Knowledge extraction from the experimental data of the vehicle traffic volume

The problem of urban traffic is very important because of the ever-increasing growth of vehicles, which is one of the reasons for the congestion in urban areas. The article presents knowledge extraction with the use of the statistical methods. The characteristics of vehicle traffic volume are determined. The data come from an experiment carried out in Szczecin as part of the Green and Sustainable Freight Transport Systems in Cities (GRASS) project. On the basis of the data, vehicle traffic volume characteristics were calculated at selected points taking into account the type of vehicles, time of the day, day of the week and the speed of vehicles.
