From my understanding it's API sharing between companies - for example, data on trains can be crossed with data on weather or data from in-car computers can be bought and sold, or insurance companies who install black boxes to record driving behaviour can make that data available.

There are so many data sets arising from transport and I believe DOVU will make them available on a blockchain-based network so companies and individuals can do research and cross different sets for data insight. At the moment nobody shares this stuff but DOVU will help learning and this is why the government backed them in the early stage as it ticks the box for 'smart cities' agenda.

it is more for companies than individuals but the system will support individuals selling their data to the grid.
