摘要
针对高速公路养护信息传统管理模式中空间数据的"节点-弧段"几何模型存在养护信息数据不独立、信息数据冗余,以及原有动态分段数据模型不能表达不同方向车道交通特性的差异问题。文中基于高速公路空间的线性特性以及综合车道号+里程值的定位方法,提出将动态分段技术应用于以综合车道为基本建模单元的空间数据管理模式,设计专门的养护信息系统,实现将二维坐标转换为一维相对坐标、多源数据集成组织、降低信息数据冗余及病害信息的快速定位与编辑。
For＂node-arc＂geometric model of spatial data in the traditional management system for highway maintenance information,the disadvantages are as followed：the data of maintenance information are dependent and redundancy,and the existing dynamic segmentation data model inhabits differences in the lanes characteristics of various directions.Based on the spatial linear features of highway and positioning with method of integrated lane number＋mileage value,the dynamic segmentation is applied to the spatial data management mode which is used in the integrated lane as basic modeling unit.A special maintenance information system is proposed to achieve that 2D coordinates to convert to 1D relative coordinates,organize data from different sources,reduce the redundancy and disease information positioning and editing rapidly.
