从 HERE 反向地理编码 API 获取速度限制 [英] Getting Speed Limits from HERE Reverse Geocode API

问题描述

我正在使用来自 HERE 的反向地理编码端点来提取给定纬度和经度的速度限制.我在 locationattributes 参数中包含了 linkInfo 并且在结果正文中获得了速度限制，但它不再显示.

I'm using the reverse geocode endpoint from HERE to extract speed limits for a given latitude and longitude. I am including linkInfo in the locationattributes parameter and was getting speed limits in the results body but it is no longer showing up.

以下是一个端点被命中的例子:https://reverse.geocoder.api.here.com/6.2/reversegeocode.json?app_id={{app_id}}&app_code={{app_code}}&prox=40.1245292,-74.8721781,50&mode=retrieveAddresses&locationattributes=linkInfo&gen=9

Here is an example of the endpoint being hit: https://reverse.geocoder.api.here.com/6.2/reversegeocode.json?app_id={{app_id}}&app_code={{app_code}}&prox=40.1245292,-74.8721781,50&mode=retrieveAddresses&locationattributes=linkInfo&gen=9

这是从 HERE 获取限速的正确方法吗?

Is this the correct method to get speed limits from HERE?

推荐答案

Reverse Geocoder API 在响应中表示speedcategory，对应不同的限速范围，可以参考如下:

Reverse Geocoder API represents speedcategory in the response, which corresponds to different ranges of speed limit, that can be referred from below :

LinkInfo: { FunctionalClass: 5, TravelDirection: [ "NW", "SE" ], SpeedCategory: "SC6", LinkFlags: [ "Paved" ], AccessFlags: [ "Automobiles", "Motorcycles", "Buses", "Taxis", "Carpools", "Pedestrians", "Trucks", "Deliveries", "EmergencyVehicle", "ThroughTraffic" ] }
