ETA, or Estimated Time of Arrival, refers to the predicted time when a vehicle, person, or shipment is expected to reach a specific destination. This estimate is often used in transportation, logistics, and travel planning to help individuals and organizations manage their schedules effectively. Factors influencing ETA can include distance, traffic conditions, weather, and the mode of transportation. For example, a flight's ETA may change due to delays caused by air traffic control or severe weather, while a delivery truck's ETA might be affected by road construction or heavy traffic.
