Method of removing suspected section of track background

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.
