Highway Engineering Information Technology Based on Spatio-temporal Big Data

Space-time big data, represented by space-space integration, combines GIS, remote sensing, tilt photography, BIM and Internet of things, and is an important driving force for the development of highway information. However, at present, China’s highway design code still adopts two-dimensional drawings as the design and delivery standards. That leads to the lack of the information management technology for large-scale highway construction based on space-time big data. In order to solve the above problems, this paper expounds the technical framework of spatio-temporal big data, which is composed of geographical modeling, geographical design, geographical monitoring and geographical control, and puts forward some key technologies such as geographical information, BIM and tilt photography, etc., the paper also introduces the experience and thinking of the application of road information technology based on BIM in the design and construction of G30 project, the advantages of applying BIM and GIS to the field of highway engineering design and construction in our country are revealed. Compared with the current highway design and construction management methods, the advantages of the proposed method are the whole process of collaborative work and the efficient control of the whole process. This laid a foundation for the further development of highway information technology and application by combining remote sensing, tilt photography and other advanced technologies.
