| 摘 要： | 编组站是铁路枢纽的核心,是车辆集散和解编基地,线路复杂度极高。囿于编组站数量较少,国内外文献中鲜见探讨其综合选取策略与方法的文章,而大量有关道路的研究成果又不适用。本文在分析编组站结构特性和拓扑特性的基础上,首先精练出6种地图特征:断头弧、同节点弧、相似弧、网眼弧、平行弧和主干弧;提出了适合编组站综合选取的3项基本原则;然后设计了自动化处理方法;最后用实际数据测试验证了这些基本原则的合理性和方法的有效性。

| Abstract: | The railway marshalling yard is the center of railway hub, where trains are distributed and divided.Railway lines are extremely complex.Meanwhile,as there are only a limited number of marshalling yards in the world,few research articles are devoted to finding a map generalization strategy.Many existing research results on line selection are not applicable to marshalling yard.So, this paper presents a novel automated map generalization method for railway marshalling yard.First,six map patterns are extracted based on the spatial distribution and topological characteristics of marshalling yard,including broken arc,same-node arc,similar arc,mesh arc, parallel arc and main arc.Then,three basic principles suitable for map generalization and automated processing are proposed.Finally, practical data is used to validate the method.The results show that our method is highly reasonable and efficient. |
