header image with legend: LDT TOOLBOX: data driven planning for smart cities. The EU LDT Toolbox is a set of tools that enable cities to build and use Local Digital Twins for simulation and data-driven decision-making

LOCAL DIGITAL TWIN

The Living-in.EU initiative defines a Local Digital Twin as:
¨A virtual representation of a city’s physical assets, using data, data analytics and machine learning to provide simulation models that can be updated and changed (real-time) as their physical equivalents change¨

LDT TOOLBOX DESIGN PRINCIPLES

Graphic image of LDT Toolbox principles: User-centricity, Open-source technology, Standards and regulatory compliance, Interoperability
  1. User Centricity: The Toolbox must support the diverse needs of European cities, allowing for customizable LDT configurations to meet each city’s digital maturity level

  2. Standards and regulatory compliance, interoperability: All Toolbox components must comply with relevant industry standards, EU regulations, and Living-in. EU principles to ensure consistent functionality and interoperability across EU municipalities

  3. Open-source technology: The Toolbox shall be built on collaboratively developed, non-proprietary software to ensure accessibility, adaptability and broad reuse

HOW CAN IT HELP

HOW IT WORKS

Four simple steps to enable the benefits of a Digital Twin to support your decision-making and planning processes effectively, and the owners that are responsible of each of them:

The LDT Toolbox is a suite of technological tools that will be used by different types of users, depending on the different purposes that it must fulfil, so different environments adapted to each use has been designed.
