To design and implement a transportation consultation process between the major cities, we provide three optimal decision strategies for passengers: (1) the shortest flight time (2), the shortest total time (3), the minimum cost (4), and the least number of transfers.
Two. Experimental requirements
(1) select the appropriate data structure storage band weight Roadmap
(2) realization of the shortest path algorithm for single source
