Framework for Enhancing Resilience of Cyber-Physical Operations in Connected Work Zones

Abstract: Among the various transportation management systems influenced by Vehicle-to-Everything (V2X) technologies, Smart Work Zone (SWZ) systems are particularly noteworthy for their ability to predict real-time travel times, delays, and speed fluctuations on highways. These capabilities not only reduce driver frustration but also help alleviate highway congestion and enhance safety for both motorists and workers. However, SWZ systems represent a sophisticated, interconnected network that has emerged in recent years, leveraging the seamless integration of computer, communication, and sensor technologies. Operating with minimal human oversight, this network introduces an automated framework, which in turn exposes it to potential vulnerabilities and cyber-physical security challenges.

This presentation will introduce a systematic framework for designing Cyber-Physical System (CPS)-based SWZ operations, along with an AI-enabled, data-driven paradigm to enhance the safety and resilience of connected vehicle traffic operations at critical work zones. The main topics of the presentation will address the following questions:

• How can we identify vulnerabilities in cyber-physical operations that may impact the safety and resilience of connected work zone systems?
• What strategies can be considered to prevent vulnerable functions and mitigate their impact on safety?
• How can we develop a data modeling paradigm to achieve cyber-physical vulnerability prevention or resilience under typical infrastructures and critical conditions?"
