LiiDi2 – The digital twin for mobility paves the way for new services

Artikkelikuva: Project introduction

The (LiiDi2)  – mobility digital twin as an enabler of services project will create a model for mobility digital twins and develop new methods for data collection.

The digital twin for mobility provides a virtual representation of traffic, the infrastructure and conditions. It brings together different sources of information and opens up opportunities for new services and the development of a functional city.


The objective of the LiiDi2 project is to improve cities’ capabilities to react to and meet challenges with changes in mobility and traffic and create the prerequisites for developing mobility innovations. The project will expand the current service offering and improve the level of traffic and transport services for residents and businesses.

This will be accomplished by

  • creating a model for the digital twin of mobility
  • developing and piloting new data collection methods
  • developing and piloting an innovative procurement model
  • creating a dialogue between multiple operators
  • enabling new market potential for businesses in the sector and service
    solutions for cities in the region

Duration, partners and funding

  • The project will run from 2021 to 2023.
  • The total budget is 871,363 euros, of which Forum Virium Helsinki’s share is 588,738 euros.
