Informationization management system of highway construction is based on the data source,which determines whether application of Informationization management system succeed or not,and its key point is the accuracy,authenticity and timeliness.Meanwhile,to share and support the information between highway construction and operation,create a digital highway,we must eliminate the information fault between the project construction and operation.Aiming at information and quality fault of data source,which exist everywhere in informationization management system of highway construction now,this paper proposes two solutions:one is to introduce the on-site construction monitoring system of 3G mobile phone,which is based on the intelligent mobile communication technology,and the other is to use the electronic sand table,based on Web GIS and VR virtual technology.After their application on the Licha Highway,we have basically solved the problems existing long-term in project construction,such as loss of authenticity and lack of efficiency of data,as well as the information fault between construction and operation.
