基于GIS平台的交通标线布设方案自动生成系统设计

根据道路交通标线的几何特性及其与道路几何中心线的方向关系,将交通标线归为纵向标线、横向标线及点状标线,建立了面向布设方案自动生成的交通标线数据模型,该数据模型能表述标线与路网拓扑数据的关系,并可支持标线布设方案在GIS平台的自动生成。选取珠海市部分路网区域,以前述数据模型表达标线的布设方案,运用线性参考技术,在ArcGIS平台构建自动生成系统,实现了标线的自动生成,并存入GeoDataBase中。

Study on Automatic Generating Designing Plan of Traffic Markings Based on GIS Platform

Traffic markings were divided into longitudinal markings,latitudinal markings and spot symbol markings according to their geometrical property and directional relationship between road geometrical centerlines and them. Data model oriented to automatic generating designing plan of traffic markings was built,it can describe relationship between road network data and traffic markings,and support automatic generating designing plan of traffic markings based on GIS platform. To demonstrate this research,some parts of road network region from Zhuhai city were selected and data model above was used,automatic generating system of traffic markings was built under ArcGIS platform,and then traffic markings were realized with linear reference technique,property information of traffic markings was also written in GeoDataBase.
