What does ETA mean?
ETA stands for estimated time of arrival – the expected time of arrival at the destination. It is calculated from the route, the current vehicle position, traffic conditions and planned stops. In modern TMS and tracking systems the ETA is updated in real time. It is decisive for the consignee in preparing staff, the loading dock and warehouse space.
What does ETD mean?
ETD stands for estimated time of departure – the expected departure time from the consignor or from an intermediate point. It matters when consignments have to be collected within particular time windows or when just-in-time production chains must be maintained. Delays to the ETD feed directly through to the ETA at the consignee.
ETA in modern tracking
Professional freight platforms and TMS systems calculate the ETA dynamically from GPS data, traffic data and historical transit times. When there is a deviation the system automatically sends alerts to the shipper and the consignee. This real-time ETA is increasingly replacing manual status enquiries by telephone.
ATA and ATD – the actual times
Alongside ETA and ETD there are ATA (actual time of arrival) and ATD (actual time of departure) – the times that actually occurred. The difference between ETA and ATA is an important KPI for assessing the reliability of forwarders and carriers.
