The Changeable Block Distance System Analysis

Telematics as a future method for improving the safety of rail transport

“…With regard to safety, the ERTMS system can contribute to the elimination of events that may cause a threat to railway traffic, such as ignoring the "stop" signal and exceeding the speed limit on a given section. The solutions used in ERTMS allow for higher speeds of rolling stock and higher capacity while maintaining a high level of security, [4], [5], [13]. The ERTMS/ETCS system can be configured to work in one of the levels [1]:…”

“…The length of block section may change in time according to the current traffic situation in the controlled section of railway line. This means that the distance between trains is changeable and its actual length is the result of processing information about position and speed of all following supervised trains in the given railway line [7], [8]. The rule of the Absolute Changeable Block Distance (CDB) A presented in the Fig.…”
