HERE 地图属性 API 8 - 车道级别详细信息（宽度/数量）/道路宽度答案

【问题标题】：HERE Map Attributes API 8 - Lane level details (width/number) / Road widthHERE 地图属性 API 8 - 车道级别详细信息（宽度/数量）/道路宽度
【发布时间】：2022-12-16 22:50:57
【问题描述】：

您好，我正在使用最新的 HERE Map Attributes API 8，并且想知道道路宽度（如果是多车道，则为车道宽度）。是否可以通过任何 HERE API 获取它？

我也使用路由 API，但它不提供车道详细信息。

感谢任何帮助和支持。非常感谢

关于这个文档https://demo.support.here.com/pde/layer?region=WEU&release=latest&url_root=pde.api.here.com&layer=LANE_FC2 仅当宽度不同于特定国家/地区的默认值 [厘米] 时才提供宽度

一般来说，道路宽度应该是国家特定的默认值。否则你需要高清（高清）地图。

在地图属性图层中，您可以在https://demo.support.here.com/pde/attributes?region=WEU&release=latest&url_root=pde.api.here.com 上搜索“宽度”

这是 curl 示例请求如何沿路线获取地图属性：
