  • The research status of vehicular networks of rail transit both at home and abroad was analyzed from three aspects, i.e., cellular wireless access technology, non-cellular wireless access technology, and heterogeneous smart cooperative vehicular network access technology. Considering the problems of non-cellular and cellular wireless access technology, the advantages of cooperatively using heterogeneous wireless resources around rail transit for network convergence and cooperative communications were expounded. The convergence schemes of heterogeneous smart cooperative vehicular networks were discussed from the aspects of the network model and network architecture. In view of the business requirements of intelligent rail transit, the existing research on heterogeneous smart cooperative vehicular networks was systematically classified from the perspectives of reliability and resource utilization. The future development trends of heterogeneous smart cooperative vehicular networks were proposed regarding artificial intelligence, security, and cloud-edge combination. Research results show that the reliability of heterogeneous smart cooperative vehicular networks is comprised of network architecture reliability and data transmission reliability. The former mainly proposes improving reliability in the ways of redundant network architecture, vehicle-to-cloud transmission architecture, software-defined network architecture, and smart and cooperative network architecture. The latter focuses on reducing the packet loss rate in the process of transmission through three ways, i.e., multi-path transmission, network coding, and handoff algorithms. The resource utilization of heterogeneous smart cooperative vehicular networks can be divided into wireless access resource utilization and link scheduling resource utilization. The former improves the throughput and resource utilization by three methods, i.e., channel state prediction, spectrum division, and frequency shift compensation. The latter reduces the influence of heterogeneous links on data transmission and the times of data retransmission and raises the utilization of network resources mainly by scheduling algorithm, receiving and buffer algorithm, and congestion control algorithm. 6 tabs, 7 figs, 79 refs.
