Smart Work Zone System

In the previous Safe-D project 04-104, a prototype wearable Personal Protective Equipment vest was developed and demonstrated that accurately localizes, monitors, and predicts potential collisions between work zone workers and passing motorists. The system also notifies the worker of when they’re about to depart safe geo-fenced safe areas within work zones. While the design supported a successful functional demonstration, additional design iteration is required to simplify, ruggedize, and reduce per unit costs to increase the likelihood of broader adoption. In addition, two new useful components were identified that would support a more effective deployment package. A base-station will be added that provides an edge computing environment for alert algorithm processing, consolidates communications of individual worker positions via a 4G link to a cloud computing environment, and can be coupled with a local RSU to support the broadcast of work zone information to connected vehicles. In a addition, a smart cone device will be added that can help automatically define safe area boundaries and improve communications reliability between workers and the base station. The entire package is being developed to support a broader scale deployment of the technology with the Virginia Department of Transportation.
