Abstract
The digitalization of road engineering faces problems such as weak digital foundation,incomplete information acquisition methods,insufficient data sharing,unbalanced development,and insufficient business collaboration.Modern digital technologies,such as big data,cloud platforms,and mobile edge computing networks,can be integrated into the entire process of road design,construction,maintenance,and operation.An important strategy is to improve the levels of informatization and digitalization in the road engineering field and to empower the high-quality development of transportation.Based on this,digital technologies in the processes of smart road design,construction,maintenance,and operation were reviewed.The applications and advantages of digital technology in the process of smart road design,including road surveys,roadbeds,and pavement design,were summarized.The current research status of digital technology in road construction was summarized,mainly involving the intelligent control and precise management of various procedures in roadbeds and pavement construction.Strategies that use digital technology to improve vehicle-road coordination level,traffic management efficiency,and road traffic efficiency were introduced.Methods for improving road condition measurement efficiency and pavement maintenance strategies were presented to realize digitalization updates during road maintenance procedures.The development conditions and trends of digital technology applied to smart road design,construction,maintenance,and operation were summarized from multiple perspectives.Related work could provide guidance and suggestions for improving the intelligence level of road design,construction,maintenance,and operation and promote the high-quality development of the transportation industry.
