The ETA full form is Estimated Time of Arrival (‘एस्टीमेटेड टाइम ऑफ अराइवल’ या ‘आगमन का अनुमानित समय' या 'पहुंचने का संभावित समय'). It is used in Navigations applications like Google Map, Ride related services like Ola and Uber Cab, Airline services like Airport, Parcel Tracking platforms like e-kart and DTDC.

The Internal Factors can be Vehicle condition, Driver’s Behaviour, Loading and Dispatch. The External Factors can be Weather, Road Traffic, Customs Inspection, and Crowding at the Facility.
In the Logistics sector, the ETA means the arrival time of a parcel or package at the port or hub. The ETD means the final delivery to the customer or destination address.
