基于GIS矢量数据结构的公交数据模型的实现

The implementation of public transport data model based on GIS vector data structure

为了给乘坐公交出行的人们提供准确且有效率的最优乘车路线,在GIS矢量数据结构的基础之上,对公交数据的模型从其公交网空间位置以及关系网方面进行了分析和研究。对常用的公交规划软件的公交模型数据库进行分析,并对基于GIS矢量数据结构的公交数据模型空间数据采集方式进行了改进,以达到最小换乘次数和最小途经站数。该模型能够实现公交模型数据库的快速创建,且维护效率高,为我国公交网络系统模块的反馈机制提供了多种规划方案和技术支持。

In order to provide the accurate and efficient optimal route for the people of bus travel,this paper makes a study and analysis to bus data model on the basis of GIS vector data structure from the bus network space location and network.The bus model database on commonly used public transport planning software has been analyzed;the space data acquisition method on bus data model based on GIS vector data structure has been improved in order to achieve minimum transfer times and minimum via stops.The model used in this paper can realize the quick creation on bus model database,high efficiency in maintaining,and provide a variety of plannings and technical supports for the feedback mechanism of public transport network system module in China.
