Stockholm Virtual City

This project aims to revolutionize the way cities are managed using AI, some taxis and the smartphone in your pocket.

The world is becoming urbanized. People are moving from rural to urban centers at a rate of 1.3 million per week. As a result, the complexity of managing the city and its infrastructure is increasing dramatically. Key assets (bridges, tunnels, and roads), on-going projects (road works, construction sites) and evolving situations (crowds, traffic, parking, and crime) all need to be managed. Problems are compounded by climate change and life-quality concerns. As a result, there is a growing need for new solutions to make cities more sustainable and liveable.

The first crucial step to addressing many of these problems is obtaining timely, relevant and actionable data about the urban environment. Data enables a more complete understanding of the city. This understanding drives better decisions and means resources can be prioritized. Data from different sources can be combined to generate "digital twins": virtual representations of the urban environment that can be used to analyse, predict and control what is happening - all for the benefit of the citizens. Using digital twins, problems can be detected quickly and then promptly solved; given sufficient data, some can even be anticipated.

The objective of the Sthlm Virtual City project is to address the need for timely, relevant and actionable data. The consortium, composed of Stockholm Stad, Univrses AB, and Taxi Stockholm, will attach smartphones to a fleet of taxis from Taxi Stockholm. The smartphones will be loaded with Univrses’ perception software, 3DAI™ Engine. This software, originally developed to give autonomous cars the ability to make sense of their surroundings, consists of computer vision and AI components. The software processes images from the smartphone camera to detect and map urban features. Stockholm Stad can use this data to manage the infrastructure in Stockholm in a smarter way. The consortium is building a pioneering system that can update a digital twin of Stockholm in real-time. It will revolutionise the way cities are run by delivering recent and accurate data to enable better decisions to be made.

Within the Sthlm Virtual City project, clear objectives have been defined. These objectives have been selected because they include novel scientific contributions and will be enablers of future research. Achieving them will also deliver solutions to practical problems.
