Review on the application of freeway CVIS communication technology

Abstract

This paper mainly describes the research progress of Cooperative Vehicle Infrastructure System (CVIS) communication technology in freeway. The application status of short-range real-time communication technology and intermediate-range interactive communication technology in different scenarios of freeway CVIS are discussed respectively. This paper summarizes the existing problems in the research of CVIS communication technology from two aspects of technology application and network security. The research shows that in the future, machine learning, deep learning and other methods can be used to automatically detect network intrusion and deal with unknown attacks; In the future, the CVIS communication technology will adopt channel coding technology and encryption technology to improve the security of wireless network; With the development of 5G technology, the Internet of Vehicles(IOV) will usher in new opportunities. In the future, the freeway communication network will be a heterogeneous wireless network with multiple access networks, which can meet the application requirements in different road traffic scenarios, effectively promote the construction of freeway informatization and accelerate the construction process of smart freeway.
