Personal Warning Sensor for Road Construction Workers

This study demonstrated the capabilities of a work zone intrusion alarm system, called Advance Warning and Risk Evasion (AWARE), during a Minnesota paving project. The portable radar-based technology intelligently detects and tracks potential vehicle intrusion threats, as well as worker locations, to warn both workers and errant drivers. The research project’s Technical Advisory Panel observed the system in operation by a road crew in the Minneapolis area and gleaned insights about the technology and data it collects. Study authors also initially hoped to analyze raw individual vehicle trajectory data to assess intrusion behaviors in detail; however, the required data was unavailable due to system limitations.
