2. Analysis of the existing studies on traffic organization and management 
Leading scientists in the field of traffic arrangement and management are Drew, Klinkovstein, Larin, Gasnikov, 
Domke, Gasanov, Siliyanov, Stolyarov, Lobanov, Kremenets and foreign authors Heit, Enose, Přibyl, Webster, 
Kerner, and others. The papers of these authors considered the issues of traffic arrangement, traffic flows 
management (Bester and Meyers, 2007; Přibyl and Svitek, 2003; Lin et al., 2014). Some of the proposed measures 
for increasing the traffic flows management efficiency due to the varied indicators shall be adjusted and improved 
(Isaeva, 2017). The previous studies do not take into account the variety of factors affecting the delays in the road 
network and efficiency of vehicle use. Siliyanov developed the models considering the impact of roads and road 
conditions on the traffic flow parameters. Stolyarov and Shchegoleva (Novikov et al., 2014) created the traffic flow 
model allowing sequential determination, depending on road conditions, traffic composition and permissible risk of 
accidents, speed and density of traffic flow, as well as rate and density of traffic congestion resorption. However, the 
impact of road parameters on the congestion occurrence was not studied. 
The factors affecting the traffic flow are shown in (Fig. 1). The main groups of factors depend on a driver, 
vehicle, roadway, its surroundings, weather conditions of traffic.

Concerning the traffic assessment levels, it is obvious that they are interrelated. The strategic traffic management 
level is a political and scientific aspect from the point of view of preserving and increasing population mobility, 
responding to trends and forecasts taking into account the environmental load reduction by means of introduction of 
new solutions. Traffic assessment at this level primarily represents the shortcomings of the currently used type

/method of transportation compared to the new proposed options. The planned level is aimed at finalizing, 
developing and implementing the existing or required resources to implement the strategic goals. The strategic goals 
are mainly implemented by means of planning (building) solutions. The traffic assessment in this case serves as a 
tool for checking the existing roads and assessing new solutions. At the operational traffic management level the 
ideas of the planned traffic management level are implemented directly in the real traffic process, taking into 
account the planned transport and road network (Afanasyev and Panfilov, 2017). Here, in the foreground there is the 
traffic assessment that is an assessment for movement of a real traffic flow along the proposed transport 
infrastructure. The information cycle between the strategic, planned and operational management level is presented 
in (Fig. 2). The system complexity is enhanced by the mutual influence of objects: transport infrastructure, vehicles, 
traffic. 
The listed traffic management levels necessarily include the stage of assessing the existing traffic level and its 
subsequent prediction (Kerimov et al., 2017). In this regard, there is a need to develop a procedure for assessing the 
traffic level reflecting the dependence of traffic on the relevant affecting factors (Batishcheva and Ganichev, 2017).
