Engineers and architects have long built models to see their next big creation and iron out problems before construction starts. Innovate UK's Transport Systems Catapult is taking this idea to a new level: using big data and virtual reality to model entire cities to gauge the impact of future changes. The "Manchester Table" is an interactive map of the city below which sit layers of data about road, rail and tram networks. The system connects everything together, and calculates how flows of people might change in response to road closures, park-and-ride schemes or even innovations like electric bikes and cars.
