Abstrakt EN: The main contribution of the paper is a description of relevant data pro-cessing and visualization techniques. These techniques were applied and tested in the frame of the European project OpenTransportNet (CIP-ICT-PSP-PB 620533). There are four pilot regions where these techniques are being applied: the city of Antwerp, Birmingham, Issy-Les-Moulineaux? and the Liberec Region. The paper firstly analyses contemporary progressive methods for dy-namic phenomena visualization and methods which are suitable for traffic flow management in the area of interest. The next section of the paper explains the nature of traffic volume as a variable, the way how it can be measured on key network segments and then calculated for the whole network. The following process of estimation of the traffic volume time variations including short and medium-term prediction is also out-lined. The paper describes the change of geographic data structure on the example of traffic data. This change is necessary for visualization of spatio-temporal data in contemporary clients. Finally, the selected visu-alization method is implemented in an online client.
