long-lasting trends in the regional trail network. Perhaps more importantly, we are seeing how these data have directly impacted investments in future trail, bicycle, and pedestrian projects.

This seminar will cover the history of the program, details of how it's conducted and why it's conducted that way, how data are used (including an inside look at future iterations of Metro's …

Webinar: Developing Practical Dynamic Evaluation Methods For Transportation Structures, Charles Riley

TREC Webinar Series

Deteriorating transportation infrastructure is constantly in the news. Government agencies at all levels are pursuing methods to monitor structural health, so that they can prioritize repairs. In Oregon, the Cascadia Subduction Zone megathrust earthquake looms as a significant natural hazard for which our transportation network is ill-prepared. The Oregon Department of Transportation (ODOT) estimates that it will take around $2.6 billion over seven years to repair or replace many of the existing bridges in the state’s network to maintain lifeline routes after a Cascadia event. Funding for the scenarios envisioned by ODOT is not forthcoming, and the project …

Peer-To-Peer Carsharing: Short-Term Effects On Travel Behavior In Portland, Or, Jennifer Dill, Nathan Mcneil, Steven Howland

TREC Final Reports

Peer-to-peer (P2P) carsharing is a relatively new concept in the U.S. Enabled by recent internet and mobile technology development, P2P carsharing generally involves a facilitating company connecting private vehicle owners to people who are interested in renting a vehicle. P2P carsharing has many things in common with business-to-consumer (B2C) carsharing services. Consumers join the service to rent vehicles on a short-term basis from locations dispersed throughout a certain area. Both services may allow households to reduce their private car ownership. However, P2P carsharing differs substantially from other models in that there are two distinct sets of consumers: those who rent …

Narratives Of Marginalized Cyclists: Understanding Obstacles To Utilitarian Cycling Among Women And Minorities In Portland, Or, Amy Lubitow

TREC Final Reports

Research has demonstrated that everyday or utilitarian forms of cycling are most likely to generate positive population-level health impacts (Garrard et al., 2012), yet significant deterrents to routine cycling remain, particularly for women and minorities. The primary aim of this project was to conduct a qualitative interview study that generated rich, narrative data regarding obstacles to routine or utilitarian cycling for women and minorities who already see biking as a viable form of transit, but who make relatively few bike trips. A secondary aim of the project was to develop a set of specific interventions that have the potential to …

Breaking Barriers To Bike Share: Insights On Equity From A Survey Of Bike Share System Owners And Operators, Steven Howland, Nathan Mcneil, Joseph Broach, Kenneth Rankins, John Macarthur, Jennifer Dill

The number of public bike share systems has been increasing rapidly across the United States over the past five to 10 years. To date, most academic research around bike share in the U.S. has focused on the logistics of planning and operationalizing successful systems. Investigations of system users and impacts on the local community are less common, and studies focused on efforts to engage underserved communities in bike share are rarer still. This report uses a survey of representatives from 56 U.S. bike share systems to better understand and document current approaches toward serving low-income and minority populations. The survey …

Bike-Ped Portal: Development Of An Online Nonmotorized Traffic Count Archive, Krista Nordback, Kristin A. Tufte, Nathan Mcneil, Morgan Harvey, Michelle Watkins

TREC Final Reports

Robust bicycle and pedestrian data on a national scale would serve numerous purposes. Access to a centralized nonmotorized traffic count archive can open the door for innovation through research, design and planning; provide safety researchers with a measure of exposure; provide fundamental performance metrics for planning and funding decisions; and allow policymakers and transportation professionals to better support the public’s desire for livable communities. Numerous jurisdictions have initiated nonmotorized traffic count programs. However, many agencies and policymakers, who need data to support investment decisions, are in locations without a centralized count program. This lack of access to count data may …

Barriers To Biking For Women And Minorities, Amy Lubitow

TREC Project Briefs

The health benefits of bicycling are well understood; numerous studies link increased cycling activity with improved health outcomes. Research suggest that the cycling behavior most likely to generate broad, population-level health benefits is everyday routine cycling—including running errands and taking other short trips. Despite these health benefits and new investment in cycling infrastructure, overall cycling levels in the U.S. lag behind many other nations. Amidst findings of increased ridership, research still finds that women and racial minorities are underrepresented as cyclists in North America.

While quantitative data may reveal estimates of these disparities, little is known about the motivations or …
