Smart Aarhus proposes a new way of organizing efforts to find effective and sustainable solutions to the challenges faced by many cities today. Through collaboration between the public and the private sector, citizens, the business community, and knowledge institutions, Smart Aarhus offers a platform for everyone, who wants to make use the opportunities of digitalization across sectors and hierarchies. Smart Aarhus involves citizens in the development of projects like in the project Digital Neighbourhood, where the traditional communication model is flipped upside-down, and issues raised by citizens form the basis of new city initiatives. Smart Aarhus favours sustainable solutions as seen in the project RADICAL, where a digital chip for bicycles makes traffic lights turn green and helps cyclists to an easy passage through the city.
