GPS/GIS Inspection and Analysis Tools for Highway Construction Integrated GPS/GIS Application for Inspection and Analysis • FDOT’s 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.

Maryland Department of Transportation Asset Data Warehouse • Initial Assets to be include in the Data Warehouse • Highway Characteristics • Pavement • Bridge/Structures • Drainage • ITS • Sidewalk
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
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
Question: “There’s a rock in the road. How big is it?” Problem: How do you convey this information to someone who isn’t there, looking at the rock alongside you? A “Responder” Problem
What is Responder System? GPS Cellular modem Camera Tablet PC Satellite modem
