**输入数据目录**

本网络数据集为可与其他网络（即网络A与网络B）的路径进行对比的网络示例。

本数据集包含两个目录：

a) 网络C（NetworkC）
b) 网络路径（NetworkPaths）

“网络C”目录

- 本网络基于密苏里州交通部（Missouri Department of Transportation, MoDOT）2016年7月道路数据集的子集，该数据集已列入参考文献。
- 网络C包含ESRI .gdb文件NetworkCdata.gdb，其中存储了网络C的弧段与节点数据，同时附带ArcGIS ND网络分析（ArcGIS Network Analyst）配置文件。
- 要素数据集：NetworkCsub
- 网络弧段：NetworkCsub
- 网络文件：NetworkCsub_ND
- 网络节点：NetworkCsub_ND_Junctions

“网络路径”目录包含用于表示以下内容的ESRI .gdb文件：

a) 各网络中起讫点对之间的路径集合（InputPaths.gdb）

- 应用中使用的加密路径（加密步长为10米）：(Net_A_routelines; Net_B_routelines; Net_C_routelines)
- 保留原始顶点集的原始路径（未加密）：(Net_A_routes; Net_B_routes; Net_C_routes)

b) 路径的起讫点（ODNodes.gdb）

- 这些点用于生成各网络的最短路径，作为待对比的路径集
- 起点：originLocations
- 终点：destinationLocations
