The traffic flow through different form of intersections

The modelling of road traffic is a very interesting area for interdisciplinary studies. Physics also offers some methodology to describe the relations between different factors influencing it. In our paper we present some studies concerning the different types of intersections, the efficiency of traffic on them and the most important factors determining it. We allow also to increase the values of flow on the road using modified Nagel-Schreckenberg model. We present fundamental diagram for this modified model and the plots showing the flows on all roads forming the intersection.
