Using traffic control systems you can solve a lot of traffic problems, such as traffic incidents, fuel consumption, delays, traffic jams, emission of pollutants, parking and others. Developing traffic control systems require less cost than other parts of the transport infrastructure improvements. If you want to implement traffic control system to the streets of cities you must to estimate all traffic factors. In order to implement all traffic factors you need to create traffic flows imitation model. The developed imitational model of the traffic flows permits the modeling of various traffic flows at the intersections. The main task of this imitation model is traffic jam detection. Imitation model was tested with real and forecasted data. The developed imitational model of the intersection can be applied to any intersection of the city.
