摘　　要：传统的手工方式管理广域的、实时、海量公路资产数据已经显得无能为力,导致了公路资产的数据的快速、有效的获取和数据查询分析成为瓶颈.针对公路资产管理需求,提出一种基于GIS,GPS和多媒体等多源数据集成的公路资产管理信息系统架构.本文着重研究了公路资产数据获取及其预处理,地图匹配,并在此基础上通过对公路资产的空间信息与属性视频信息的交互式查询,从而实现公路资产信息的智能化,可视化管理.The traditional way is not competent for managing big mass and real-time highway assets data,leading to the bottleneck of gaining and analyzing data efficiently.This paper utilizes Global Positioning System(GPS),Geographic Information System(GIS),and multimedia as multi-source data,and proposes architecture of highway assets management system based on those data.We focus on the methods of multi-source data getting and prepossessing,road map matching technology to make the location information of highway as-sets to be matched to the road map,and based on those,the each other dynamic inquiry delivering space information and attribute video frequency information being in charge of the traffic control center.Thereby,intelligent and visual management of highway assets infor-mation are realized.
