As advanced technologies are adopted in the transportation industry, it is important to investigate how they can be integrated and better utilized to facilitate the success of public transportation agencies. It is also important to devise efficient ways to address the considerable amount of digital data created as these technologies are used. A newly introduced concept – Civil Integrated Management (CIM) – has potential for addressing these issues, because it involves collection, organization, and managed accessibility of accurate data and information throughout the transportation asset lifecycle. CIM is also expected to facilitate the use of various advanced technologies, so the purpose of this dissertation is to further explore the concept of CIM and investigate how it can be implemented to assist with transportation projects and programs.
After initial preparation (i.e., conducting literature reviews, consulting with experts, developing questionnaires, and identifying target agencies), two weeks of on-site visits were conducted with seven state transportation agencies to document their insights and practices associated with the CIM concept. Coding strategies were used to analyze the field notes collected from the presentations provided by host agencies and discussions throughout the visits. To further investigate one of the CIM enabling technologies – light detection and ranging (LiDAR), a web-based survey was disseminated to 28 LiDAR professionals; it produced 15 responses. Five phone interviews were also conducted using the Delphi method to develop a LiDAR data utilization workflow for 3D modeling. To investigate another CIM enabling technology – an electronic document management (EDM) system, important data related to EDM practices were extracted from field notes obtained from the CIM on-site visits. Meanwhile, follow-up interviews were conducted with the four transportation agencies identified as leading agencies with respect to EDM, and a video interview was conducted with one additional construction company involved with enterprise-level EDM implementation.
As pioneering research on CIM, the results of this dissertation provide transportation agencies and other researchers with an essential roadmap for implementing and refining the CIM concept. The findings and recommendations listed in this dissertation are also expected to assist transportation agencies in better utilizing and integrating various CIM-related technologies into their transportation projects and programs.
