Research on Construction Framework of Highway Digital Twin Model
Digital twin presents both new opportunities and challenges for the digital transformation and upgrading of highway transportation.To address the issue of constructing a smart highway digital twin model,we propose a foundational framework consisting of data acquisitionand processing,all-element model construction,model fusion,model validation and correction,application layer development,and model management.This paper investigates the methodologies for constructing a digital twin model of smart highways from four key perspectives:smart highway data perception,entity modeling of smart highway components,dynamic modeling of operational processes,and simulation of traffic flow states.Additionally,it conducts practical simulations based on the developed digital twin model.This research aims to provide technical support for the construction and further application ofsmart highway digital twin model.
