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.

    Network and Land Use Data for "Indiana Interurban Networks"
    (2016-07-13) Xie, Feng; Levinson, David M; dlevinson@umn.edu; Levinson, David M; University of Minnesota Nexus Research Group
    This dataset contains the network and land use data for our Indiana Interurban study published as Chapter five "Indiana Interurban Networks" in the book titled "Evolving Transportation Networks" (published by Springer in 2011). The first tab contains a list of stations included in our model and their x/y coordinates. The second has a list of links with their start and end nodes (Station IDs), their open/close years, and Operator ID. The third documents a list of Operators and their IDs. The fourth has a list of counties in Indiana, the x/y coordinates of their centroids, and historical population data from 1897 to 1941. Historical data are only available by decade at the county level, and we calculated years in between by interpolation. the last tab has a list of tracts, the x/y of their centroids, and historical population data from 1897 to 1941 (tract population is approximated assuming population in a county is evenly distributed within county boundary).

    SIGNAL : System of Integrated Growth of Networks and Land Use
    (2016-07-13) Xie, Feng; Zhu, Shanjiang; Levinson, David M; dlevinson@umn.edu; Levinson, David M; University of Minnesota Nexus Research Group
    This software models the co-evolution of land use and transportation network as a bottom-up process by which re-location of activities and expansion of roads are driven by interdependent decisions of individual businesses, workers, and road owners according to simple decision rules. A Simulator of Integrated Growth of Networks And Land-use (SIGNAL) is developed to implement these decentralized decision making processes, in which the Gini index and equivalent radius were computed to describe and track down the spatial patterns of space and network.
