Abstract: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: 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 RFID and magnetic systems. 3. A directional alert display function was positively validated at a real-world construction site. 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.
