Description	The domain of pedestrian dynamics studies suffers from the lack of experimental data, which are very important both for primary research and also for calibration and verification of the models. To realize a reliable experiment, the %22normal%22 conditions must be kept, otherwise the participants behave differently than in the ordinary situations. Simultaneously, the design must be simple enough, the motivation of participants and other parameters influencing the decision process must be easy to assess. To track a motion of one person, it is necessary to monitor both, velocity and directions, therefore video records are frequently used. The data from cameras are difficult to process - the snapshots are garbled by angle of view and other phenomena. This contribution deals with all tasks described above, it illustrates the process of planning, monitoring and evaluating the experiments. The concept of microscopic and macroscopic approach is presented and the basic quantities describing pedestrian movement - pedestrian's density and flow - are defined. With respect to the goals of given experiment, different methods of extraction these quantities from records are used. At the end, the analysis of velocity - density dependence, occupancy and the time headways of leaving pedestrians is provided.
