Abstract:

As a new standard blocking format, under the premise of ensuring the safe operation of trains, Moving block can make the headway time of trains as the minimum. Around the headway time of trains under the moving block system, the calculation method of section time occupancy belt occupied by a train was presented. Then, using the overlapping method, a new headway calculation method was designed which was based on blocking time under the moving block system. Finally, several simulation experiments were designed on the visual studio platform about the factors affecting the headway time, quantitative analysis of different influence factors on the law of time headways using the calculation method of tracking headway.

Key words: moving block, tracking headway, affecting factors, blocking time, calculation method
