摘　　要：从公交信息管理现状出发,对如何利用GIS组件MapObjects开发公交查询系统进行了研究,针对传统换乘算法不能满足公交查询系统需要的现状,重点阐述了基于换乘次数最少的最优路径改进算法的基本思想。系统选用MapObjects作为GIS二次开发组件,通用语言C#作为开发语言,数据库采用SQL Server2000,实现了GIS软件的基本功能以及公交信息查询功能。According to the status of public traffic information management, how to develop public transportation query system by GIS components MapObjects is researched. In view of tradition transfer algorithm can＇ t meet the need of public transportation query system, the emphases lays on the fundamental theory of a public transportation optimum route amelioration algorithm based on the least transfer. The system chooses MapObjects to be component of GIS secondary component, current program language----C# as development language, SQL Server2000 as background database, developed public transportation query system, basic functions of GIS software, and the fimction of public traffic information query are realized.
