New pruning technique speeds up public transport routing by 57%

Researchers have developed a new technique called Early Pruning to significantly speed up public transport routing algorithms like RAPTOR. This method optimizes transfer calculations by pre-sorting connections and discarding longer, less efficient routes early in the process. Early Pruning can be integrated with existing systems and has demonstrated query time reductions of up to 57% on real-world transit networks, without sacrificing the optimality of the routes found.
