Smart and efficient ways to construct, maintain and decommission with zero emissions with transport infrastructure.

CIRCUIT的总体目标是开发一种由数字解决方案和指导方针支持的整体方法，以促进在整个建筑供应/价值链中引入创新工程实践。可持续弹性和智能交通基础设施，以及更广泛地部署绿色公共采购和创新采购。这将通过以下方式实现：1 .开发和部署一个创新的开源数字平台（具有先进的循环分析和供应链/价值链匹配工具），与传统的工程/设计（BIM, digital Twinm LCC， LCA）和交通模拟工具互操作；2。引入模块化解决方案、生态设计和再利用概念作为传统设计的替代方案；3。最大限度地利用生物基、二级原材料（SRM）和二级结构元件（SCE）作为传统材料的替代品；包括在交通基础设施设计和路线规划的决策过程中，来自更新的交通模拟工具的信息，以减少事故、事故、拥堵和自动驾驶汽车的未来场景)。循环、智能、弹性和可持续交通的新元素和新技术将被纳入设计过程，以促进基础设施升级，并快速适应智能交通和运营。CIRCUIT还将通过挖掘数字化、循环利用、再利用和能源这四大战略支柱的潜力，提供知识和技术解决方案。不同的技术将在每个支柱中得到验证，以提供适合不同交通方式、城市和城市间环境以及基础设施生命周期不同阶段的整体方法。

The overall objective of CIRCUIT is to develop a holistic approach supported by digital solutions and guidelines to foster the introduction of innovative engineering practices in the whole construction supply/value chain to foster The overall objective of CIRCUIT is to develop a holistic approach supported by digital solutions and guidelines to foster the introduction of innovative engineering practices in the whole construction supply/value chain enabling circular, sustainable resilient and smart transport infrastructure and a wider deployment of Green Public and Innovation Procurement. This will be achieved by: i. developing and deploying an innovative open-source digital platform (with advanced Circularity analytics and Supply/value chain matchmaking tools) interoperable with traditional engineering/ design (BIM, Digital Twinm LCC, LCA) and traffic simulation tools; ii. introducing modular solutions, ecodesign and reusing concepts as alternative to traditional designs; iii. maximizing the use of biobased, Secondary Raw Materials (SRM) and Secondary Construction Elements (SCE) as alternative to traditional ones; iv. including in the decision making process of transport infrastructures design and route planning, information from updated traffic simulation tools to reduce incidents, accidents, congestion and future scenarios with autonomous vehicles). New elements and technologies for Circular, Smart, Resilient and Sustainable transport will be included in the design process to facilitate infrastructures upgrading and a quick adaptation to smart mobility and operations. CIRCUIT will also provide knowledge and technicalsolutions by exploiting the potential of fourstrategic pillars: Digitalisation, Recycle, Reuse and Energy. Different technologies will be validated in each of the pillars to deliver a holistic approach suitable for different transport modes, the urban and interurban environment, and the different stages of the life cycle of infrastructures.
