Ground Traffic Control: PennDOT Dives into Laser-Guided Equipment at Airport Job

This article describes an innovative proposal by the Pennsylvania DOT to include specifications for automated precision grading by use of GPS technology. A major PennDOT project is using the new specifications, and the new technology is being evaluated. It is known as stakeless grading because machines work from GPS coordinates. This project is a special test because of the complex curves involved in what is a major access road linking the airport to I-80. System components are described, including the wireless, integrated GPS system and receiver and radio. It uses dual-constellation satellite tracking, which gives 40 percent more coverage than conventional GPS. Additional enhancements are also described. Among the advantages PennDOT expects are: smother ride, faster completion and lower costs, as more contractors use the technology.
