Abstract

For the problems of the communication delay influence on the safety location in control system, research has been done for the delay of communication with different system structures of control and length of data frame. According to numerical results, the comparison between basic access and RTS/CTS can be seen clearly. The results show that under the current condition in CBTC, the basic access could reduce the delay of communication system effectively and meanwhile improve the efficiency of driving.
