Earlier this year, RSI researcher Brian Davis helped lead two workshops for practitioners as part of a research project sponsored by the Minnesota Local Road Research Board.

The “Innovative Technology Workshops on LIDAR” provided information to city and county engineers and GIS professionals who were interested in learning more about LIDAR (light detection and ranging) and its potential traffic applications. The workshops were held in Dakota County (West Saint Paul, MN) and Saint Louis County (Duluth, MN) and featured both a classroom component and a live demonstration of 3D LIDAR technology collecting data at a test site.

Kaye Bieniek, Olmsted County Engineer, praised Davis’s work on the LIDAR research project and the workshops. “[Brian] gave terrific explanations when many questions were asked [and was] thorough in the information generated,” she said.

LIDAR is becoming a more frequently used tool among state and county DOTs—for instance, to collect information about the geometry of objects in its field of view such as roadway and roadside features and the relative position and trajectories taken by vehicles. LIDAR scanning can be useful in a number of applications, including real-time driver-assist systems, vehicle and pedestrian counting and trajectory data collection, surveying and construction, and facilities inspection and asset management.
