Abstract
The models of RBC (Radio Block Center) handover are established by using Petri Nets for high-speed train operation across the boundary of RBCs. The safety and rationality of RBC handover protocols are analyzed and verified in the period of high-speed train crossing the RBC handover area. Based on the theory of stochastic processes, it is revealed that the protocol B of RBC handover, as a redundant alternative, can ensure the safety of train operation in case of the protocol A failure to work properly, but reduces the efficiency of RBC handover with a result of a negative impact on the efficiency of train operation. With the increase of train speed, the reliability of RBC handover will go down. Consideration should be given to the increase of the overlapping coverage areas between the adjacent RBCs, radio-field strength and the time margin of train headway.
