Abstract
Nowadays, intelligent transportation systems (ITS) are getting significant attention to improve road traffic safety and efficiency. For this purpose, cellular vehicle-to-everything (C-V2X) technology supporting ITS services was initially defined by the Third Generation Partnership Project (3GPP) as part of Long Term Evolution (LTE) Rel-14 enhancements. C-V2X is considered a key technology for ITS, as it evolves from LTE-V2X to 5G New Radio V2X (NR-V2X) to fulfill specific requirements depending on C-V2X applications. This paper presents an overview of V2X technology by describing the main 3GPP’s use case categories and the physical layer design of LTE-V2X and NR-V2X. Based on the assessment of the LTE-V2X sidelink communications performance conducted by the 5G automotive association (5GAA) and using the AASHTO model, we evaluate the alert delivery reliability rate, which is assessed in terms of packet reception ratio (PRR). Finally, we highlight potential technologies that will be improved in V2X communications to enhance road safety through V2X technology.
