【正文】 acing to the development of portable puter or even more perfect aspect. As a result of the lowprice and highquality of the handset, it has bee the best choice that the people obtain each kind of information service in life.In our country, along with urbanized fast development, city bus system also rapidly expands, and even bees more plex. So, finding city bus route bees more difficult. Presently, the plex city bus system causes the condition which the users often are confused, which brings many inconvenient to people, but handset city bus inquiry system is also based on this background. Firstly, the author investigates the city bus system, provides “the Algorithm based on the stand priority and the next linking matrix” and “the Algorithm based on upward and downward matrix”. Secondly, these Algorithms are transplanted to the handset by J2ME, which can provide the inquiry for city bus at any time and any where by the aid of to the wireless Inter. Finally, through testing and analyzing, it confirms this system is some feasibility and practical value.Key words: City Bus Inquiry。 City Bus Exchanging Algorithm。 Wireless Inter目 錄論文總頁數(shù)：27 頁1 引言
