Conflict Resolution and Train Speed Coordination Solving Real-Time Timetable Perturbations

Abstract

In this paper researchers present a method of rail traffic control and train scheduling to provide conflict resolution given a real-time timetable perturbation. Upon the determination of a conflict resolution for vehicle speed and coordination, the relevant data points such as the goal location, time, and speed could be relayed to conductors who could then adjust the speed accordingly. The model presented here also provides a determination of safe distance headway in addition to speed coordination issues with consecutive trains on the same track. Researchers applied their method computationally to existing rail networks between Leiden and Amsterdam in the Netherlands. They then considered 48 different test cases of potential perturbations in that network to test the efficacy of their system, particularly in the event of a highly disordered dispatching system. The researchers demonstrate the effectiveness of their variable-speed model as against a fixed-speed scheduling system.
