They address the problem of finding the shortest path in a large-scale system by partitioning the graph and precomputing the best path within each partition. They consider traffic conditions and integrate historical speed data with real-time speed information to determine the fastest route. Map matching helps in connecting GPS signals to specific road segments. Machine learning models like Gradient Boosted Decision Trees, Random Forest, Neural Networks, and KNN are used to provide reliable ETA predictions. ## Full article daily.dev links to this article rather than hosting it.
