Train control involves the reception of environmental (track, signal, obstacle) signals, as well as information from indicators on the control panel, which are constantly analyzed and processed to make the right decision. The smooth operation of the train also depends on external visibility. The paper analyzes the visibility from the driver's cab under different driving conditions and ways to improve the conditions of external visibility. The limited visibility encountered during the dark hours of the day, in difficult weather conditions or on road curves, is one of the most common causes of collisions with obstacles on railway tracks. By visually observing the ever-changing environment on the road, it is important to identify threats in a timely manner and make timely decisions. The paper investigates the stopping distance of train, visibility on a curve and in conditions of limited visibility, sun glare factor while operating a train. In view of these stimuli, there is a need for additional visibility measures. Quick decision-making is needed to avoid potential collisions (such as unexpected obstacles on the road) when driving at night or in bad weather. The train stopping distance is often longer than the visibility in the direction of travel, so additional equipment to detect obstacles in time is necessary. One solution to the problem is to propose the use of thermal infrared cameras, which transmit a direct view to the driver’s cab, helping to detect an obstacle from a greater distance. |
