  • Abstract:
    The South Dakota Department of Transportation (SDDOT) uses a sign-oriented, link-node signpost location method in which "uniform" Mileage Reference Markers (MRM) are placed at approximate intervals of one mile and "special non-uniform" MRMs are placed at intersections, structures, county lines, municipal and urban limits and at roadway discontinuities. The location of a particular inventoried highway attribute is its displacement, in increments of one thousandth of a mile, from the nearest MRM marker. Two primary objectives were established for this 10-month research project conducted during 1992. The first was to demonstrate how a combination of Global Positioning System (GPS) technology and current elapsed-distance technology can be applied within SDDOT to cost-effectively generate geographic coordinates for the existing MRM-based highway attribute data. This process will make the complete MRM attribute database usable in the State's developing Geographic Information System (GIS) applications. This objective was accomplished using a test segment on US Highway 12 in the Aberdeen Region for GPS data collection, and existing MRM-tagged highway attribute data for the test area from a variety of SDDOT sources. Both the GPS data and the GPS-tagged MRM attribute data were imported into the Department's Intergraph GME GIS environment to demonstrate the techniques. This process is summarized in the Research Task 5, 6, 7 and 8 sections of this report. The second objective was to analyze SDDOT application opportunities and prepare a GPS technology implementation plan for consideration by SDDOT management. The results of that analysis and an outline of the implementation plan are described in the Research Task 2, 3, 4 and 9 sections of this report. Task 9 includes the research team's policy and procedures recommendations for a successful implementation within SDDOT. This project has been structured to provide SDDOT with direct and "hands-on" experience with GPS and to validate the use of GPS in South Dakota in SDDOT applications. All program objectives were accomplished.
