城市交通地理信息系统数据模型设计

摘要
整合空间信息和非空间信息构建公交数据模型是城市公共交通合理规划和有效管理的基础。提出了基于地理信息系统技术的公交数据模型,该模型利用弧节点网络,并通过点、链接、多边形和记录特征来管理基础总线数据。在这种模式下,以动态方式生成和维护运输网络,可供运输设施、线路服务,具有规划、建设、管理、运营和优化功能。在此模型基础上建立的公交地理信息系统可显著提高建设水平和城市服务能力。
Constructing the data model for public transportation by integrating the spatial and the non-spatial information, is the basis of reasonable plan and effective management of urban public transport. This paper presents a transit data model based on geographic information systems(GIS) technology, which utilizes arc-node networks, and manages the foundational bus data with point, link, polygon and record features. In this model, a transport network is generated and maintained in a dynamic manner, and hence supports planning, construction, management, operation and optimization functions for transit facilities and routes, as well as day-to-day transactions. Public transportation GIS established on this model foundation will remarkably up-grade the construction level and the urban service ability.
