Friday Transportation Seminar: PSU Student Research from the TRB 2022 Annual Meeting

Friday, January 21, 2022, 11:30am to 12:30pm PST

Friday Transportation Seminars at Portland State University have been a tradition since 2000. You can join us online at 11:30 AM. Stay tuned for an announcement of the fall term lineup.

THE TOPIC

Join us for a two-part seminar diving into research that was presented by Portland State University students at the annual meeting of the Transportation Research Board (TRB) in January 2022.

FIRST PRESENTATION

Webinar: Mobility, Accessibility, and Resiliency of Community-Dwelling Older Adults

Wednesday, January 26, 2022, 11:00am to 12:00pm PST

OVERVIEW

Mobility disparities among older adults affect their ability to travel and access services. This project seeks to understand challenges, barriers, and gaps that older adults experience and to develop forms of assistance or educational strategies to fill the varying mobility gaps and meet the mobility needs. This study characterizes older adults’ use of existing and potential transportation options, including conventional transit, paratransit, and ride-hailing systems, based on surveys and interviews collected from community-dwelling older adults in Dallas, Texas. Through the interview during the pandemic, the research team found that perceptual and knowledge barriers appear to be reduced among older adults to adopt new mobility options such as ride-hailing although financial and technology barriers still exist. Based on the findings, we discussed several strategies that can potentially reduce observed barriers and challenges and enhance mobility to ultimately increase social equity across transportation-disadvantaged populations, particularly among low-income older adults.

KEY LEARNING OUTCOMES

  • The audience will evaluate older adults’ actual usages, awareness, willingness to utilize, and any associated challenges and barriers to access available transportation options.
  • The audience will identify factors enhancing resilience among marginalized older adults during the COVID-19 pandemic....

Webinar: Is Transit-Oriented Development Affordable for Low and Moderate Income Households?

Tuesday, February 15, 2022, 10:00am to 11:00am PST

OVERVIEW

The transportation and land use planning paradigm is shifting away from segregated uses connected by highways and roads to more compact, mixed-use developments connected by high quality transit. This new paradigm has brought transit-oriented development (TOD) to the fore, and researchers continue to highlight advantages of this style of well-integrated land use and transportation planning. When it comes to affordability, what counts isn’t housing costs alone but the combination of housing plus transportation costs (H+T).  If TODs do, in fact, command higher rents due to increased transit accessibility, this creates an issue of social equity, especially if higher housing costs are not offset by transportation-related cost savings. Promoting a development style that limits access for transit-dependent populations by pricing those residents out of the market could potentially be counterproductive. In this study we first confirm whether TOD style development capitalizes on increased accessibility by demanding higher rents than comparable contemporary developments with similar amenities. More importantly, we then compare the rent premiums with estimates of transportation cost savings for TOD dwellers to see whether the combination of H+T exceeds affordability standards for different income groups. Based on case studies, we also identify measures taken by exemplary TOD developers and jurisdictions to make housing...

Transportation Data Webinar: Video-Image Processing Technology for Bikes and Pedestrians

Wednesday, February 16, 2022, 2:00pm to 3:00pm PST

OVERVIEW

Join us for a two-part seminar looking at video-image processing technology for bicyclists and pedestrians.

FIRST PRESENTATION
Bicyclist Distinguishment at Traffic Signals Using Infrared Camera Techology

Shaun Quayle of Washington County, Oregon and Chase Hildner of DKS Associates

The speakers will summarize the goals and evaluation results of Washington County, Oregon's pilot project efforts to leverage infrared video cameras to distinguish bikes on approach at signalized intersections. They will also touch on the signal phasing and timing applications to be employed.

Key Learning Outcomes

  • Understanding of the problem cyclists often face at signalized intersections with legacy detection systems.
  • Results of Washington County's efforts to determine the accuracy of detection systems on distinguishing bicyclists from other roadway users.
  • Awareness of the signal timing applications to enhance cyclist safety.

SECOND PRESENTATION
Ped Counts - A Case Study of Clark County
Subhadipto Poddar of Clark County, Washington

With emerging video detection technologies, traffic detection has seen...

Webinar: Exploring Data Fusion Techniques to Derive Bicycle Volumes on a Network

Thursday, March 10, 2022, 11:00am to 12:00pm PST

OVERVIEW

Planners and decision makers have increasingly voiced a need for network-wide estimates of bicycling activity. Such volume estimates have for decades informed motorized planning and analysis but have only recently become feasible for non-motorized travel modes. Recently, new sources of bicycling activity data have emerged. These derive primarily from GPS-based smartphone apps (e.g. Strava, Ride Report, Map My Ride) and GPS-enabled public bicycle sharing systems. These emerging data sources have potential advantages as a complement to traditional count data, and have even been proposed as replacements for such data, since they are collected continuously and for larger portions of local bicycle networks. However, the representativeness of these new data sources has been questioned, and their suitability for producing bicycle volume estimates has yet to be rigorously explored. This project develops a method for evaluating and integrating emerging sources of bicycle activity data with conventional demand data and methods, and applies the results to several locations to predict network-wide bicycle volumes.

THE RESEARCH

This webinar is based on a study funded by the National Institute for Transportation and Communities (NITC) and conducted at Portland State University and the University of Texas at Arlington. The project is supported by a pooled fund grant. Matched by NITC, funding partners include Oregon Department of...
