Webinar: Mobility, Accessibility, and Resiliency of Community-Dwelling Older Adults
Wednesday, January 26, 2022, 11:00am to 12:00pm PST
PRESENTATION ARCHIVE
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...

Transportation Data Webinar: Current Landscape of Probe Data and a Look into Vendors Providing Access
Wednesday, December 15, 2021, 2:00pm to 3:00pm PST
PRESENTATION ARCHIVE
OVERVIEW
With so many Probe-Data Vendors in the market, and the fact that each offers their own unique solutions, it can be challenging to identify which vendor(s) would best meet the needs of an organization. Based on a study prepared for the Seattle Department of Transportation, this presentation will provide highlights around eight Probe-Data Vendors and their capabilities, limitations, and quality of data.
KEY LEARNING OUTCOMES
- An understanding of primary vendors that offer probe data and related products
- Key probe data sources used to put together data summaries
- An understanding of the types of platforms that exist and basic analytical capabilities
- Data quality considerations from each of the vendors offering probe data

Friday, November 19, 2021, 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.
PRESENTATION ARCHIVE
THE TOPIC
The urban freight system is essential for the livability of any city. In the last decade, densification, the growth of e-commerce, and the changing mobility ecosystem have amplified commercial vehicles' (CV) challenges navigating the city streets or finding adequate space to park.
Much of the current research and transportation planning efforts at the urban scale have focused on passenger mobility, giving little attention to CV flows and their parking behavior. Furthermore, collecting CV data at the urban scale is challenging...

Friday Transportation Seminars at Portland State University have been a tradition since 2000. You can join us online at 11:30 AM.
PRESENTATION ARCHIVE
THE TOPIC
The diversity of road users is not equitably accounted for in vehicular and infrastructure design and funding allocation policies, among other areas that impact mobility. This impedes the ability for all road users to experience the same level of safety while traveling. Moving towards equitable road safety for all road users is...
Read moreWebinar: Radar Point Cloud Segmentation using GMM in Traffic Monitoring
Tuesday, November 9, 2021, 10:00am to 11:00am PST
PRESENTATION ARCHIVE
OVERVIEW
Intelligent transportation systems (ITS) change our communities by improving the safety and convenience of people’s daily mobility. The system relies on multimodal traffic monitoring, that needs to provide reliable, efficient and detailed traffic information for traffic safety and planning. How to reliably and intelligently monitor intersection traffic with multimodal information is one of the most critical topics in intelligent transportation research.
In multimodal traffic monitoring, we gather traffic statistics for distinct transportation modes, such as pedestrians, cars and bicycles, in order to analyze and improve people’s daily mobility in terms of safety and convenience.
In this study, we use a high-resolution millimeter-wave (mmWave) radar sensor to obtain a relatively richer radar point cloud representation for a traffic monitoring scenario. Based on a new...

THE TOPIC
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.

THE TOPIC
Existing studies surveying transportation planners in Tribal communities have recognized two challenges: (1) that existing planning analysis tools do not always align with Tribal community context and needs, and (2) that it is not always clear what benefits planning provides to transportation project selection and delivery in Tribal communities. These challenges are outlined in a...
