Title: The influence of buffer time distributions in delay propagation modelling of railway networks
Buffer times are an important element in railway schedule design preventing the propagation of delays. Current analytical delay prediction models are mostly based on the assumption of exponentially distributed buffer times. It has been shown that real-world data forb buffer times deviates from this behaviour, such that more general buffer time distributions are required. In the talk, the impact of different buffer time distributions on the height of knock-on delays is analysed using a Monte-Carlo simulation approach. The goal is to clarify how model refinements can be expected to influence capacity indicators or the level of service.
