  • Patent number: 12175871
    Abstract: A computer system can determine historical interval data of a freight operator from completed freight service requests associated with the freight operator. Additionally, while the freight operator is fulfilling a current freight service request, the computer system can determine at least a first likely downtime interval for a non-operating activity of the freight operator prior to the freight operator arriving at a pickup location or a destination location of the current freight service request, based on the historical interval data. Also, the computer system can determine an estimated arrival time for the freight operator to arrive at the pickup location or the destination location of the current freight service request, based at least in part on the first likely down time interval. Moreover, the computer system can update a record associated with the freight operator to reflect the estimated arrival time.
