The transition to smart and sustainable cities is a key strategic objective in Europe and a United Nations Sustainable Development Goal (SDG). To achieve this, digital urban twins are an emerging area of research that can contribute to improved solutions for urban governance and decision-making in the areas of mobility, environment, energy, security and carbon reduction.

Digital twins (virtual representations of a system or object that include its history, update data in real time and use simulation, machine learning or reasoning for decision-making) offer a transformative approach to designing, managing and optimising cities in an increasingly complex and interconnected world, as recognised by the European Commission, which emphasises the integration of cutting-edge technologies for smart and sustainable cities.

A team from the Institute of New Imaging Technologies, specialised in geospatial technologies and the development of GIS (Geographic Information Systems), led by Professor of Languages and Computer Systems Joaquín Huerta, is participating in NexTCity, a project of the Horizon Europe programme of the Universidade Nova de Lisboa (coordinator), together with the Katholieke Universiteit Leuven (Belgium) and the UJI. They are all experts in the field of urban intelligence, digital twins or smart cities.

NexTCity is a project that aims to improve the field of digital twins for cities at all stages of development: data collection and integration, forecasting and simulation analysis, data visualisation and data governance. It also includes staff exchanges, workshops, summer schools and the City Digital Twin Conference, with the aim of promoting Portugal's scientific and research capacity, while disseminating knowledge to the scientific community to support the creation of new technology industries.

The project will build on existing in-house knowledge on descriptive, predictive and prescriptive analytics applied in an urban context to position NOVA IMS (Universidade Nova, NOVA Information Management School and Cidade Urban Analytics Lab) as an international reference centre in urban analytics for cities, focusing on the application of digital twin technology in the context of smart city and urban analytics.

This will be done by designing a geographical information system that will integrate data available through web services. The datasets will be sourced from the APIs (application interface) of the Lisbon Open Data Portal, which will ensure continuous updates of urban features within the LEZ digital twin. This includes data such as environmental statistics, air quality measurements, traffic counts, noise levels, energy consumption figures, 3D building models or traffic congestion data from sources such as the Waze app.

The project was launched in Lisbon in September with a first working meeting attended by the coordinators of the three universities that make up the consortium: Miguel de Castro Neto (Universidade Nova, NOVA Information Management School and Cidade Urban Analytics Lab), general coordinator of NexTCity; Joaquín Huerta (Universitat Jaume I de Castelló, Spain) and Marc Olijslagers (Katholieke Universiteit Leuven, Belgium).

Population growth will pose enormous challenges to the management of cities in the coming decades: it is predicted that by mid-century 88% of the world's population will live in an urban environment, requiring support systems that enable timely decision making and improvements in the operation, planning and management of cities.

This project is in line with one of the European Union's missions to address major societal challenges and support strategic priorities; the mission to create 100 climate-neutral smart cities by 2030. These cities, including Lisbon, should act as innovation hubs by developing best practices aimed at generating value while ensuring sustainable development and a low environmental footprint.

NexTCity (Smart Sustainable Cities Moving forward with Digital Twins) is an EU-funded project under the Horizon Europe programme with grant number 101159944.
