Estimated Time of Arrival (ETA) is a projection of when a vehicle, shipment, or person is expected to arrive at a specific destination. ETA is used in transportation, logistics, and travel industries to provide customers with an expected timeframe for deliveries, flights, or arrivals. It helps in planning and managing schedules, improving efficiency, and enhancing customer communication. Accurate ETAs can significantly impact logistics operations and customer satisfaction by minimizing uncertainty and facilitating timely decision-making.
