Estimated Time of Arrival (ETA) refers to the predicted time when a vehicle, person, or shipment is expected to reach a specific destination. This calculation considers various factors, such as distance, speed, and potential delays, providing a useful guideline for planning and coordination. ETAs are commonly used in transportation, logistics, and travel. For example, ride-sharing apps like Uber and Lyft display ETAs to inform passengers when their driver will arrive. Similarly, delivery services use ETAs to keep customers updated on when their packages will arrive, enhancing overall service efficiency and customer satisfaction.
