Liu, Tao (author), Ji, Wen (author), Gkiotsalitis, Konstantinos (author), Cats, O. (author)Transfer optimization in public transport (PT) networks can be achieved through coordinated timetabling and vehicle scheduling. Traditionally, the coordinated timetabling problem is solved first before proceeding to the vehicle scheduling problem. The integration of these two problems can help further reduce the total operation cost and...journal article 2023

Gkiotsalitis, K. (author), Cats, O. (author), Liu, T. (author), Bult, J. M. (author)The trips of a high-frequency urban rail line are typically planned with the aim of achieving even time headways. This results in reliable services for each urban rail line, where successive trips have the same time headway. Maintaining even time headways for each service line has significant advantages for the passengers of the line, but it...journal article 2023

Liu, Tao (author), Cats, O. (author), Gkiotsalitis, Konstantinos (author)While transferring between public transport services has a negative impact on the level-of-service, it is an inevitable feature of public transport networks. Transfer coordination can help reduce passenger transfer waiting times and improve service connectivity. In this paper, we systematically review the literature on transfer coordination...review 2021

Gkiotsalitis, Konstantinos (author), Eikenbroek, Oskar A.L. (author), Cats, O. (author)Travel time and demand disturbances lead to unreliable bus operations and missed passenger transfers. This study formulates the multi-line synchronization problem as a robust min(i)max problem that considers the fluctuations of the travel and dwell times of bus trips. Given the infeasibility of the multi-line synchronization problem in...journal article 2020
