Title:
GIS-Based Analysis of Intelligent Winter Maintenance Vehicle Data
Abstract:
The Wisconsin DOT, in cooperation with eight Wisconsin counties, has embarked on an effort to implement advanced technologies in winter maintenance vehicles. The University of Wisconsin ? Madison is assisting with data management aspects of the effort. The winter maintenance vehicles are equipped with differential GPS receivers and numerous additional sensors that collect environmental data (e.g., pavement and air temperature), equipment status data (e.g., plow up/plow down), and material usage data (e.g., salt application rate). These data are telemetered to a dispatch center and recorded on magnetic media for later downloading. A geographic information system application, dubbed "Wiscplow," has been developed and initially deployed for testing within participating counties. Wiscplow combines vehicle data with manually entered data (e.g., storm durations, vehicle configurations, and labor and equipment cost rates) and with spatial data representing roadway centerlines attributed with functional class, number of lanes, patrol sections, and route systems. Outputs include reports on computed performance measures (e.g., cycle time and hourly average salt application rate by patrol section and storm) and decision management tools (i.e., charts, graphs, and maps) showing relationships among performance measures (e.g., salt application rate versus pavement temperature by patrol section and storm). Both technical and institutional issues are being addressed.
