Past efforts include data analysis and reporting performance and outcomes for signs, pavement, shoulders, roadsides, drainage, traffic, and bridges. In the 2005 Compass report, measures for bridge inspection and maintenance were added, and historic data was transformed from District to Region-levels. In 2006, Compass reports began presenting trends for pavement condition associated with the agency’s biennial inspection cycle. In addition, the 2006 Compass report took on a slightly more customer-focus by presenting overall results as a report card and by organizing the measures according to their maintenance objectives such as safety, stewardship, and aesthetics.

The primary project deliverables for the Compass 2008 work order include data reduction and preparation of two reports: 1) Compass Wisconsin State Highway 2008 Maintenance, Traffic, and Operations ConditionsExecutive Overview Report and 2) Compass Wisconsin State Highway 2008 Maintenance, Traffic, and Operations Conditions Operational Report on:

  • Shoulders, roadsides, drainage, traffic features (field review data)
  • Signs (SIMS database)
  • Pavement (pavement van data)
  • Bridges (BOS highway structures inventory (HSIS) data)
  • Winter


The work plan is patterned after previous years’ efforts with the following particular emphases for advancing the Compass Program.

  • The 2007 Compass reports will be used as a starting template for the 2008 reports. Again, the work plan includes periodic meetings with the WisDOT Compass Program Manager specifically geared to assess and redesign the various component reports. The 2008 analysis and reporting is expected to build and improve upon the 2007 efforts.
  • For 2008, the analysis of bridges will continue to be done later in the schedule (after pavements). This is compatible with the business processes in the bridge section. The state’s bridge report is due to FHWA by April 1. By waiting until that date to retrieve bridge data for Compass analysis, we can be confident of using the most up-to-date bridge inspection data.
  • The 2008 work plan will continue developing the new approach for reporting pavement data on 2-year cycles.

Overarching research objectives including the following:

  • Work with the Compass Program Manager and other Compass team members to create useful and meaningful measures for understanding and changing maintenance conditions.
  • Work with the Compass Program Manager and BHO managers to assess, revise, and develop the analysis and reporting procedures used for Compass.
