  • An application of regression tree methodology in freeway travel time estimation using speed as a proxy

    Creator:
    Wang, Lijuan
    Abstract:
    Accurate freeway travel time estimation is of increasing importance for the travelers’ information and route guidance system. A non-parametric statistical methodology known as regression trees is deployed in this research for dynamically and accurately estimating freeway travel times for the I5-I205 loop in the Portland Metro area of Oregon using...

  • Differentiating transportation modes using Bluetooth sensor data

    Creator:
    Bathaee, Nadia
    Abstract:
    State departments of transportation, transportation consultants, and other transportation agencies are always in need of data that can be used to better understand how different modes of transportation use the road and highway systems. A variety of automatic data collection technologies have been used to gather these data including video...

  • Design and implementation of a heuristic-based decision support system for nurse scheduling

    Creator:
    Sitompul, Darwin
    Abstract:
    A decision support system (DSS) for nurse scheduling in hospitals is developed and implemented on microcomputer. The system includes algorithms and databases for developing weekly work and shift patterns and combining these into working schedules for nurses for a specified time horizon, and interface modules for the user to interact...

  • Photogrammetric uses of a new-generation analytical stereoplotter in forestry

    Creator:
    Kiser, James D. (James Donald)
    Abstract:
    The development of personal computer software coupled to an analytical stereoplotter allows major gains in efficiency and accuracy in a number of forestry related subjects. This thesis describes the operation of a system developed by Carto Instruments. This thesis demonstrates how area estimates might be made in a systematic way...
