Abstract
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.

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;
- and
- removing 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.
A method of removing a suspected section 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, a change of occupancy status of the second block;
- determining a reference travel distance of a hypothetical vehicle in response to the change of occupancy status of the second block, the hypothetical vehicle being adapted to model occurrence of an occupancy status-changing event in the second block;
- calculating an estimated distance between the communicating vehicle and the hypothetical vehicle;
- and
- removing the suspected section from the record if the estimated distance is less than a predetermined threshold distance.
A method of removing a suspected section of a first block of a track from a record, comprising:
- determining, by a hardware processor, change of occupancy status of the first block from a vacant state to an occupied state, the first block comprising a first block boundary and a second block boundary, a communicating vehicle moving along a direction from the first block boundary to the second block boundary, and the suspected section being defined as a section of the first block between the communicating vehicle and the second block boundary;
- determining a reference travel distance of a hypothetical vehicle in response to the change of occupancy status of the first block, the hypothetical vehicle being adapted to model occurrence of an occupancy status-changing event in the first block;
- calculating an estimated distance between the communicating vehicle and the position of the hypothetical vehicle;
- and
- removing the suspected section from the record if the estimated distance is less than a predetermined threshold distance.
