Industrial IoT (IIoT) is an important carrier of intelligence in road infrastructure systems, which promotes automation and safety in transportation flow and the development of new technology needs to match the corresponding agents. The goal is to implement digital twins in road infrastructure to improve public safety and security remotely in real-time, as well as train the infrastructure for future full self-automation systems. the paper integrates the concept of a digital twin, adopts the learning and perception model of virtual space, and studies the key technologies required for connecting to the physical space of system infrastructure. The main purpose of this paper is to study high automation and intelligent control through the data center, from planning and construction to maintenance and optimization by virtual space. collecting data via local sensors in physical space and sharing it with virtual space via wireless gateway connectivity such as 5G technology, WIFI, etc. Cloud servers are used for supporting digital models and mobile applications that help to visualize data and information processes for end users.
