Internet of Vehicles (IoVs) is a expected convergence of the mobile Internet and the Internet of Things (IoT). IoVs are emerging form of IoT. 5G is the latest technology in wireless broadband. 5G based IoVs is the new form of IoVs. 5G technology hasaroused people’s attention with its promise of flexible networking. Due the increase in urban population urban traffic is increased every day. This leads toward traffic congestion and increases in the number of accidents. Different traffic management systems and technologies are developed to enhance traffic performance. 5G based IoVs are built to lessen traffic accidents, relieve congestion and reduce pollution. Different road applications like road protection, traffic flow efficiency, and infotainment are greater to enhance the performance of IoVs. In this paper, our focus is on traffic efficiency. Different architectural layers of IOVS are studied for the evaluation of traffic efficiency. We are going to survey traffic management systems that are based on 5G technologies. A detailed literature evaluation is the contribution of this paper. Finally, a tabular evaluation is given for the summarization of our literature overview.
