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.

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

• 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
Pavement Condition

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

A “Responder” Problem
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?
