This study will evaluate the effectiveness of the work zone intrusion detection and alert system prototype that was developed by Dr. Ozan by testing the system at a number of actual work sites in North Carolina. The project will employ a number of data collection and scientific observation methods to test the applicability of the technological approach in the field. The following methods will be used: (1) safe intrusion experiments to measure the effectiveness of the intrusion detection and timely activation and the dissemination of the alerts; (2) the observation of the utilization of the device by the study participants (e.g., workers, field engineers) to evaluate the usefulness of the system to be used in actual work areas; (3) conducting a survey to capture opinions of the study participants in various aspects of the system (userfriendliness, ease of setup, performance, compatibility with the work zone environment).
