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. AI

IMPACT Improves efficiency of transit routing algorithms, potentially leading to better user experiences and reduced computational costs.

    Early Pruning for Public Transport Routing

    arXiv:2603.12592v4 Announce Type: replace-cross Abstract: Routing algorithms for public transport, particularly the widely used RAPTOR and its variants, often face performance bottlenecks during the transfer relaxation phase, especially on dense transfer graphs, when supporting u…
