基于状态矩阵的铁路枢纽列流图编制方法

针对铁路枢纽网络结构复杂、列流图绘制工作难度大的特点，研究铁路枢纽列流图的自动编制算法. 根据铁路枢纽内车站连接方向多，列流线在站内交错衔接疏解困难的特点，为车站接入点引入状态矩阵，利用状态变量记录列流线在车站区域的分布状态. 以列车类型作为一级排序，相同类型按列流径路从长到短的次序铺画列流线，借助指示线段实现列流量的标注. 采用所提算法开发了枢纽列流图编制软件，基于枢纽网络图和列车流矩阵，通过人机交互定义车站及连接线布局，实现列流线的快速编制与信息标注. 通过实例证明了算法的有效性和可行性.

Train Flow Diagram Generation Based on State Matrix in Railway Junction

Aiming at the characteristics of the complex structure of railway junction and the difficult drawing process of train flow diagram, this paper study on the automatic generation of train flow diagram for railway junction. There are more connections to railway junction station. Train flow lines are difficult to settle in the station area. State matrix is introduced and state variables are used to record the distribution of the train flow lines in the station area. Train type is the primary sort and train flow is generated in the order of path length from long to short. Annotation of train flow is achieved with indicated lines. Software system is developed to implement the algorithms. Train flow diagram is automatic generated with annotation based on the junction net, train flow matrix, the station layout and their links. The example shows the effectiveness and feasibility of the algorithms and software.
