OVERVIEW

In this presentation we will highlight our past research on human indoor-outdoor wayfinding on an urban college campus. Our work is aimed at facilitating independent travel for people with blindness and low vision. Our research was funded by two successive grants from the National Institute for Transportation and Communities/US Department of Transportation. One of the central research questions sought to capture wayfinding preferences, information needs, and lived experiences of blind and low-vision pedestrian travelers. The projects afforded close collaboration with external partners, and foremost the American Printing House for the Blind. Our focus in the presentation will be on the...

OVERVIEW

Recreational trails serve as valuable transportation corridors and support the health of users. Wheelchair accessibility of recreational trails depends on a variety of conditions, including slope, cross-slope, and surface characteristics. This project focused on improving the firmness and stability of a 0.2-mile section of trail that was otherwise accessible. The existing trail surface consisted of loose ¼” off-specification aggregate on native soil. A volcanic ash-Portland cement binder, studied in prior research, was batched, distributed, mixed, wetted, and compacted on site to improve the firmness and stability of the surface resulting in a smoother surface with less rolling resistance. The webinar will present details of the trail conditions, materials, batching, placement, and surface characteristics before and after treatment.

This project will help demonstrate how sustainable ("green") streets contribute to the well-being of a community, including the physical and mental health of older and younger adults, along with the environment and economy. The project will collect data in Portland, OR neighborhoods to answer the following research questions:

Are residents living near sustainable streets more physically active in their neighborhood?

Do residents living near sustainable streets interact with neighbors more and demonstrate higher levels of neighborhood social capital?

What are residents’ opinions of sustainable streets?

Are there variations in responses to sustainable streets by age or other demographics? In particular, how to older adults differ from younger adults?

Does the implementation process and design affect green street outcomes?

Do sustainable streets affect home values?

How do green streets affect stormwater flows, urban heat island, and carbon sequestration in Portland neighborhoods?

The project includes a survey of residents in two neighborhoods with green street features and two control neighborhoods; an environmental assessment of the green street treatments; and an analysis of housing values using a hedonic modeling approach.

The project will be guided by an Advisory council of members of various stakeholder organizations...
