Intersection is a basic element in the technology of urban traffic regulation. It is such object where city roads intersect and which is the main cause and source of congestion. Therefore, first of all, it is necessary to implement the intellectual regulation of vehicles movement through a separate intersection. Such regulation is carried out with a help of a computer program that takes into account the vehicle road situation at the intersection and the corresponding correction of the traffic lights signal phases. At a second stage it is necessary to plan an optimal route for each vehicle using, for example, A*-algorithm and the spectrum of data received from an infrastructure of the urban network. As a result of an application of these two phases of urban traffic regulation, an optimal movement regime of all city mobile transport is achieved. This work is practical and aimed at solving a specific problem – traffic problem in a big city.
