A Survey of Pedestrian to Infrastructure Communication System for Pedestrian Safety: System Components and Design Challenges

As urbanization continues to grow and smart cities are imagined, intelligent transportation systems (ITS) have become increasingly important as a solution to traffic congestion. While ITS focuses on vehicles, pedestrians are important road users who contribute a significant role in influencing traffic, transportation infrastructure, and the design of vehicles, However, roadside assistance is less studied than vehicular. In this paper, we discuss pedestrian-to-infrastructure (P2I) communication, which is an important aspect of ITS that can enhance safety, efficiency, and convenience for pedestrians. Furthermore, P2I systems are examined in terms of their requirements and components, as well as in terms of their potential benefits for safety and mobility issues. Finally, the paper identifies potential future directions for research on pedestrian-to-infrastructure communication in ITS. Providing a comprehensive overview of the current state of research on pedestrian-to-infrastructure communication in ITS, this review highlights the key research areas for the future.
