About the research
The adoption of various advanced computerized technologies such as three-dimensional (3D) modeling, LiDAR, and geographic information systems (GISs) is making a transformative change–from an analog to a digital data-based system. This has an impact on how project information is produced, exchanged, and managed throughout the lifecycle of a transportation project . With ample evidence and success stories from the vertical construction industry and some promising case study results from the highway industry, the significant improvement of data and information sharing between project participants and across various project development stages is possible with a model-based project delivery process and electronic and digital data transfer systems, which will in turn translate into increased productivity and efficiency in project delivery, accountability, and asset management.
The adoption of various advanced digital technologies has enabled a large portion of the project lifecycle data to become available in digital format. However, due to the fragmented nature of the highway industry sector, digital datasets are being archived, and managed separately. Due to this, transportation assets as a whole have not yet fully benefited from the growing amount of digital data since digital data from distinct actors are yet to be linked and fully reused.
The purpose of this research is to enhance the understanding of data and information workflow during the lifecycle of transportation assets by capturing the industry knowledge and experience and developing a business process map and a data sharing map. Through seamless exchange of data and information throughout the project lifecycle, a significant amount of effort can be saved, and high efficiency can be achieved. The research aim is to develop a guide to help professionals of state departments of transportation (DOTs) understand the digital data and information flow during the project life-cycle for various type of transportation assets including pavements, bridges, culverts, signs, guardrails,and so forth.
This project will help by identifying business processes that require data sharing during the project lifecycle and identifying data exchange requirements (specifying which data need to be shared and by whom). The project objectives will be achieved by conducting an intensive literature review, benchmarking the vertical industry, and conducting focus group discussions with industry professionals from various disciplines and phases. This project is expected to enhance the process of data and information sharing, and, consequently, help to reduce operational costs of highway assets.
