Measurements to estimate truck trip generation of particular facilities, such as warehouses, factories and logistics centres are rarely conducted in Poland. Those measurements are quite easy to conduct by counting vehicles entering and leaving a particular facility. Results of these studies might be used as the first step in a 4–stage model. Obtaining trip generation rates per 1 employee or 1000 sq m of company area would be useful for aggregation of trip generation from single generators to a given traffic zone. Moreover, the results would give information about daily variability in time (e.g. the peak hour). This paper presents research conducted in Krakow. The obtained trip generation rates are provided and compared with trip generation rates from other studies. Additionally, advantages and disadvantages of single generators measurement are discussed.
