Transportation

TransportationApplied to transportation projects, 3D laser scanning provides a non-intrusive, rapid method for collecting precise, comprehensive, detailed information from existing conditions. Some advantages include:

  • Minimum Personnel Exposure to Traffic
  • Minimum Traffic Disruption or Diversion
  • Captures Extensive Existing Conditions
  • Reduces or Eliminates Site Re-visits
  • Quantity of Data Supports Robust Spatial Analysis

Great Lakes Geomatics is officially prequalified to work with the Michigan Department of Transportation (MDOT) in the following areas:

  1. Right of Way Surveys
  2. Photogrammetric Control Surveys
  3. Hydraulic Surveys
  4. Structure Surveys
  5. Road Design Surveys 

 

Americans with Disabilities Act Ramps – Detroit

ada-rampsAs a subcontractor to the City of Detroit, we surveyed over 450 city street intersections during a year-long pilot project to confirm compliance of ADA Ramps in Downtown Detroit and along the Woodward Corridor from Downtowns to the Wayne State University Area.

The layouts we developed were used to rebuilt out-of-compliance ramps Laser scanning technology proved invaluable in rapidly and accurately collecting the enormous amount of spatial data required by this half-million-dollar project.

Square Lake Road – Oakland County

square-lake-roadOur experienced team conducted a Road Design Survey for MDOT covering approximately 1.5 miles of Square Lake Road from Woodward Avenue to Telegraph Road. Horizontal and vertical control was established using GPS and conventional surveying methods.


square-lake-road2All surface features were located and mapped using a combination of laser scanning, GPS, and conventional surveying. The usual errors associated with the registration of multiple laser scans were significantly reduced by including accurate survey control at each scan position, a method consistently employed by Great Lakes Geomatics to ensure high quality results. Use of laser scanning technology allowed all surveying activities to take place outside the influence of traffic.



I-75 / I-696 Interchange – Royal Oak / Hazel Park

I75-696-interchangeWith the average traffic flow of 360,000 vehicles per day, the I-75/ I-696 Interchange is the busiest intersection in the State of Michigan. This aspect would normally give rise to various safety concerns when surveying. We, however were able to scan and provide surveys of six of the bridges that make up the intersection without any disturbance to normal traffic flow.

By using laser scanning technology we were  able to accurately collect data from over 40 separate scan positions encompassing the entire interchange without ever entering into a roadway. Mapping point data was collected by our Survey Technicians using the ‘Virtual Surveyor’ module of Leica Geosystems’ Cyclone software.
