Active Work Zone Safety Using Emerging Technologies (Modification No. 2)

The major objectives of this research were to (1) identify technologies that can be used in real time to detect a hazardous proximity situation between construction equipment and pedestrian workers and provide an appropriate warning; (2) develop a Bluetooth-based proximity alert system; and (3) evaluate the reliability and effectiveness of the technologies through extensive field tests. Some of the pertinent conclusions from this study are: 1. Experimental results in controlled environments demonstrate that tested systems provided reliable results with an appropriate alarm with slight performance differences; 2. The Bluetooth proximity system was tested as more effective in terms of cost, small form factor, easy installation, and flexible programming against Radio Frequency Identification (RFID) and magnetic systems; 3. A directional alert display function was positively validated at a real-world construction site; and 4. From real-world field tests, the Bluetooth proximity system provided reliable performance results and was positively evaluated by participating equipment operators and pedestrian workers.
