Structure of V2X-IoT framework for ITS applications.

Intelligent Transport System (ITS) has become one of the most globally researched topics. Currently there are two main vehicle-to-everything (V2X) data transfer technologies for ITS applications: Dedicated Short-Range Communications (DSRC) and Cellular Vehicle-to-Everything (C-V2X). Emerging IoT technologies can also be applied in ITS systems. In the wake of deployment of various independent technologies for V2X, the need for a framework, that concurrently supports DSRC, C-V2X and IoT technologies, arises. In this work, the authors provide insight into main V2X technologies, their regulation and frequency spectrum bands, and discuss the need for integration of IoT-based technologies into modern ITS solutions. A Structure of V2X-IoT framework for ITS research and development is proposed based on the results of the carried-out analysis.
