A contractor in Minnesota initiated a test of the wearable vest for worker presence. An initial test is being conducted with four wearable vest sensors being used in an active work zone, which are supporting the testing of different types of applications in a virtual environment. Data from the sensors are being provided via a Work Zone Data Exchange (WZDx) feed to Waze but not to MnDOT.

Work Zone Smart Vests to Change the Speed Limit Posted
MDOT tested two VerMac Smart Vests in a work zone as well as 12 additional modified sensors containing the same technology. The presence of one worker (or multiple workers) wearing a Smart Vest prototype sensor was used to automatically change the speed limit posted on the digital speed limit sign in the segment that the worker was present.
