Diploma thesis deals with microscopic traffic model of the streets Veveří and Kounicova including adjacent road network. This model was created in software Aimsun based on maps, the results of the directional survey, traffic intensity at junctions and signal plans. Elaborated model of the current state location of interest was calibrated according to the traffic intensities on the entrance and exit roads. They have also been designed and created three possible variants of the solution streets Veveří and Kounicova. All variants were finally compared and evaluated.
