Resumé

In this report a complete system used to compute travel-times from GPS data is described. Two approaches to computing travel time are proposed one based on points and one based on trips. Overall both approaches gives reasonable results compared to existing manual estimated travel times. However, the trip-based approach requires more GPS data and of a higher quality than the point-based approach. The system has been completely implemented using open-source software and is in production. A detailed performance study, using a desktop PC, shows that the system can handle large data sizes and that the performance scales, for some components, linearly with the number of processor cores available. The main conclusion is that large quantity of GPS data can, with a very limited budget, used for estimating travel times, if enough GPS data is available.
