The Ann Niles Active Transportation Lecture series continued in 2016 with guest speaker Vanessa Garrison of GirlTrek

Each year, the Ann Niles Active Transportation Lecture Endowment brings a guest speaker to Portland, Oregon. We seek people from all over the world who have made great strides in advocating for health, safety, and bicycle and pedestrian access, and bring them together with the Portland transportation community to share methods and inspiration. The annual forum furthers IBPI's mission to facilitate the exchange of knowledge among scholars, practitioners and community advocates focused on walking and biking.

Vanessa is a passionate advocate of social justice issues and has focused her work on improving health outcomes and quality of life for black women and girls....

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...
