Modelling as a Means of Improving the Organization of Movement of the City Traffic

Abstract: The paper show the results of an application of system Vissim to the microscopic simulation of traffic flow for a fragment of a real urban road network. First, the problem of traffic flow modelling and simulation was described, and the selected system is introduced. A crossroad on one of the main boulevards in the city of Ruse was chosen to be explored through a simulation model. The model examine the impact of traffic light cycle on the queue, the transport delay and the number of vehicles that have passed.
