| 摘要： | In order to reduce risky behavior around work-zones, this project examines the effectiveness of using in- vehicle messages to heighten drivers' awareness of safety-critical and pertinent work-zone information. This investigation centers around an inexpensive technology based on Bluetooth low-energy (BLE) tags that can be deployed in or ahead of the work-zone. A smartphone app was developed to trigger non- distracting, auditory-visual messages in a smartphone mounted in a vehicle within range of the BLE work-zone tags. Messages associated with BLE tags around the work-zone can be updated remotely in real time and as such may provide significantly improved situational awareness about dynamic conditions at work-zones 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. |
