Project Summary:
There are generally three components to calculating accessibility indices: knowing travel times, knowing the types of activities to which people travel (e.g., land uses), and knowing how much "closer" land uses should be valued over "further away" land uses (e.g., decay functions). All are important; some are more "advanced" for various modes. This research develops a set of geographic information system (GIS) layers (across the entire Minneapolis-St. Paul metropolitan region) that can reliably represent the types of land use activity to which people travel at the neighborhood and regional levels of analysis. This work integrates various GIS datasets with other secondary data sources to generate the desired GIS layers. Detailed data will be generated to adequately capture the small-scale types of land use that would likely be more influenced by transit, cycling, or especially walking. The core of this project is to obtain (from secondary sources), manage, clean, tailor, and in some cases collect parcel-level land use data for the seven-county metropolitan area. Where parcel-level land uses would not be appropriate or applicable (e.g., for mixed-use parcels), it may be necessary to rely on a higher level of aggregation. The findings of this analysis will be integrated as part of the Access to Destinations study to generate accessibility measures for various destinations in the region using various travel modes.
