Abstract:

In order to reduce risky behavior around workzones, this project examines the effectiveness of using in-vehicle ; messages to heighten drivers’ awareness of safety-critical and pertinent workzone information. ; This investigation centers around an inexpensive technology based on Bluetooth low-energy (BLE) tags ; that can be deployed in or ahead of the workzone. A smartphone app was developed to trigger non-distracting, ; auditory-visual messages in a smartphone mounted in a vehicle within range of the BLE ; workzone tags. Messages associated with BLE tags around the workzone can be updated remotely in ; real time and as such may provide significantly improved situational awareness about dynamic ; conditions at workzones such as: awareness of workers on site, changing traffic conditions, or hazards in ; the environment. Experiment results indicate that while travelling at 70 mph (113 km/h), the smartphone ; app is able to successfully detect a long-range BLE tag placed over 410 feet (125 meters) away on a ; traffic barrel on a roadway shoulder. Additional experiments are being conducted to validate the system ; performance under different roadway geometry, traffic, and weather conditions.
