Abstract |
High-speed trains often experience minor and major collisions during the process of stopping at towing lines and stations at the end of vehicle operations. Damage to vehicles due to high-speed train accidents cause disruptions in operational driving, which leads to physical and human damage. Therefore, there is a need for a system that can stop at a precise location when docking or stopping within a station for high-speed trains. For conventional railways, substantial costs are incurred because they use the coils called ATO (Automatic Train Operation) to control the stopping position of vehicles through an internal communication network. In this study, we verified the applicability considering distance errors due to front vehicle curvature and diffuse reflection, as well as gaps with forward trains through real-time location (distance) analysis for a precise positioning stop system using laser distance sensors. |
