摘要
针对空间二维坐标下存储城市公交系统数据存在的问题,文中提出了采用动态分段技术建立公交系统数据库的方法,并在该数据库的基础上实现了换乘次数最少的乘车方案。基于 ArcGIS Engine 组件和.Net 开发平台,实现了基于动态分段技术的公交查询系统,表明动态分段技术在公交查询系统中的适用性。
With regard to the problems storing spatial data of public transport with 2 dimensional coordinates, the paper introduces an approach of building the database with the tecbnique of dynamical segmentation, realizing minimum transfer times based on this database. Using ArcGIS Engine component and .Net development platform, the paper set up a public transport inquiry system with proved applicability.
