Survey on the Practice Hurdles in Collecting, Managing, and Sharing Transportation Infrastructure Asset Data

摘要

Transportation infrastructure asset management is a data-driven process. Great efforts have been made by state highway agencies (SHAs) in asset management in recent years. To investigate the challenges that SHAs are still facing in current practice, a web-based survey was distributed across different functional divisions of SHAs through AASHTO's Standing Committee on Highways. SHAs responded to questions about their current practice in transportation infrastructure asset data collecting, managing and sharing. The key implementation hurdles were summarized, which indicated that in current practice, the construction documentation process and the asset in-place data collection process in SHAs are two separate entities, and that this discrepancy caused data loss and duplicate data collection. Further, the survey included questions aimed at seeking the expectations from SHAs towards future improvement. To overcome the data blockage in the current practice, the paper-based data is expected to be replaced with electronic data, and a mechanism is needed to facilitate the flow of data items collected in construction documentation to asset management information systems from the long-term operation and maintenance (O&M) perspective. The results and findings are valuable in emphasizing the current practice hurdles in collecting, managing and sharing transportation infrastructure assets, as well as assisting SHAs to make efficient decisions for future research and implementation.
