Abstract:The Internet-of-Things (IoT) is a rapidly growing area of wireless communication technology that allows devices to communicate with computers and humans via the Internet. This technology goes far beyond simply connecting devices to the internet, it creates opportunities to combine data from these devices with automated systems for the purpose of analyzing, displaying, and predicting results. The research goal of this project is to explore the current status and viability of Industrial Internet-of-Things (IIoT) technology for the purpose of asset management of transportation infrastructure or the built infrastructure distributed along the highway system in the state of Missouri. Phase 1 of this project (cmr20-011) focused on preliminary research to assess the readiness of IIoT for initial implementation on the transportation highway system (such as: bridges, pavements, retaining walls, signs, etc.). This project conducted a pilot study on a limited number of assets to evaluate the IIoT technology. Through the one year of deployment of sensors on retaining walls, crash barriers and sign structures, the project realized both successes and obstacles, leading to multiple recommendations and lessons learned to benefit future deployments. Real-time data has successfully been transmitted from IIoT sensors and is viewable via the shared dashboard. Alerts have been configured to notify personnel of triggered events, including the hit-and-run impact detected at one of the monitored crash barriers. It is recommended that future IIoT deployments consider ongoing monitoring and proactive maintenance of these devices or engage third-party contractors to reduce down-time. It is the opinion of the research team that this technology is suitable for further deployment for the purpose of asset management contingent upon the consideration of lessons learned presented in this report.
