GPS/GIS Inspection and Analysis Tools for Highway
Construction
  • Integrated GPS/GIS Application for Inspection and
    Analysis
  • FDOTs Microstation drawings converted into
    Geographical Information System (GIS) Basemaps,
    with correction to the proper projections
    Specifications and Pay Items' Original
    Quantities.
  • Global Positioning System (GPS) Receivers Capture
    Pay Item Locations and Pertinent Dimensions for
    Quantities.
  • Database to Store Inspection Results Observed
    Quality of Construction, Lab. Test Results, etc.
    and Digital Images
  • GIS Analyses and Database Queries Provide Monthly
    Display of Construction Progress and Estimate of
    Quantities, including As-Built Final Drawings and
    Quantities.

Hawaii Department of TransportationVirtual
Reference Station
  • What is VRS (Virtual Reference Station )
  • Real time centimeter measurements within the
    island-wide or state-wide network without setting
    up a base station

10
Estimated miles of leveling
  • Oahu
  • Estimate of 211 miles
  • Maui
  • Estimate of 251 miles
  • Kauai
  • Estimate of 128 miles
  • Big Island
  • Estimate of 410 miles

11
Maryland Department of Transportation Asset Data
Warehouse
Initial Assets to be include in the Data Warehouse
  • Highway Characteristics
  • Pavement
  • Bridge/Structures
  • Drainage
  • ITS
  • Sidewalk

12
Pavement Condition
  • The ARAN uses a combination of high resolution
    video, ultrasonic sensors, accelerometers,
    gyroscopes and GPS to collect data at highway
    speeds
  • The Aran records cracking, rutting, roughness,
    grade, curve radius and more
  • It also records right-of-way video as a permanent
    record of roadway inventory

13
California Department of Transportation
  • U.S. DOT Partners with Caltrans for SafeTrip-21
  • SafeTrip-21, is designed to improve safety and
    reduce congestion by identifying and harnessing
    existing technology and adapting it for
    transportation needs

14
U.S. DOT Partners with California Department of
Transportation for SafeTrip-21
  • Partnership will field test GPS-equipped cellular
    phones from up to 10,000 volunteer commuters and
    transit vehicles transmitting data from roads in
    a 200 mile radius to traffic management centers.
  •  Commuters will have access to real-time traffic,
    transit and road safety information

15
A Responder Problem
Question Theres a rock in the road. How big
is it? Problem How do you convey this
information to someone who isnt there, looking
at the rock alongside you?
