In July 2008, system of partial payments on motorways was aborted and for most of the traffic replaced by a vignette system. Vignettes are bought in advance and are valid for a longer period of time. The switch of system caused major changes on traffic – traffic increased on motorways and decreased on some lower order state roads (for which payment is not demanded). The biggest change is seen in toll station areas. Increased traffic on motorways caused shorter distances among vehicles and more interplays, which demands higher concentration of a driver. On the other hand, increased traffic on motorways loosened traffic on lower order state roads, especially on those which were used before as a bypass of toll station areas (with intention of avoiding paying toll). The vignette system does not require stopping at toll station for vehicles lighter than 3,5 tone. It means higher flow and less traffic jams in toll station areas. But at the same time, it makes integrating trucks back to lane even more effortful. The increase of traffic in toll station areas and changes related to it are demonstrated in this thesis. In order of making those demonstrations, I interpreted information about: car accidents (number, type, cause, classification), traffic flow reorganisation in toll station areas, changes of traffic structure. Information about traffic is collected from automatic traffic counters and car accidents are summarized after information collected by Police.
