Research report
Open AccessThe class of simplicial decomposition methods has shown to constitute efficient tools for the solution of the variational inequality formulation of the general traffic assignment problem. The paper presents a particular ... -
A dynamic estimation of passenger OD matrices based on space-state models
Montero Mercadé, Lídia; Codina Sancho, Esteve (2013)
Conference report
Open AccessDynamic OD passenger matrices must be taken into account when designing robust public transport systems. The adjustment of these matrices is examined using passenger counts provided by a space-state model formulation in a ... -
A heuristic method for a congested capacitated transit assignment model with strategies
Codina Sancho, Esteve; Rosell Camps, Francisca (2017-12)
Article
Open AccessThis paper addresses the problem of solving the congested transit assignment problem with strict capacities. The model under consideration is the extension made by Cominetti and Correa (2001), for which the only solution ... -

Montero Mercadé, Lídia; Codina Sancho, Esteve; Barceló Bugeda, Jaime; Barceló, P (1998)
Conference report
Open AccessTraffic assignment models based on the user equilibrium approach are one of the most widely used tools in transportation planning analysis. Based on Wardrop’s, principle as a behavioral principle modeling the route choice ... -
A mixed-integer linear program for real-time train platforming management
Garcia Ródenas, Ricardo; López García, Maria Luz; Cadarso Morga, Luis; Codina Sancho, Esteve (Elsevier, 2022-03-11)
Article
Open AccessUnexpected 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
Open AccessWhen 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
Rosell Camps, Francisca; Codina Sancho, Esteve (Elsevier, 2020)
Article
Open AccessThis 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
Open AccessThis 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 ... -
