Simulation of a Safe Train Traffic Management System at the Stations

These days, automation and remote control technologies provide the foundation for the organization of train movement across several categories. At railroad sections and stations, dispatcher centralization systems are utilized to guarantee the security of train movement. However, in the railroad portions where high-speed train movements are organized, time limitations based on the human factor are being implemented. Consequently, this results in longer wait times for technological processes at stations and longer train intervals on some railway segments. Developing an automated route preparation procedure at stations in dispatching centralization systems will allow for the resolution of current issues. A dispatching centralized system model for route establishment has been created in this scientific study. Using a two-layer neural network, a mathematical model of route setting in the dispatcher centralization system was determined. Neural networks are employed in rail dispatch rooms for intelligent route comparison and in dispatcher centralized systems for tracking train routes at stations.

“…Every station has many pairs of control points installed on the approach section. It is found that the intervals between these locations correspond to the electrical centering system's mode entry times [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. When the rolling stock approaches the station, the first of the two control points notifies the interlocking system.…”

“…2, a -For high-speed trains, the following expressions (4), ( 5), (6), and ( 7) are used to calculate the distance between the first and second control points in the figure as well as the rolling stock's time of movement. High-speed train braking times are expressed as follows: (4) for high-speed train braking times between 0 and 108 km/h, (5) for high-speed train braking times between 108 and 350 km/h, and ( 6) and ( 7) when braking is an expression of the path [15][16][17][18][19][20][21][22][23][24].…”

Functions of the interlocking system on mixed traffic lines

These days, automated rail traffic control systems help to lessen the need for human intervention in train traffic management. On the other hand, the various algorithms used by interlocking systems to coordinate the movement of trains belonging to distinct categories result in longer wait times for technological procedures at the station. The possibility of timely routes for trains of multiple categories occurs by employing the method of automatic route preparation by interlocking systems in the organization of the movement of trains of different categories. In interlocking systems, automatic route preparation can be achieved by continuously monitoring train characteristics, train traffic graphs of various train classes, and the condition of equipment involved in the function’s development. Nonetheless, it is predicated on the creation of many models to arrange the specifications of various train classes and train movements inside a single schedule type. In order to prepare the routes ahead of time for the station tracks based on the algorithms for the operation of interlocking systems for various kinds of trains, the paper analyzes the reliance of the traffic composition characteristics.

“…If the railway sections approaching the trains are equipped with a semi-autoblocking system, in this case, the system that transmits the message about the approaching trains to the creatures, the noise generator is activated at the contact of the track relay of the rail chain or track sensors at the same distance from the point where the creatures gather in the even and odd directions [15][16][17][18][19][20][21][22][23][24].…”

Incidents of train collisions with creatures on railway tracks are one of the major problems for railway transport today. The scientific article presents the results of the analysis of cases of trains hitting people and creatures on railway sections. Taking this into account, the aim of the scientific work is to develop a system of automated warning messages to creatures on railway tracks of approaching trains. In the creation of the system, the notification of the approaching trains to the creatures was selected based on the frequency of hearing of the creatures that gather a lot on the railway sections. In the article, the working algorithm of the system for notifying creatures of the noise generator of the approach of trains, as well as the types of auto-blocking systems on railway sections, to start the noise generator that transmits the message of the approach of trains, if the railway tracks are equipped with the auto-blocking system, the rail chains or the railway tracks are equipped with a semi auto-blocking system connecting the road sensors that notify when the train is approaching to the contacts of the road relays, and recommendations on the selection of frequencies for the noise generator of the train approach warning system based on the hearing frequency of the creatures that gather in large numbers around the railway sections.
