Garcia Ródenas, Ricardo; López García, Maria Luz; Cadarso Morga, Luis; Codina Sancho, Esteve (Elsevier, 2022-03-11)
Article
Accés obertUnexpected events may perturb operations and generate conflicts that must be addressed promptly to limit delay propagation and other negative impacts on the network. The real-time railway traffic management problem deals ... -
A model for the simultaneous selection of bus lines and frequency setting problems in the expansion of public transit systems
Maureira Alegría, Grace Kelly; Codina Sancho, Esteve (Elsevier, 2020-03-02)
Article
Accés obertWhen expanding an existing public transport system a common practice consists of defining a set of candidate new lines andfrom them, choose those that will revert into a greater increase of the system’s performance while ... -
A model that assesses proposals for infrastructure improvement and capacity expansion on a mixed railway network

Article
Accés obertThis paper presents a mathematical programming-based model for evaluating the impact on a mixed railway network from proposals for infrastructure improvement and capacity expansion that are oriented mainly toward increasing ... -
A multi-objective programming model for timetables on corridors integrating macroscopic and microscopic approaches
Marín Gracia, Ángel; Codina Sancho, Esteve (Elsevier, 2020)
Article
Accés obertThis paper proposes an integrated framework for timetable design that meets the needs of service planners, who usually adopt a purely macroscopic point of view toward the demand requirements and conflicts that these ... -
