1. A method comprising:
- (a) receiving with a processing device and from a GPS transmitter a location along a route between a first fixed site and a destination, said first fixed site proximate an AEI reader and respectively associated with said destination by a statistically calculated parameter comprising an estimated time of travel to said destination, calculated based on a probability distribution of respective historical travel times of a population of rail cars between said first fixed site and said destination; and
(b) modifying with the processing device the estimated time of travel based upon the received location by filtering said probability distribution.

7. A method of automatically modifying a statistical database stored on a computer-readable medium and operatively connected to a processing device, said statistical database respectively associating actual arrival times of each of a plurality of railroad freight cars at a destination with a location representative of an area along a route of travel of the plurality of railroad freight cars, using respectively received first time information sent from a one of the plurality of railroad freight cars while present in the area and second time information received at the arrival at the destination, said method comprising:
-
(a) receiving with the processing device, first time information for a respective one of the plurality of railroad freight cars and the processing device associating that respective first time information with second time information received for the respective one of the plurality of railroad freight cars when it arrives at the destination; (b) repeating step (a) for a plurality of respective ones of the plurality of railroad freight cars sending respective first time information within the area; (c) subsequently subdividing, with the processing device, the area along the route of travel into a plurality of new sub-areas, each new sub-area represented by a location within the respective new sub-area to be associated in the database with actual arrival times of the plurality of railroad freight cars at the destination; and (d) repeating steps (a) to (c) with respect to each new, subdivided sub-area. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
