International audienceAt present, practically all of the larger cities are battling with a range of problems with transport, which starts from an extensive number of motor cars. This number, in proportion to population, in the Czech Republic since 1990 has been rising by a steep curve and in Prague it is situated at the top of European metropolises at the moment. It ́s true that means passengers efflux in the urban mass transportation (UT) which contributes to degradation of it ́s importance and thus attractivity as well. A separate problem is the urban pattern of the cities that has been composed for many centuries and isn ́t prepared for the acute impact of automobile conveyance. It was the UT, on the contrary, which co-formed the colonisation and with its aesthetical elements and pedestrians coexistence kept the classical urban qualities. To continue as one of the essential functions of the city at present as well, the UT has to become competitive with motor cars. As one of the keys for the solution, the priority for the UT prior to the cars comes out. The increase of travelling speed as a primary effect brings a lot of further advantages, in terms of transportation engineering not only. Modern methods of the priority for the UT utilize many elements and arrangements constructive, operational, legislative. In the conditions of Czech cities the operational priority on the stoplight-controlled crosswords, which uses the branch of transport telematics as well, seems to be the most effective at the moment. The factor of the priority for UT is influenced mostly by communal politics, which we can see on the number of positive instances abroad
