General traffic measurements are carried out to determine basic traffic characteristics on voivodeship roads and national roads. The basic measure obtained during these measurements is annual average daily traffic. This is the number of vehicles that have passed over a specified point of a road section within a 24-h period on average within one year. For voivodeship roads, average daily traffic, average daily evening traffic and average daily night traffic are also determined. In the case of national roads, average daily summer traffic and average daily winter traffic are determined. The article presents a comparison of the characteristics for national roads in the Silesian Voivodeship and for national roads in Poland in the period 2000-2015.

Tools for counting traffic are not only used to obtain information about traffic conditions and necessary data in order to design new transport system infrastructure. They primarily allow for the assessment of road users’ communication needs, as well as their dynamic mobility in the transport network of the analysis area. In these aspects, general traffic measurements (GTM), which, since 1965, have been performed in Poland every five years, are extremely helpful. The article presents the results of a detailed analysis of the data derived from the GTM conducted in the period 2005-2015 on voivodeship roads. The analysis was carried out using results from the West Pomeranian Voivodeship.

One of the basic parameters which describes road traffic is Annual Average Daily Traffic (AADT). Its accurate determination is possible only on the basis of data from the continuous measurement of traffic. However, such data for most road sections is unavailable, so AADT must be determined on the basis of short periods of random measurements. This article presents different methods of estimating AADT on the basis of daily traffic (VOL), and includes the traditional Factor Approach, developed Regression Models and Artificial Neural Network models. As explanatory variables, quantitative variables (VOL and the share of heavy vehicles) as well as qualitative variables (day of the week, month, level of AADT, the cross-section, road class, nature of the area, spatial linking, region of Poland and the nature of traffic patterns) were used. Based on comparisons of the presented methods, the Factor Approach was identified as the most useful.

Jednym z podstawowych parametrów opisujących ruch drogowy jest Średni Dobowy Ruch w roku (SDR). Jest on wykorzystywany do różnych celów między innymi do projektowania i planowania rozwiązań drogowych, obliczania hałasu drogowego czy do studiów wypadkowości. Jego nieprawidłowe oszacowanie i prognozowanie może prowadzić do licznych błędów, przykładowo do niewłaściwego doboru typów skrzyżowań i niewłaściwego ich projektowania czy do przeciążenia tras projektowanych na natężenie ruchu mniejsze niż to, które rzeczywiście może się pojawić. Uzyskanie dokładnych i wiarygodnych wielkości SDR możliwe jest jedynie na podstawie danych pochodzących z ciągłych automatycznych pomiarów ruchu. Niestety z większości odcinków drogowych nie ma takich danych, więc SDR musi być wyznaczany w oparciu o krótkie okresy wyrywkowych pomiarów. W tym celu najczęściej stosuje się metodę wskaźnikową.
