    Access Across America: Auto 2018 Data
    (2020-01-31) Murphy, Brendan; Owen, Andrew; aowen@umn.edu; Owen, Andrew; University of Minnesota Center for Transportation Studies, Accessibility Observatory
    These data were created as part of a study that examined the accessibility to jobs by auto in the 50 largest (by population) metropolitan areas in the United States. It is the most detailed evaluation to date of access to jobs by auto, and it allows for a direct comparison of the auto accessibility performance of America's largest metropolitan areas. These data are part of a longitudinal study. The data available describe access to jobs by auto in the states of Arkansas, California, District of Columbia, Florida, Illinois, Iowa, Maryland, Massachusetts, Minnesota, North Carolina, Tennessee, Washington, and Virginia, and the metropolitan areas within these states.

    Access Across America: Bike 2019 Data
    (2021-01-29) Owen, Andrew; Murphy, Brendan; aowen@umn.edu; Owen, Andrew; University of Minnesota Center for Transportation Studies, Accessibility Observatory
    These data were created as part of a study that examined the accessibility to jobs by bicycling in the 50 largest (by population) metropolitan areas in the United States. It is the most detailed evaluation to date of access to jobs by biking, and incorporates a Level of Traffic Stress analysis to allow calculation of access to jobs on bike networks of different traffic stress tolerances. This dataset allows for a direct comparison of the biking accessibility performance of America's largest metropolitan areas. These data are part of a longitudinal study. Access Across America: Bike 2017 data are available at https://conservancy.umn.edu/handle/11299/211418, however the 2017 version of this dataset was produced without implementation of Level of Traffic Stress analysis, and the methodologies differ substantially.

    Block-level accessibility data for managed lanes in the Twin Cities, 2019
    (2020-03-24) Carlson, Kristin, M; Owen, Andrew; carl4498@umn.edu; Carlson, Kristin, M; University of Minnesota Center for Transportation Studies, Accessibility Observatory
    These data are the results of an automobile accessibility analysis for MnPASS managed lane corridors within the Metropolitan Council jurisdiction. The details of the "Tier 1" managed lanes selected for this study can be found in the 2040 Thrive MSP Transportation Policy Plan (TPP). Census block level access to jobs is evaluated for the Existing/Under Construction MnPASS corridors and compared to the planned corridors included in the Tier 1 Current Revenue Scenario. Accessibility change is measured as the number of additional jobs a worker can reach when Tier 1 MnPASS corridor speeds are allowed compared to general purpose lane speeds, for the same departure time of day and travel duration.

    Block-level accessibility data for transit-way evaluation in the Twin Cities metropolitan region, 2019
    (2020-03-06) Carlson, Kristin; Owen, Andrew; carl4498@umn.edu; Carlson, Kristin; University of Minnesota Center for Transportation Studies, Accessibility Observatory
    This data is used in the evaluation of five transitway network scenarios for their impact on transit accessibility in the Metropolitan Council's jurisdiction. The accessibility change is interpreted as the number of additional jobs a worker can reach when the selected bus rapid transit alternative is included in the transit network compared to the baseline accessibility level for the same travel duration. The scenarios analyzed in this report include the following: • May 2019 baseline vs. Funded baseline (C Line, Orange Line, Green Line Extension) • Funded baseline vs. Prospective network (D Line, B Line, E Line) • Funded baseline + B Line, E Line vs. Prospective network • Funded baseline + D Line, E Line vs. Prospective network • Funded baseline + D Line, B Line vs. Prospective network

    Block-level, non-work accessibility data for planned transitways in the Twin Cities
    (2021-01-12) Carlson, Kristin; Owen, Andrew; carl4498@umn.edu; Carlson, Kristin; University of Minnesota Center for Transportation Studies, Accessibility Observatory
    Accessibility to grocery stores, primary healthcare, elementary, middle, and high schools by transit is measured for the Twin Cities. Census block-level minimum travel times to the first, second, third,...,tenth destination are calculated before and after incorporating services changes to the transit network. The transit network baseline includes the Green Line extension and Orange Line. Five planned transitways are evaluated against the baseline including the B Line and local route 21 changes, the D Line and local route 5 changes, the E Line and local route 6 changes, the Gold Line, and the Rush Line. The analysis is completed for four departure windows during the weekday. The report associated with this data aggregates across the Twin Cities metropolitan worker population and disaggregates by worker demographics.
