A method of removing a suspected section from a record includes obtaining an estimated distance between a communicating vehicle and a block boundary of a first block and a second block of a track. The suspected section is defined as a section of the first block between a communicating vehicle and a block boundary of the first block and the second block. An occupancy status of the second block is obtained. The suspected section is removed from the record after, for a predetermined time period, (a) the estimated distance remains less than a predetermined threshold distance and (b) the occupancy status of the second block remains a vacant state, the predetermined time period being a non-zero time period. 1. A method of removing a suspected section of track from a record , the suspected section being defined as a section of a first block of a track between a communicating vehicle and a block boundary of the first block and a second block of the track , the method comprising:determining, by a hardware processor, an estimated distance between the communicating vehicle and the block boundary;determining, by the processor, an occupancy status of the second block; andremoving the suspected section from the record after, for a predetermined time period, (a) the estimated distance remains less than a predetermined threshold distance and (b) the occupancy status of the second block remains a vacant state, the predetermined time period being a non-zero time period.2. The method of claim 1 , wherein the predetermined time period being set based upon a processing time between occurrence of an occupancy status-changing event in the second block and the receipt of the occupancy status-changing event by the processor.3. The method of claim 1 , further comprising:activating a timer after (a) the estimated distance becomes less than the predetermined threshold distance and (b) the occupancy status of the second block is the vacant state, the timer being set to expire after the ...
