The target of this diploma thesis is to create and compare variants dealing with a complicated traffic situation in Brno-Komín. Two dynamic responsive signal-controlled junctions situated in close proximity constitute the researched area. The situation is complicated by the presence of a streetcar crossing. Conducted traffic surveys represent the first part of the thesis. Data supplied by a junction's administrator are then added to the survey results. All acquired data serve as background information for designing possible solutions. Most of the work is connected with a capacity analysis which is done according to valid regulations. A microscopic simulation is implemented to examine impacts of selected concepts. The presented concepts are then evaluated financially. Finally, an optimal variant for implementation is suggested.
