Digital twin technology: Transforming road engineering and its lifecycle applications
2025-03-02
(Press-News.org)
A recent study published in the journal Engineering delves into the potential of digital twin (DT) technology in revolutionizing road engineering and its lifecycle applications. As road infrastructure worldwide faces the challenge of digitalization, DT has emerged as a promising solution.
The research, conducted by a team of scholars from Tongji University and Harbin Institute of Technology (Shenzhen), systematically reviews DT-enabling technologies, including model creation, condition sensing, data processing, and interaction. The development of DT in road engineering has been rapid, but it still has a long way to go. Current research mainly focuses on data perception and virtual model creation, while real-time data processing and the interaction between physical and virtual models need more exploration.
DT in road engineering has found applications across all lifecycle phases, from planning and design to demolition and reconstruction. In the planning and design stage, DT can integrate engineering data with environmental conditions, optimizing route selection and pavement design. For example, an urban road planning method based on the DT-MCDM-GIS framework (MCDM refers to multi-criterial decision making, and GIS refers to geographic information system) has been successfully applied in Bromley, UK. During construction, DT technology helps with resource allocation, quality control, and progress monitoring. In operation and maintenance, it plays a crucial role in monitoring pavement health, managing road assets, and making maintenance decisions. However, DT applications in the demolition and reconstruction phase are currently limited.
Despite its potential, DT technology in road engineering faces several challenges. There is a lack of a unified understanding and standard in the industry. Different studies interpret DT differently, and there are no specific standards for building DT systems in road engineering. Additionally, the enabling technologies need further innovation. For instance, the tools for digital pavement modeling lack diversity, and more efforts are required to integrate surface and internal models. Data acquisition and interaction technologies also need improvement, such as better data fusion and real-time interoperability.
The researchers propose that future efforts should be directed towards establishing uniform standards, developing innovative perception and data interaction techniques, optimizing development costs, and expanding the scope of lifecycle applications. With these efforts, DT technology is expected to bring more benefits to road engineering, improving its efficiency, safety, and sustainability. This research provides a comprehensive overview of DT technology in road engineering, offering valuable insights for future research and development in this field.

Tokyo, Japan – A team led by a member of Tokyo Metropolitan University have made advances in the search for dark matter, observing galaxies using new spectrographic technology and the Magellan Clay Telescope. With a mere 4 hours of observations, precise measurements in the infrared range have set new limits on the lifetime of dark matter. Their findings highlight the crucial utility of their technology and extend the search to less explored parts of the spectrum.
Over the past century, cosmologists have grappled with an apparent inconsistency in what they saw in the universe. Observations of the rotation of galaxies, for example, imply that there is a lot of mass out ...

In the race to meet the growing global demand for lithium — a critical component in batteries for electric vehicles — a team of researchers from Rice University’s Elimelech lab has developed a breakthrough lithium extraction method that could reshape the industry.
In their study published in Science Advances, the researchers demonstrated near-perfect lithium selectivity by repurposing solid-state electrolytes (SSEs) as membrane materials for aqueous lithium extraction. While originally designed for the rapid conduction of lithium ions in solid-state batteries — where there are no other ions or liquid solvents — the highly ordered and confined structure ...

American Board of Cardiovascular Medicine Chair Jeffrey Kuvin, MD, issued the following statement in response to the American Board of Medical Specialties denial of an independent board for cardiology:
“We are deeply disappointed with the American Board of Medical Specialties’ decision not to approve the American Board of Cardiovascular Medicine as a new, independent board for cardiology.
The decision ignores the evolution of cardiovascular medicine into its own distinct medical specialty, separate from the field of internal medicine, requiring its own set of knowledge, skills, and competencies to sustain professional excellence and effectively ...

Neuroblastoma is a solid tumor that occurs in children. When high-risk, the disease has a poor prognosis. Decades ago, adding the drug retinoic acid to neuroblastoma treatment increased survival by 10-15%. However, this effect was only evident in post-chemotherapy consolidation after bulky primary tumors had largely been eliminated. Why retinoic acid is effective in this setting but not against primary tumors, has been speculated about for nearly 50 years. St. Jude Children’s Research Hospital scientists resolved the mystery in a new study, showing retinoic acid uses a novel mechanism to kill metastasized neuroblastoma. The drug “hijacks” ...

COLUMBUS, Ohio – Novel technology intends to redefine the virtual reality experience by expanding to incorporate a new sensory connection: taste.
The interface, dubbed ‘e-Taste’, uses a combination of sensors and wireless chemical dispensers to facilitate the remote perception of taste – what scientists call gustation. These sensors are attuned to recognize molecules like glucose and glutamate — chemicals that represent the five basic tastes of sweet, sour, salty, bitter, and umami. Once captured via an electrical signal, that data is wirelessly passed to a remote device for replication.
