基于GIS的城市道路项目库建设与空间决策支持分析

摘要

Along with the accelerating of city process ,traffic construction is in the increasingly important position in the development of city ,in order to avoid the blindness of road infrastructure construction .In this paper we put forward basic process and methods for building the road infrastructure project library .Combined with the geographic information system technology ,we established the spatial database of roads ,and realized the functions including statistical analysis on conventional indexes of roads and the automatic calculation of removal ,and other functions of spatial analysis ,provide ef-fective technical support for the scientific decision-making on road infrastructure projects of city .%随着城市化进程的加快，城市道路交通建设在城市发展中的地位越来越重要，为避免道路基础设施建设的盲目性，本文提出了建立道路基础设施项目库的基本流程与方法，并结合地理信息系统技术，建立了道路空间数据库，实现了包括道路常规指标统计分析以及拆迁量自动计算等方面的空间分析功能，为城市道路基础设施项目的科学决策提供了有效技术支撑。
