一直在努力将 TMC 位置代码映射到 GPS 坐标，以获取来自 Here API 的交通流数据
https://developer.here.com/documentation/location-library/dev_guide/docs/location-referencing-tmc.html
我可以在这里看到它可能是可能的来自 Java - 有谁知道直接（API 密钥，而不是应用程序代码）API URL？互联网上似乎找不到澳大利亚的 TMC 表。
或者，有谁知道为什么在指定形状位置参数时，它在流 API 上没有那么多结果？
Been struggling to map TMC location codes to GPS coordinates for traffic flow data from the Here API
https://developer.here.com/documentation/location-library/dev_guide/docs/location-referencing-tmc.html
I can see here it might be possible from Java - does anyone know the direct (API key, not app code) API URL? The TMC tables for Australia do not seem to be available on the internet.
Alternatively does anyone know why when specifying shape location params instead, it doesn't have nearly as many results on the flow API?

如何获取澳大利亚的 TMC 表可在此处 https://demo.support.here.com/pde/layer?region=AUS&release=latest&url_root=pde.api.here.com&layer=LINK_TMC_FC3
请搜索所有 LINK_TMC 层 FC1 -FC5 上 https://demo. support.here.com/pde/layers?region=AUS&release=latest&url_root=pde.api.here.com
在这里您可以找到 TMC 代码的描述： 以逗号分隔的 TMC 点位置列表，指向此链接所引导的病房。格式：
国家标识符（1 个字母）、位置表编号 (1...99)、TMC 路径方向 (+-PN)、点位置编号 (1...65535)、链路上的行驶方向（F=来自参考节点，T =到参考节点）
示例：D1+10863F
如何获取沿路线的 LINK_TMC 图块，请查看此示例：https://demo.support.here.com/examples/v3.1/map_attributes_along_route
