- Abstract
The composition of train tracking interval is analyzed in depth with comprehensively considering of various infl uencing factors, including train performance, line conditions, signal system, transportation operation. Train tracking interval is accordingly decomposed into train performance operation time, additional operation time under line conditions, additional operation time under signal system and other additional operation time. Defi nitions of each operation time and its contribution rate to train tracking interval are proposed. Taking CR400BF EMU and its operation parameters as an example, the contribution rate of each operation time to each train tracking interval is calculated using simulation calculation software, under the combination conditions of diff erent operation speeds, diff erent gradients and diff erent block section lengths. The infl uence of each factor and its combination on train tracking interval is quantitatively analyzed. Conclusion: For train interval tracking time and train passing tracking interval, the leading factor is signal system when the operation speed is low, and the leading factor is train performance when the operation speed is high. For departure tracking interval and arrival tracking interval, the leading factor is line conditions.
