In Visibility Hub we only display ETA when we are confident that our prediction will be accurate. Prediction confidence is computed internally by our ETA model, and is high when:
Vehicle is driving (not breaking), and is moving towards the destination
Latest vehicle position is being regularly updated
Transport has correct timeslots and addresses
Assigned carrier had a high visibility index (>80%) over the last month
When our confidence is low we temporary hide ETA to avoid producing false alerts and display the warning (ETA is hidden due to low prediction accuracy), and would remove the ETA prediction for all unvisited stops. Once model's prediction accuracy increases, the warning will disappear and we will resume displaying ETA predictions.
