Technologies for transportation infrastructure and network digitalization
| Functional technologies | Modeling/expression objects | Modeling/expressing content | Modeling/expression purpose |
|---|---|---|---|
| Infrastructure digital modeling | The key physical components of infrastructure (facilities of carrying, control, induction, protection, auxiliary) and natural environment | Structured information model and digital expression for the infrastructure and its physical components | Form a strictly mapped and operational digital mirror of the infrastructure and its physical components |
| Infrastructure state expression and enhancement | Structural state, performance state and service state of the infrastructure physical components | The generation, digitization expression and embedding models for the infrastructure state | Form an accessible, understandable and computable digital model of the infrastructure |
| Network digital modeling | Components of the network and the corresponding spatial relationships | Digital model and expression of the network functions, grades, right-of-way and their spatial relationships | Form an accessible, understandable and computable digital model of the network |
| Network state expression and enhancement | Structural state, performance state and service state of the network | The generation, digitization expression and embedding models for the components and network state | Each component of the road network and the road network model accessible, understandable, computable |
| Carrier-road-network-environment symbiosis expression and digital | An integrated model reflecting the spatiotemporal symbiosis relationships among the carrier, flow, infrastructure, network and environment | Integrated model and digital expression of the symbiotic relationship among the carrier, flow, infrastructure, network and environment | Form an integrated expression and operational digital space for the static and dynamic relationship among the components of the ATS |
