A method for constructing train delay propagation process by mining train record data

Paper first proposes a method for identifying delay propagation process between two trains and then puts forward an approach for reconstructing train delay propagation chains(trees).A case study is conducted to test the proposed methods.The case study concerns one of the busiest railway lines in the Netherlands,'Leiden-The Hague-Rotterdam-Dordrecht-Dordrecht South' with operations data recorded in February 2009.Topics considered are conflict/delay propagation chains and structural route conflicts.Results show that the proposed methods are effective and easy to implement,which yields great potential for practical use in railway industries.
