Solution Overview

Problem

Current methods for tracing the propagation of delays in railway systems are inefficient and inconsistent due to their reliance on manual assessment, lacking automated processes to determine and analyze the relationships between train stops and their causes, especially in single-track railways.

Innovation Solution

A computer system and method that utilizes sensors to collect data on train stops, classifies them as primary or secondary, and uses algorithms to automatically determine associations between these stops, displaying and updating these associations through a graphical user interface with user input for enhanced accuracy.

AI summary

System and methods for determining a propagation of delays. In some embodiments, a computer system includes: a processor; a non-transitory computer readable medium that stores instructions that when executed by the processor causes the processor to execute operations. The operations may include receiving first information related to a first stop by a first train on a first track and receiving second information related to a second stop by a second train on the first track. The operations may further include determining an association between the duration of the second stop of the second train and the reason for the first stop of the first train and displaying an indication of the association on a graphical user interface. Lastly, the operations may include determining an updated association between the first stop and second stop based on a user input into the graphical user interface.
