Abstract
Tracking headway time is an important target the Metro capacity. In order to meet the 150 second design capacity in the Shanghai Chongming Line long tunnel section, this article firstly analyzes the train tracking headway time under different ventilation shaft control modes. Then, it develops a simulation tool for optimizing the location of ventilation shafts in long tunnel sections. And it develops different tracking control model algorithms for train in the ventilation shaft sections. Finally, it takes the long tunnel section between Changxingdao Station and Chenjiazhen Station in the Shanghai Chongming Line as an example to demonstrate the usability of this simulation system and the reference value of simulation results.
