You are Where?

Every year more than 100 workers lose their lives in road construction work zones. U.S. DOT’s top priority is to eliminate fatalities in construction work zones. At the University of Minnesota, Duluth, a safety warning system was designed under a project funded by the Minnesota Department of Transportation. The system uses global positioning satellite (GPS) receivers to determine the relative physical position of workers around a heavy construction vehicle to proactively provide constant visual situational awareness about the proximity of the workers to the construction vehicle’s operator. This article provides a summary of this project.
