Prioritisation of road sections — MEL

This table makes it possible to know the hierarchical classification for each section of the track base and to easily link the sections to the track. The hierarchy of sections is divided into 5 levels: — Level 1 and 1a: hyper-structuring network (Autoroute, National Road, Metropolitan road type RNO, VRU, M700...) — Level 2: structuring network — Level 3: secondary network — Level 4: low to medium traffic agglomeration or intercommunal distribution network — Level 5: street of neighborhoods本表格可用于查询路段基础库各路段的层级分类信息，并可便捷实现路段与所属道路的关联匹配。 路段的层级体系共划分为5个层级： — 第1层级及第1a层级：超级骨干路网（hyper-structuring network），包含高速公路（Autoroute）、国道（National Road）、RNO型城市道路（Metropolitan road type RNO）、VRU、M700等类型 — 第2层级：骨干路网（structuring network） — 第3层级：次要路网（secondary network） — 第4层级：中低流量聚集区或跨社区配送路网（low to medium traffic agglomeration or intercommunal distribution network） — 第5层级：社区街巷（street of neighborhoods）
