Abstract: The real-time location tracking of workers on a transportation vehicle using a wearable sensor and wireless stations. Embarkment of workers on the transportation vehicle may include capturing an image of an identification document and performing optical character recognition on the document. The embarkment of workers may also include scanning a worker's wearable sensor using a sensor reader and capturing an image of the face of the worker using a camera on the transportation vehicle. The communication between the wearable sensor and wireless stations may be monitored, and the absence of communication over at time period used to indicate a missing worker.
