Shortest Paths in Networks
... H. Bast et al perform Dijkstra searches from a random sample of source stations and choose as hubs stations those that are on the the largest number of shortest paths. They report a time of 10ms for station-to-station query for a North America public transportation network consisting of 338K station ...
