The main characteristics of a transport network are the intensity of the traffic flow, speed and density of its traffic. Comfortable driver's traffic density is determined by the rule of the traffic police, which is "clearance between cars on the road should be a tenth of the speed of movement." We have built a reference curve of the density function of the flow of vehicles on its speed, which is basic when simulating a traffic flow. The article describes a model of electrical city transport networks, allowing calculating traffic flows, their speed, the density and the number of traffic lanes by means of laws of electrical engineering. We have also compared electrical concepts (current, resistance, electro-motive force, etc.) and transportation (of intensity-flow lane road, transport driving force, etc.). For the transport network there are methods of calculation of electrical circuits - a method of Kirchhoff's laws, loop currents, etc. We have confirmed the correctness of electric models and the possibility of its use for the calculation of transport networks; as well as we have presented an example of the calculation

The main causes of congestion in the city are single-level intersections regulated by traffic-lights and an insufficient number of lanes. The article provides an analysis of two problematic intersections and suggestions for their discharge. For trilateral junction of Yaltinskaya - Uralskaya with an electric model it was determined that the number of lanes needed for different areas increased to 4 - 8. However, the causes of the conflict - the intersection of two competing streams – the turn from the bridge to Yaltinskaya street to Uralskaya and oncoming traffic from Yaltinskaya to Severnaya. Traffic light regulation does not solve the problem and helps creating congestion. It is proposed to separate traffic flows on different levels with the help of the overpass on Yaltinskaya, and the stream from Yaltinskaya to Severnaya goes on the overpass, and turning stream to Uralskaya - under the overpass. Traffic flows at the intersection on Severnaya and Turgeneva with traffic light regulation device can be diluted with a circular or a turbo intersection

The volume of transportation of passengers by taxi is 6-9% of the total traffic of all kinds of public transport depends on the size of the settlement. The main purpose and the advantage of a cab is providing services for the transportation of passengers on the route, appointed by the customer, around the clock work and comfortable travel. To unload the transport system of the city, especially during peak hours, it is proposed to introduce a new type of operational-servicing passengers - a collective taxi. It is designed to transport multiple passengers traveling in the same direction, but with different destinations landing, while the fare is much lower than in a normal taxi. In organizational sense, collective taxis can be a unitary taxi company with the official standard structure and the quantity of the workers or a division of the taxi park of the city
