    The Health and Transportation Nexus: A Conceptual Framework for Collaborative and Equitable Planning
    (Minnesota Department of Transportation, 2022-05) Fan, Yingling; Phua, Peiyu
    Transportation is a crucial contributor to health. It not only directly shapes the social and physical environments but also determines the type of places where people can live, learn, work, and play in their everyday lives. This project develops a conceptual framework for collaborative and equitable health and transportation planning by extending the social determinants of health framework to include three major pathways through which transportation factors operate on health and equity outcomes. The three major pathways are behavioral health, environmental health, and social exclusion, which are identified via a thorough review of the academic literature and gray resources on health and transportation connections. Of the three pathway mechanisms, social exclusion and environmental health are intrinsically linked to social equity and justice issues. We further review state-level initiatives linking transportation to health and interview six state departments of transportation that are pioneers in advocating and implementing integrated health and transportation planning. The interview results are summarized and discussed in the report. Based on the interviews, we make recommendations for the Minnesota Department of Transportation to help further its efforts on integrated health and transportation planning.

    Pedestrian and Bicycle Crash Risk and Equity: Implications for Street Improvement Projects
    (2019-06) Lindsey, Greg; Tao, Tao; Wang, Jueyu; Cao, Jason
    Transportation managers need information about crash risk and equity to prioritize investments in street networks. This case study uses data from Minneapolis, Minnesota, to illustrate how estimates of pedestrian and bicycle crash risk and assessments of inequities in the distribution of that risk can inform prioritization of street improvement projects. Crash numbers and frequencies for pedestrian and bicycle crashes at intersections and mid-blocks in Minneapolis are determined for the 2005-2017 period. New models of pedestrian and bicycle crash risk at both intersections and mid-blocks that control for exposure are introduced and used to predict crashes at all intersections and mid-blocks in the city. Statistical tests are used to assess the equity of distribution of estimated crash risk between areas of concentrated poverty with majority-minority populations and other areas in the city. Crash indexes based on predicted crashes are used to illustrate how increased emphases can be placed on pedestrian and bicycle safety in street improvement rankings. Results show that pedestrian and bicycle crash risk is correlated with exposure, that different factors affect crash risk at intersections and mid-blocks, and that these factors differ for pedestrian and bicycle crashes. Results also show that mean crash risk is higher in neighborhoods with lower incomes and majority-minority populations. For street improvement projects in the city, different rankings result when segments are ranked according to modeled pedestrian and bicycle crash risk in addition to total crash rates based on historical numbers of crashes at particular locations. Results generally affirm efforts by the Minneapolis Department of Public Works to increase emphases on pedestrian and bicycle safety and equity in its prioritization of street improvements.
