有没有办法在诺基亚位置api获得公布的街道限速？

Question

Is there a way to get the posted street speed limits in nokia location api?

Is there any web based API service which provides street speed limits for the united states?

Answer 1

You will need to use the getLinkInfo endpoint from the Enterprise Routing API. . The speedLimit element returned is in m/s so multiply by 3.6 for km/h or 2.23 for mph . If the speedLimit element is missing then the national speed limit applies.

http://route.st.nlp.nokia.com/routing/6.2/getlinkinfo.json?waypoint=52.5308,13.3846&app_id= your_app_id &app_code= your_app_code

Answer 2

Since Jason answer is outdated, you should now use/migrate to Here API which is newer and faster.

• You have to use different endpoint.
• SpeedLimit is returned in m/s aswell.

You can make request with:

• GPS coordinates ( doc ):

or

• linkId ( doc )
