A recent study in Engineering explores the potential of digital twin (DT) technology to transform road engineering across its lifecycle, from planning to demolition. Conducted by researchers from Tongji University and Harbin Institute of Technology (Shenzhen), the research reviews DT-enabling technologies such as model creation, condition sensing, and data processing, highlighting their application in optimizing infrastructure design, construction, and maintenance.
While DT technology has shown promise in integrating engineering data with environmental factors and improving resource allocation during construction, challenges remain, including a lack of standardized definitions, diverse modeling tools, and advanced data interaction techniques. The study emphasizes the need for further innovation in enabling technologies and the establishment of uniform standards to fully realize DT’s potential in enhancing efficiency, safety, and sustainability in road engineering.
Digital Twin Technology Potential in Road Engineering
Digital twin technology holds significant potential for enhancing road engineering by enabling comprehensive lifecycle management. This technology integrates virtual models with physical infrastructure, facilitating real-time monitoring, predictive maintenance, and optimized decision-making across all stages of road development.
In the planning and design phase, digital twins can synthesize engineering data with environmental factors to optimize route selection and pavement design. For instance, an urban road planning method utilizing the DT-MCDM-GIS framework was successfully implemented in Bromley, UK, demonstrating how this approach enhances project efficiency and sustainability.
During construction, digital twin technology aids in resource allocation, quality control, and progress monitoring. Providing a virtual representation of the physical structure allows for precise tracking of materials, labor, and timelines, ensuring projects stay on schedule and within budget.
Digital twins play a crucial role in operation and maintenance by continuously monitoring pavement health, managing road assets, and informing maintenance decisions. This proactive approach reduces downtime and extends infrastructure longevity, contributing to overall efficiency and safety.
Despite these advancements, challenges remain. The lack of standardized definitions and protocols for digital twin systems in road engineering hinders widespread adoption. Additionally, the diversity of tools for digital pavement modeling is limited, and improvements are needed in data acquisition and interaction technologies to achieve seamless real-time interoperability.
To address these issues, researchers recommend establishing uniform standards, developing innovative perception and data interaction techniques, optimizing development costs, and expanding lifecycle applications. By overcoming these challenges, digital twin technology can further enhance the efficiency, safety, and sustainability of road engineering projects.
