Analysis of Train Departure Intervals in Block Sections with Level Crossings under British Standard System.

This paper establishes a simplified model of train approach at level crossings under the British standards system. On this basis, it analyzes the running state of trains approaching level crossings, to obtain the level crossing alarm time for automatic level crossings under different initial speeds. It analyzes the key influencing factors of the level crossing alarm time for train approach in the multi-level-crossing section. It also analyzes the train departure interval in the double-track multi-level-crossing section, to obtain the calculation method of the train departure interval for train operation in opposite directions. Moreover, it performs simulation calculation using MATLAB under the simulated scenario of train operation in the multi-level crossing section, to obtain the optimal train departure interval under this simulated scenario.
