ETA prediction (ML) for ground schedule shipments

In our project, I am exploring ETA prediction through machine learning. We have ground-scheduled shipments and don't use bulk plans for planning. I also tried to do a POC on the same. But, I see Bulk is required to execute ETA prediction. 

Please let me know if someone implemented ETA Prediction through machine learning for ground schedule shipments. If yes, please share detailed information. I guess it is yet to launch for ground-scheduled shipments. 

Oracle support didn't have any clue when I raised an SR and suggested asking this question in discussion forums.
