摘要
Mobile information services will play an important role in our future work and private life. Enabling mobility in urban and populous areas needs novel techniques for individual traffic planning, However, though there already are WAP-based traffic systems featuring route planning, their usability is not often universal. We presents a SMS-based urban public traffic information system (SMS-UPTS) offering exact transfer query service and supporting most mobile devices. The SMS-UPTS makes use of bus station library model and least transfer path search algorithm. The least transfer path search algorithm is consisted of direct reach path search algorithm and least transfer converse search algorithm(CS-LT). Bus station library model improves veracity of Chinese parse word algorithm and flexibility of traffic information system, and direct reach path search algorithm can immediately get paths whose bus stations are on the same line, and CS-LT algorithm is based on point to point least transfer algorithm(P2P-LT) which makes use of adjacent and reachable matrixes, it greatly improves transfer algorithm performance. And the implementation results show that the performance of P2P-LS algorithm is better than Dijkstra algorithm and the SMS-UPTS has good efficiency.
