Gkiotsalitis, K. (author), Wu, Z. (author), Cats, O. (author)Urban public transport operations in peak periods are characterized by highly uneven demand distributions and scarcity of resources. In this work, we propose a rule-based method for systematically generating and integrating alternative lining options, such as short-turning and interlining lines, into the frequency and resource allocation problem...journal article 2019

Ghaemi, N. (author), Cats, O. (author), Goverde, R.M.P. (author)In case of railway disruptions, traffic controllers are responsible for dealing with disrupted traffic and reduce the negative impact for the rest of the network. In case of a complete blockage when no train can use an entire track, a common practice is to short-turn trains. Trains approaching the blockage cannot proceed according to their...journal article 2018

Ghaemi, N. (author), Zilko, A.A. (author), Yan, F. (author), Cats, O. (author), Kurowicka, D. (author), Goverde, R.M.P. (author)Disruptions such as rolling stock breakdown, signal failures, and accidents are recurrent events during daily railway operation. Such events disrupt the deployment of resources and cause delay to passengers. Obtaining a reliable disruption length estimation can potentially reduce the negative impact caused by the disruption. Different factors...journal article 2018

Ghaemi, N. (author), Cats, O. (author), Goverde, R.M.P. (author)Currently railway traffic controllers use predefined solutions (contingency plans) to deal with a disruption. These plans are manually designed by expert traffic controllers and are specific to a certain location and timetable. With a slight change in the timetable or infrastructure, these plans might not be feasible and have to be updated....journal article 2017
