Friday Transportation Seminar: Turning Streets Into Housing

Friday, October 1, 2021, 11:30am to 12:30pm PDT

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

Wide residential streets in US cities are both a contributor to homelessness and a potential strategy to provide more affordable housing. In residential neighborhoods, subdivision ordinances typically set binding standards for street width, far in excess of what is economically optimal or what private developers and residents would likely prefer. These street width standards are one contributor to high housing costs and supply restrictions, which exacerbate the housing affordability crisis in high-cost cities.

Cities can certainly reduce street widths in new development. But what about existing neighborhoods? Dr. Adam Millard-Ball proposes two strategies through which excess street space can accommodate housing in a formalized way. First, cities could cede part of the street right-of-way to adjacent property owners, either as part of new development or as a means to create space for front-yard accessory dwelling units. Second,...

Friday Transportation Seminar: An Assessment of Bicycle Detection Confirmation and Countdown Devices

Friday, October 8, 2021, 11:30am to 12:30pm PDT

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

For a person on a bicycle at intersections, trail crossings, or midblock locations that are signalized, knowing that they have been detected and how long they must wait to receive a green indication is valuable information. This presentation will summarize the findings from the online survey (1,048 responses), observed behaviors (2,428 persons on bicycle), and an intercept survey ( 234 persons) to understand blue light feedback devices and countdown timers at signalized intersections. 

Findings suggest that the design where the blue light was embedded in the sign was more visible to cyclists and observed by higher proportions of cyclists in the field. Results show that a bicycle signal countdown timer elicited high comprehension rates. At all locations, cyclists indicated that the devices improved their waiting experience.

KEY LEARNING OUTCOMES

  • Results of comprehension surveys on detection feedback devices
  • ...

Webinar: The Impact of Transportation-Related Barriers on Self-Perceived Physical Health among Adults in the US

Tuesday, October 12, 2021, 10:00am to 11:00am PDT

OVERVIEW

Drawing from the framework of social determinants of health, the objective of this study is to investigate the cross-sectional association between transportation-related factors and self-perceived physical health among adults in the U.S.

Data for this study were derived from the 2017 National Household Travel Survey. An analytic sample of 71,235 respondents aged 18 and 64 years was analyzed using binary logistic regression. Of the 71,235 respondents examined, 8.9% perceived their physical health to be poor. About 36% of the respondents had fewer vehicles per individuals in the household.

Controlling for the effects of other factors, respondents who had fewer vehicles per individuals in the household were 1.27 times more likely to report poor self-perceived physical health when compared to their counterparts with more vehicles per individuals in the household (AOR=1.27, 95% CI=1.17-1.39). Having higher education, higher income, and homeownership were inversely associated with poor self-perceived physical health.

The findings of this study suggest that as the gap between the number of household members and the number of vehicles present increases, respondents' self-perceived physical health deteriorates due to the uncertainty in having access to transportation when the need arises. Social workers, engineers, and policymakers should begin working on viable solutions to reduce or eliminate...

Friday Transportation Seminar: Retention of a Diverse Construction Workforce

Friday, October 15, 2021, 11:30am to 12:30pm PDT

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

Having a strong pipeline of workers will be critical for ongoing efforts to improve transportation infrastructure, such as roads, highways, and bridges. This talk first provides an overview of the recruitment and retention of a diverse construction workforce in Oregon. Next are findings from research studies over the last ten years demonstrating the challenges experienced by workers on construction job sites that lead to low retention levels. The talk concludes with a discussion of several initiatives within the construction trades that have been implemented to address job site culture.

KEY LEARNING OUTCOMES

  • Addressing recruitment and retention of a diverse workforce will be needed to ensure a robust pipeline of workers in the transportation workforce
  • Job site culture has a negative impact on retention as well as productivity and safety
  • Efforts by public agencies and contractors can improve job site...

Friday Transportation Seminar: Transportation Planning in Tribal Communities: From Plan Development to Implementation

Friday, October 22, 2021, 11:30am to 12:30pm PDT

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

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 2020 FHWA Research Needs Statement titled Making Transportation Planning Applicable in Tribal Communities.

This study, therefore, seeks to align available planning analysis tools to Tribal community needs based on a range of contextual factors, and to quantify the benefits of planning analysis in the project selection and delivery processes. Additionally, this study seeks to ensure that any findings optimize Tribal Transportation Program funding decision-making in Tribal communities. The audience for the study is primarily Tribal planning staff and,...

Friday Transportation Seminar: Pedestrian Safety and Social Equity in Oregon

Friday, October 29, 2021, 11:30am to 12:30pm PDT

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

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 and People of Color (BIPOC) experience a higher rate of pedestrian injury compared to the statewide average. 

This research also documents pedestrian injuries at the Census tract level and measures factors that influence pedestrian...

Friday Transportation Seminar: Vehicular Design and Resource Allocation Policies for Equitable Road Safety

Friday, November 12, 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. Stay tuned for an announcement of the fall term lineup.

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 critical to improve the quality of life and save lives of those that are most underserved in the transportation sector.

Professor Alyssa Ryan discusses two strategies to increase safety for vulnerable road users. First, a study on road injury differences between drivers of different biological sex is presented. This research highlights the crash conditions and vehicle components that lead to different injury outcomes for female and male drivers, emphasizing the importance of including both representative female and male anthropometry in vehicle testing and design. Next, a research study that explores the...
