Places of crossing the roadway by pedestrians, regulated by traffic lights, provided largely safe passage. In these cases attached times of individual signals have to guarantee minimum delay of both streams. The paper presents a calculation algorithm for pedestrian green time according to the intensity of traffic flows and pedestrian flows in certain road conditions.

Traffic lights regulation reduces conflict points in intersection of traffic flows trajectory and provides their safety crossing. The main in installation of traffic lights is determination of a cycle length which guarantee minimum waiting time of traffic flows at the junction. The paper presents a calculation algorithm for the cycle length of a traffic light junction according to traffic flows intensity, saturation flows and day periods which are have deferent intensity.
