Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

    Accessibility and Centrality Based Estimation of Pedestrian Activity and Safety in Urban Areas
    (2015-10) Murphy, Brendan
    The following thesis investigates the feasibility of using metrics of accessibility to jobs, betweenness centrality, and automobile traffic levels to estimate pedestrian behav- ior levels and automobile-pedestrian collision risks within an urban area. Multimodal count and crash report data from Minneapolis, Minnesota are used as a test of this scal- able, translatable modeling framework; multiple stepwise linear regression is performed to compile a set of explanatory variables from which to construct a predictive model of pedestrian movement. The existence of the Safety In Numbers (SIN) phenomenon is in- vestigated within both the raw and estimated pedestrian movement data; the SIN effect is the phenomenon where pedestrians are found to be safer from collisions, on average, when there are more pedestrians present in a given intersection, street, or area - that is, that the per-pedestrian risk of injury inflicted by drivers of automobiles decreases as a function of the increasing volume of pedestrian traffic. Economic accessibility, between- ness centrality, and Average Annual Daily Traffic (AADT) were found to be significant predictors of pedestrian traffic at intersections in Minneapolis, and the SIN effect was observed in both the raw and estimated pedestrian movement data when combined with the aggregated crash data. This investigation shows the potential utility of such a model that is both scalable to larger geographic areas, and translatable to varying jurisdictions due to its reliance on nationally-available datasets. Policy implications and concerns surrounding use of the Safety In Numbers effect in planning and engineering, and issues of data quality and availability in urban geographic science, are discussed.

    Creating and Sustaining Equity in Little Canada through Pedestrian, Bicycle, and Public Transit Connectivity
    (Resilient Communities Project (RCP), University of Minnesota, 2022) Berger, Jacob; Burstein, Regina; Koenen, Frank; Paquin, Jarred
    This project was completed in partnership between the City of Little Canada and the University of Minnesota’s Resilient Communities Project (https://rcp.umn.edu/). The goal of this project was to research how the City of Little Canada might equitably prioritize improvements to its transportation infrastructure to provide safe, accessible, and connected pathways for people walking, rolling, biking, and taking public transit. City of Little Canada project lead Corrin Wendell collaborated with a team of students in Dr. Greg Lindsey’s course PA 8081 to conduct four analyses - demographic, crash risk, connectivity, and economic – and solict feedback from the community through an online survey and several key informant interviews. A final student report, executive summary, and PowerPoint presentation slides from the project are available.

    The Impact of Weather Conditions and Infrastructure Design on the Mobility of People with Impaired Vision
    (2019-07) Achtemeier, Jacob
    Nineteen normally-sighted, low vision, and blind pedestrians provided self-reported effects of environmental, infrastructural, and social factors influencing outdoor mobility in the Minnesota’s Twin-Cities metropolitan area. Focus groups and interviews were conducted to gather data on challenges associated with year-round, independent outdoor navigation emphasizing winter pedestrian mobility. Study themes included weather pressures (e.g., precipitation, temperature), infrastructural/engineering features (e.g., street, sidewalk, intersection design and maintenance), and safety concerns related to motorists and obstacles. Results identify pedestrian hazard impacts on quality of life and behavioral adaptations visually-impaired pedestrians create to increase safety and efficiency during mobility. Conclusions prompt considerations for urban planners, engineers, community activists, and stakeholders concerning mobility issues for visually-impaired pedestrians. Recommendations are provided to promote equity and wellbeing in pedestrian mobility.

    Visualize SLP: Online Visual Preference Survey of Complete Streets Features in St. Louis Park, MN
    (2017-05) Hayford Oleary, Sean; Hanson, Luke; Wardoku, Maria
    Results of a visual preference survey conducted in the City of St. Louis Park, Minnesota in 2017, both online and in-person. Residents surveyed showed preference for streets with sidewalks, lighting, and plantings, both in composite images and real-life scenes of streets.
