Electronic Horizon Launches
Mapbox Horizon (Beta) now distributed with the Navigation SDK V2, predictively delivering drivers relevant roadway information like speed limits, incidents, congestion, or developer defined custom data sets such as parking spot availability. This data can be static (always present on the map) - speed limits, tunnels, bridges, names of intersecting streets, road class or average speed.
