I use HERE MAP REST API to get the speed limit.
In response, I can see JSON key: value-VEHICLE_TYPES:1023
What does 1023
mean? How can I know it is a track, sedan, etc?
You can check this by this request-
http://pde.cit.api.here.com/1/doc/layer.html?region=APAC&release=19146&layer=LINK_ATTRIBUTE_FC1&app_id=xxx&app_code=yyy
It is a bitmask (sum of values), e.g. 1 = cars, 32 = trucks, 33 = 32 + 1 = cars and trucks
