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.
