Evaluating Driver and Pedestrian Behaviors at Enhanced Multilane Midblock Pedestrian Crossings: Case Study in Portland, Oregon This study examines driver and pedestrian behaviors at two enhanced midblock pedestrian crossings in Portland, Oregon. One crossing is on a five-lane arterial with a posted speed of 35/45 miles-per-hour (MPH) and features six rectangular rapid flash beacon (RRFB) assemblies and a narrow median refuge. The other crossing is on a suburban arterial with four travel lanes and a two-way left-turn lane. The crossing is enhanced with four RRFB assemblies and a median island with a “Z” crossing, or Danish offset, designed to encourage pedestrians to face oncoming traffic before completing the second stage of their crossing. Approximately 62 hours of video have been collected at the two locations. A total of 351 pedestrian crossings are analyzed for driver compliance (yielding) rates, pedestrian...
Read moreSteve Szigethy and Jamison Kelleher, a team of graduate students in PSU's Master of Urban and Regional Planning program, will present their Planning Workshop project entitled "Imagine 82nd." The project engaged residents, businesses, property owners and students along NE 82nd Avenue in Portland to develop a comprehensive vision for the future of the corridor. Imagine 82nd deals with the portion of 82nd Avenue between the Banfield Expressway and NE Sandy Boulevard, 1.3 miles in length. This particular stretch is home to many retail and service businesses that typify the rest of 82nd Avenue, but it also includes Madison High School, a major corporate headquarters, and a 20-acre vacant brownfield site. At this seminar, Steve Szigethy and Jamison Kelleher will present the vision concepts they developed with the community, with particular emphasis on transportation and land use components.
The video begins at 5:54.

Shared electric scooters (e-scooters) are fast becoming a mobility option in cities across the United States. This new micromobility mode has the potential to replace car usage for certain trips, which stands to have a positive impact on public health and sustainability goals. However, many aspects of this emerging mode are not well understood.This webinar explores the findings of three NITC studies examining transportation mode choices, safety, and public health outcomes of electric scooters.

Identification and Characterization of PM2.5 and VOC Hot Spots on Arterial Corridor by Integrating Probe Vehicle, Traffic, and Land Use Data: The purpose of this study is to explore the use of integrated probe vehicle, traffic and land use data to identify and characterize fine particulate matter (PM2.5) and volatile organic compound (VOC) hot spot locations on urban arterial corridors. An emission hot spot is defined as a fixed location along a corridor in which the mean pollutant concentrations are consistently above the 85th percentile of pollutant concentrations when considering all other locations along the corridor during the same time period. In order to collect data for this study, an electric vehicle was equipped with instruments designed to measure PM2.5 and VOC concentrations. Second-by-second measurements were performed for each pollutant from both the right and left sides of the vehicle. Detailed meteorological, traffic and land use data is also...
How do people with intersecting marginal identities experience social exclusion as they travel via mass transit?
To answer this question, PSU researchers employed a qualitative method less common in transportation studies: photovoice. Researchers asked participants to describe the factors that shape their travel behavior and provide photographic data of their experiences. Then, they conducted in-depth video interviews to gain further depth and clarity regarding the visual data.
The findings from this study can help transit system designers better understand how experiences of harassment and discrimination across the entire users’ journey affects the riders’ decisions about whether and when to take transit, and the extent to which transit-related infrastructure is related to decisions about where to live or their access to long-term housing.
