  1. 1. Developing Markov chain models for train delay evolution in winter climate

    University essay from Umeå universitet/Institutionen för fysik

    Author : Frej Sundqvist; [2021]
    Keywords : Markov chains; Train delay;

    Abstract : The traffic on Swedish railways is increasing and punctuality is of important matter for both passenger and freight trains. The problem of modeling train delay evolution is complex since conflicts between trains can occur and since a delay can have a wide variety of causes. Swedish railways faces in addition harsh winter climate. READ MORE
