    (Center for Transportation Studies, University of Minnesota, 2018-11) Fan, Yingling; Wiringa, Peter; Guthrie, Andrew; Ru, Jingyu; He, Tian; Kne, Len; Crabtree, Shannon
    The Transit Service Frequency App hosts stop- and alignment-level service frequency data from 559 transit providers around the globe who have published route and schedule data in the General Transit Feed Specification (GTFS) format through the TransitFeeds website, a global GTFS clearinghouse. Stop- and alignment-level service frequency is defined as the total number of transit routes and transit trips passing through a specific alignment segment or a specific stop location. Alignments are generalized and stops nearby stops aggregated. The app makes data easily accessible through visualization and download tools. It allows the user to identify stop and alignment frequency at thousands of locations around the globe, as well as export data for cross analysis using GIS technology.

    Visualizing Transportation Happiness in the Minneapolis-St. Paul Region
    (Center for Transportation Studies, University of Minnesota, 2020-03) Fan, Yingling; Ormsby, Travis; Wiringa, Peter; Liao, Chen-Fu; Wolfson, Julian
    This report describes the data and methods used to generate the interactive Minneapolis-St. Paul Transportation Happiness Map at https://maps.umn.edu/transportation-happiness. The map illustrates spatiotemporal differences in travelers' happiness ratings on the streets and roads in the Minneapolis-St. Paul metropolitan region. Map users can interactively explore street and road segments that are associated with positive and/or negative emotional experiences based upon their interested travel modes and travel time periods. For policy makers who are interested in improving people's transportation happiness, the map provides important insights on road and street segments that are in need of closer investigations for future improvements.
