While the number of public bike share systems in the United States grew considerably in recent years, early evidence indicated that many systems were not serving the diverse populations of cities, particularly lower-income residents and people of color. Lack of bike share stations in...

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...

Friday Transportation Seminars at Portland State University have been a tradition since 2000. You can join us online at 11:30 AM.
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...

Friday Transportation Seminars at Portland State University have been a tradition since 2000. You can join us in person at 11:30 AM, or you can also watch online.
This seminar will include two papers that will be presented earlier in the week at the Annual Meeting of the Transportation Research Board in Washington, DC.

Equity requirements in shared micromobility programs have become increasingly prevalent in recent years, but our understanding of the scope and breadth of these requirements has been relatively limited. To address this gap in understanding, we collected documentation about 239 shared micromobility programs from the U.S. and have compiled all the data into an online, interactive dashboard. In this webinar, we will discuss the kinds of equity requirements that are most prevalent, the strategies cities/agencies employ to operationalize equity, and the extent to which these programs are monitored and evaluated. We’ll present findings from our review of 239 U.S. programs, supplemented by five case studies.
In addition, we’ll introduce attendees to two practitioner-focused tools we created to accompany this work:
1)...

As metropolitan area governments and others promote density-promoting “smart growth” policies, finer analysis is needed to quantify the impact of such policies on households' transportation and housing costs. Existing research suggests that households in urban areas trade-off between housing costs and transportation costs, but does not explore how policies to increase urban densities might explicitly impact this balance. Furthermore, the research does not adequately distinguish between the effect of urban area density and the effects of other factors associated with urban area density (e.g metropolitan area size and household incomes) on housing costs. This research uses the 2000 Census Public Use Micro Sample (PUMS) person and household data from 23 of the nation's most densely populated states to identify the impact of increased population density on three housing cost measures: household rents, housing unit values, and monthly mortgage payments. Log linear models were estimated for each housing cost measure using least-squares regression. Dependent variables included household, housing unit, and geographic area characteristics, including population density. The models were found to be very similar to one another in terms of the statistical significance...

Connecting with cities and bike share operators from across the United States, Portland State University conducted a nationwide scan on what programs and initiatives were running to address equity in bike share. The report “National Scan of Bike Share Equity Programs” documents responses from over 70 bike share systems. This resource will help cities and operators navigate the range of actions that have been implemented to make bike share systems more equitable, examine successful strategies employed across the U.S., and understand how those successes (and challenges) are being measured and articulated. In doing so, we hope the report helps bike share systems learn from the experiences of others, innovate, and more quickly move toward greater equity. The research team will be joined by a bike share operator to discuss what they learned, best practices, and where they see the future of bike share equity programs headed.
This webinar is based on a study funded by the Better Bike Share Partnership and the National Institute for Transportation and Communities (NITC) and conducted at...
