Abstract
The intelligent transport system (ITS) has become one of the most globally researched topics with a lot of investment and development resources being dedicated into it due to its foreseen impact on the economic growth of the transport sector. Currently there are two main vehicle-to-everything (V2X) technologies, whose primary application is focused on ITS, backed up by the key players of various automotive, telecommunication and transport industries: dedicated short-range communications (DSRC) and cellular vehicle-to-everything (C-V2X), respectively based on IEEE 802.11p and 3GPP LTE/5G NR. While DSRC already has deployments, C-V2X is expected to see larger scale trails and deployments in 2020. In this work, the authors provide insight and review into two main V2X technologies, DSRC and C-V2X, their core parameters, shortcomings and limitations, and explore the need for integration of IoT-based technologies into modern ITS solutions. A comprehensive overview and analysis of currently commercially available V2X products, their sub-blocks and features is provided.
Highlights
The transport sector is one of the most important economic sectors and sources of income, both in Europe and globally
The European Union (EU) transport sector alone generates more than 9% of EU gross value added (GVA), with transport services alone representing 5% which is equal to EUR 662 billion
Being aware that the number of mobile users and data transfer amounts since 2017 have been increasing and will still be increasing until 2022 several times [11], it remains unclear whether the current mobile, cellular network infrastructure will be capable of transmitting data via C-V2X communication technology within the permissible latency
Summary
The transport sector is one of the most important economic sectors and sources of income, both in Europe and globally. The potential for urban infrastructure development is limited and, as the number of vehicles grows, the problem of traffic jams in cities will become more and more relevant For the latter reasons, these challenges will only continue to increase unless drastic new political and technological measures are taken. Being aware that the number of mobile users and data transfer amounts since 2017 have been increasing and will still be increasing until 2022 several times [11], it remains unclear whether the current mobile, cellular network infrastructure will be capable of transmitting data via C-V2X communication technology within the permissible latency For the latter reasons, it is necessary to look for DSRC and C-V2X architectural solutions that support reliable and efficient V2X connections. The final chapter concludes the presentation of the essential V2X and IoT progress that has been spotted over the recent years and summarizes suggestions for further research and technology development
