Abstract:
In the theory of traffic flows the main characteristics are: intensity, speed, and density. They make it possible to use hydrodynamic models. In connection with the development of modern highways and road networks, traffic flows behavior is becoming more and more complex and diverse. In particular, the B.Kerner studies have shown that the laminar solution of hydrodynamic models is poorly correlated with experimental data. Our research team is developing tools for intelligent monitoring of traffic flows on fragments of the road network with different geometries. The paper presents a project of a client-server system, which allows obtaining, in real-time, information regarding the basic characteristics of traffic flows at the junction of any configuration using mobile devices. The automation of obtaining characteristics is based on the application of image recognition algorithms (virtual detection method).

P. Buslaev since the end of the last century is engaged in the development of the theory of transport flows, optimal control taking into account traffic jams and load modes of engines in different road conditions (Lukanin et al, 1998; Lukanin et al, Part I, 2003; Lukanin et al, Part II, 2003).
This paper presents a project of a client-server system, which allows obtaining, in real- time, information regarding the basic characteristics of traffic flows at the junction of any configuration using mobile devices.

New System The task of the application (Figure 5) is to synchronize the collection of data on the intensity of traffic flow at the intersection with several smartphones, located at given points as in Figure 6.
Thus, by calculating the number of vehicles passing through each lane in the given period we can obtain data on the intensity of traffic flow.
Results of the experiment )VIew the image of this page) Conclusion In this paper we used a client-server application to investigate the intensity of traffic flows at an intersection.
