■ infrastructure condition monitoring and rolling stock diagnostics unit;
■ backbone and technological communication networks and data transmission systems;
■ situational management center with analytical and control systems.
The decision-making scheme in this system is based on an object-oriented model (the operational state of the direction), the construction of an up-to-date train schedule based on the analysis of the regulatory schedule and planned restrictions, taking into account the work carried out by infrastructure facilities of JSC «Russian Railways», monitoring the actual execution of the schedule at the moment, taking into account satellite positioning data. Train driving with the help of the system under consideration is based on a set of hardware and software and functional applications of intelligent car driving, using data on the actual train position, data from the automatic route preparation system, forecast graphs, information from the GID «URAL» system, data on speed limits on sections. The considered components of the intelligent dispatching control system were successfully tested in the organization of high-speed train traffic «Sapsan».
The developed hardware and software tools and technical solutions in the field of creating intelligent railway transport make it possible to organize centralized automated control of train traffic on the railways of JSC «Russian Railways» at a qualitatively new level with the provision of functional, informational, environmental and fire safety. The scientific and technical potential accumulated in this field will contribute to the creation of a new generation of locomotive safety devices, the practical use of GLONASS/SRB satellite navigation technologies and a digital radio channel for complex multi-level traffic safety systems. The development of ITS will make it possible in the near future to ensure the quality of transport services and the safety of transportation on the railways of Russia and in general in the «1520 railway track» at the level of the best world standards.
2.2 Current issues of ITS development
Intelligent transport systems (ITS) are the result of the system integration of modern navigation, information and communication technologies, automation, transport infrastructure, user facilities, focused on ensuring the safety and efficiency of the transport process, logistics, and improving comfort for drivers and passengers.
