| Abstract: | Combining the channel failure and data frame transition delay as well as recover behavior,a hierarchy mode of train tracking communication channel in ETCS(European Train Control System) based on the hierarchy timed coloured Petri Nets(CPN) was proposed.The influence of train speed,delay between position reports was analyzed and the responding train headway was given.Research results have significance for train headway optimization,train efficiency improvement and train running safety. |
