During the coming years, an infrastructure of vehicles with computing, communication, and accurate positioning capabilities will emerge. For example, buses in Northern Jutland and Copenhagen are already equipped with PCs, GPS receivers, and wireless communications capabilities. This project is concerned with fundamental techniques underlying the mobile services enabled by this infrastructure.

The main problem considered is how to maintain various kinds of information about a population of vehicles on a central computer, when certain guarantees have to be met while spending as few resources as possible.

For example, the project considers the server-side maintenance of the current positions of vehicles with accuracy guarantees. Resource consumption, including network traffic and server-side updates, may be reduced by being able to accurately predict the near-future movement of each vehicle.
