Cooperative Vehicle-Infrastructure System Use Case Design for Smart Highway

With the rapid development of smart highway construction in domestic and foreign transportation systems, an increasingly number of countries have begun to explore and improve the deployment and development of cooperative vehicle-infrastructure system in smart highway. According to China’s “New-Generation National Traffic Control Network and Smart Highway Pilots Project”, it is significant to enhance traffic safety, efficiency and capacity. However, there is difficulty in the cooperative vehicle-infrastructure use case design. Based on the full analysis of the development status at home and abroad and the analysis of actual engineering needs, this paper came up with the architecture of cooperative vehicle-infrastructure system based on edge computing technology, combined with the current smart highway demonstration project. After feature, demand and policy analysis of the smart highway project, this paper put forward the cooperative vehicle-infrastructure use case design. The use cases are feasible and practical in Jilin and Zhejiang province. The use case design and analysis have significant guiding role for the research and development and engineering implementation of the smart highway cooperative vehicle-infrastructure system in China.
