摘要
为提高城际铁路列车运行图横向稳定性,本文提出了城际铁路列车关键运行线的定量确定方法,定义了相对关键系数来衡量列车关键运行线的差异性,并运用MATLAB进行编程仿真。以沪宁城际铁路为例,按照列车关键运行线相对关键系数合理分配线间缓冲时间,得到了线间缓冲时间布局优化方案。仿真结果显示,基于列车关键运行线的线间缓冲时间布局能使城际铁路列车正点率高达99%以上,列车连带晚点传播基本得到消除,提高了城际铁路列车运行图横向稳定性与列车通过能力。
In order to improve the lateral stability of intercity railway train timetable,this paper presents a quantitative method for determining critical train lines of the intercity railway,and the relative critical coefficient is defined to measure the difference of critical train lines.In addition,take the Shanghai-Nanjing intercity railway line as an example,this paper uses MATLAB simulation to reasonably distribute the buffer time between lines according to the relative critical coefficients.The layout optimization scheme of buffer time on inter lineis obtained.The simulation result shows that the inter line buffer time distribution,based on the critical train running line,can make the intercity railway punctuality rate at least 99%,and the secondary delay transmission is more or less eliminated.The lateral stability of intercity railway train timetable and train passing capacity are improved.
