Gathering real life data, for whatever type of use, is a time consuming job. A lot of data is measured and stored in several places and different formats around the world. While a lot of it is not used, other institutions gather similar data on different locations or, worse, on the same ones. In this way, a lot of money and time is spent unnecessarily (Miska and Lint 2006). Thus, the aim of the International Traffic Database (ITDb) project is to provide traffic data to various groups (researchers, practitioners, public entities) in a format according to their particular needs, ranging from raw measurement data to statistical analysis.
