A growing number of transportation agencies are experimenting with mobile LiDAR as a method for collecting very accurate roadway asset data. The Minnesota Department of Transportation (MnDOT) Metro District issued a contract designed at using a combination of LiDAR and imagery data to create a GIS based inventory of barriers and plate beam guardrail. The goals of the project were to:

  • Obtain filtered and classified mobile LiDAR data on several road segments within the Metro.
  • Obtain a metro-wide data set of imagery compatible with Trimble Trident 3-D Analyst.
  • Utilize part of the processed LiDAR data for a 2016 design project.
  • Extract barrier attribute and condition data from images creating a GIS based inventory.
  • Create a barrier asset management plan.
  • Determine future LiDAR and imagery uses at MnDOT.

The project came in under budget and provided far more data than traditional processes. This webinar features Metro District's Trisha Stefanski, P.E. and Brad Canaday, LS. Trisha Stefanski leads the Infrastructure Asset Management unit and is a member of MnDOT's Transportation Asset Management (TAM) Plan Steering Committee and TAM Software Acquisition Selection Committee. She also Chairs the District's GIS Committee. Brad Canaday leads the Metro District's Surveys group. Brad leads the effort to incorporate the use of static and mobile laser scanning at MnDOT for asset extraction.

Richard B. (Dick) Albin, P.E., with the FHWA's Resource Center Safety and Design Technical Services Team, will be the moderator.
