STUDY REGARDING THE STATISTICAL MODELLING OF THE URBAN TRAFFIC FLOWS

Abstract

Traffic engineering involves the collection and analysis of large amounts of experimental data for carrying out different types of studies, which require the use of mathematical statistics as a tool of analysis. Statistics helps to determine the amount of data required to achieve a certain level of confidence in the obtained results. It is impossible to observe all vehicles passing in a section of road in a spell of time, even if it is known, another data collection will not reproduce certainly the previous situation. It does not matter how many speeds are recorded, there is always much more data are not known, so the number of vehicles observed in a section of road can be considered infinite. For these reasons for the experimental studies must be observed and measured the characteristics of a sample finite number of elements. The research paper intends to make statistical analyses of the collected data from the urban area.
