About the research


Automated machine guidance (AMG) links sophisticated design software with construction equipment to direct the operation of the machinery with a high level of precision, improving the speed and accuracy of the transportation construction process. Because AMG eliminates much of the guesswork, manual control, and labor involved in traditional methods, it improves worker safety and saves agencies and contractors time and money, enhancing their ability to deliver transportation construction projects better, faster, and cheaper. This technology has the potential to improve the overall quality and efficiency of transportation project construction. The objective of this research is to develop guidelines for use of AMG technology for state transportation agency construction projects. The guidelines should (1) include technical procurement specifications for AMG technology; (2) provide guidance on the use of such technology in construction projects; and (3) address the implementation of AMG technology into construction techniques (including the provision of electronic files and models to support the AMG process).
