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 discussion of considerations for wayfinding technology, human subject research design, findings and lessons learned across the two projects.

KEY LEARNING OUTCOMES

  • Foster greater awareness related to the navigation preferences of visually impaired travelers
  • Enable a better understanding of supports for seamless navigation
  • Create familiarity with the Santa Barbara Sense of Direction Scale
  • Share conceptualization of sustainable impacts in cities pertaining to pedestrian mobility

Abstract: Findings will be presented on an evaluation of two innovative bicycle facilities installed in late summer and early fall 2009 in downtown Portland aimed at providing a more separated and comfortable experience for cyclists. The SW Broadway cycle track (near PSU) and the couplet of buffered bike lanes on SW Stark and SW Oak were evaluated to understand how they are functioning on multiple levels. Each facility involved removing a motor vehicle lane by restriping to provide additional roadway space to bicyclists. The facilities were evaluated after they had been in place for approximately one year. Data collected to support this evaluation consisted of surveys of multiple user groups for each facility type, and video data collected by the City of Portland Bureau of Transportation at intersections along each of the routes to understand the facilities' impact on traffic flow, operations and user interactions.

PRESENTATION ARCHIVE

OVERVIEW

Since 2005, Portland State University has periodically surveyed occupants of recently developed  higher-density and mixed-use projects near transit, often referred to as Transit-Oriented Developments (TODs). The general objectives of the surveys were to better understand actual transit use, among other factors, of residents in these buildings. Between 2005 and 2018, the research team surveyed residents of nearly 50 TODs. With funding from Metro and the National Institute for Transportation and Communities, the research team carried out a two-pronged study drawing on this wealth of data. First, we explore geographic differences within the Portland region in terms of travel behavior and attitudes of TOD residents, including differences between TODs within the city of Portland, in eastside suburbs, and in westside suburbs. Second, we conducted a second wave of surveys for select TODs to understand if travel behavior or attitudes changed over time, particularly as neighborhoods surrounding the buildings were built up. In this webinar, we will present select findings from both aspects of the study.

OVERVIEW

Many transit agencies plan to automate their fare collection and limit the use of cash, with the goals of improving boarding and data collection while lowering operating costs. Yet about 10% of adults in the United States lack a bank account or credit card, and many either rely on restrictive cell-phone data plans or don’t have access to internet or a smartphone. 

This webinar will present part of a larger research project exploring these issues in the cities of Denver, Colorado, and Eugene and Portland–Gresham, Oregon. In this part, we explore the tradeoffs between reducing cash acceptance, ridership and the costs of fare collection systems. How much does it save to reduce cash acceptance, verses ridership and equity impacts?

We will also present a cost-effectiveness framework that combines a qualitative and quantitative analysis and use this model to explore case scenarios in our three cities. The model shows that adding a retail network to...

OVERVIEW

Planners and decision makers have increasingly voiced a need for network-wide estimates of bicycling activity. Such volume estimates have for decades informed motorized planning and analysis but have only recently become feasible for non-motorized travel modes.

Recently, new sources of bicycling activity data have emerged such as Strava, Streetlight, and GPS-enabled bike share systems. These emerging data sources have potential advantages as a complement to traditional count data, and have even been proposed as replacements for such data, since they are collected continuously and for larger portions of local bicycle networks. However, the representativeness of these new data sources has been questioned, and their suitability for producing bicycle volume estimates has yet to...
