Technologies and Applications for Intelligent Vehicle-infrastructure Cooperation Systems

Intelligent Vehicle-Infrastructure Collaboration Systems (i-VICS) represent the cutting-edge technology andan inevitable trend in the intelligent transportation systems (ITS) globally. It is critically developed to improve travelefficiency, optimize energy consumption, and reduce vehicle emissions, and will fundamentally change themanagement mode of traditional road transportation. Firstly, i-VICS is introduced in the paper as the common platformfor future road traffic systems. Based on it, the change of service domains for the user services in the nationalarchitecture of ITS is discussed. The latest related technologies are then investigated for the implementation of i-VICS,including technologies for multimode wireless communication, intelligent networking, information security, and systemintegration, and also for the application of i- VICS, including technologies to support the collaborative perception,swarm coordinated decision-making and control, simulation-testing validation, and connected automated driving. Withthe consideration of the long- term development of i- VICS, the contents of implementation, degree for informationsharing and synergistic functions that could be realized in different stages are presented. Furthermore, concerning thechallenge from its implementation and application, the paper points out that to obtain deep understanding, to grasp theessence, promote the experience and moderate scale of application for i-VICS can effectively address the developmentof modern intelligent transportation system. In short, the fundamental theoretical research, key technology developmentand practical system application of i- VICS will play an important role in ITS and related disciplines, like systemsengineering for transportation and science for systems.
