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

Maryland Department of Transportation Asset Data
Warehouse
Initial Assets to be include in the Data Warehouse

• Highway Characteristics
• Pavement
• Bridge/Structures
• Drainage

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

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
