Abstract
The parameters that describe the urban road traffic are related to the speed evolution on certain routes. In order to make a good quality analysis is mandatory to have good quality data. That means one of the most important activity is the data acquisition, which involve the selection of the appropriate methods and devices. Using a database build in years, it was possible to compare the distribution of speed frequency for a moving observer in our city, before and after some major changes in the road network architecture.
