摘要: 在英国标准体系下建立列车接近道口的简化模型,分析列车接近道口的运行状态,得到自动道口在不同初速度下的道口报警时间。分析得到列车接近多道口区段时影响道口报警时间的关键因素。分析含多道口双线区间的发车间隔,得到对向发车间隔的计算方式,并对模拟多道口区间列车的运行场景进行MATLAB仿真计算,得到该场景下最佳发车间隔。

关键词: 英国标准, 道口区间, 发车间隔, MATLAB仿真计算

Abstract: 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.

Key words: British railway standard, level crossing block section, departure interval, MATLAB simulation calculation
