Mapbox Horizon, now in Beta and distributed with the Navigation SDK V2, provides predictive roadway information for drivers, such as speed limits, congestion, and custom data sets like parking availability, accessible up to 10km ahead, even without turn-by-turn navigation. It combines two components: Graph Accessor, which treats maps as a graph of roads considering rules like turn restrictions and assigns "addresses" to points of interest; and Most Probable Path, which predicts the likely route a driver will take based on traffic rules and past behaviors. This integration allows Horizon to act as a "vacuum cleaner," gathering relevant road data to enhance Advanced Driver Assistance Systems (ADAS) for safety, comfort, and efficiency by anticipating road conditions such as congestion or road slope changes. Originally intended for automotive customers, it aims to democratize predictive navigation technology previously reserved for high-end vehicles, with companies like NCS in Singapore already leveraging its capabilities. Horizon is available for iOS and Android via the Navigation SDK V2, with automakers invited to explore its potential through demos and free accounts.
