A dynamic estimation of passenger OD matrices based on space-state models
(2013)
Text en actes de congrés
Accés obertDynamic 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 DUE based bilevel optimization approach for the estimation of time sliced OD matrices
(2014)
Text en actes de congrés
Accés obertTraffic management applications are supported by dynamic models fed with realistic real-time demand matrices in order to find efficient solutions in the short-term horizon. OD matrices have to be estimated from historic ... -
Microscopic simulation with AIMSUN for the assessment of incident management strategies
(2002)
Text en actes de congrés
Accés obertPRIME (Prediction of Congestion and Incidents in Real Time, for Intelligent Incident Management and Emergency Traffic Management) was a project of the 5ht Framework Program of the European Union which objectives were to ... -
Incident management combined with traffic management
(1998)
Text en actes de congrés
Accés obert -
A practical proposal for the use of origin destination matrices in the analysis, modeling and simulation framework for traffic management
(2013)
Text en actes de congrés
Accés obertDealing with traffic demand trip matrices to feed models to support decisions in traffic management is still a problem that deserves research efforts, aimed to find practical solutions applicable in the short term horizon, ... -
Formal and operational validation of a bus stop public transport network micro simulation
(2014)
Text en actes de congrés
Accés obertWe present a detailed simulation model with the purpose of analyzing the congestion and interaction between bus lines and passengers at stops. Our main goal is to perform a complete validation of a simulation model formalized ... -
Kalman-Filtering formulation details for Dynamic OD passenger matrix estimation
(2014)
Text en actes de congrés
Accés restringit per política de l'editorialIn this paper, we describe how to estimate time-sliced origin-destination (OD) matrices for passengers in a public transport network based on counts of ICT (Intelligent Communication Technology) devices carried by ... -
A simplified model for scheduling services on auxiliary bus lines
(2014)
Text en actes de congrés
Accés restringit per política de l'editorialIn this paper, a mathematical programming based model is described to assist with the schedule of services for a set of auxiliary bus lines that operate alleviating a disruption of the regular transportation system during ... -
Robustness and computational efficiency of a Kalman Filter estimator of time-dependent origin-destination matrices: exploiting ICT traffic measurements from information and communications technologiess
(2013)
Text en actes de congrés
Accés obertOrigin–destination (O-D) trip matrices that describe the patterns of traffic behavior across a network are the primary data input used in principal traffic models and, therefore, a critical requirement in all advanced ... -
A flow formulation for the optimum communication spanning tree
(Universidad de La Laguna, 2013)
Text en actes de congrés
Accés obertIn this paper we address the Optimum Communication Spanning Tree Problem. We present a formulation that uses three index variables and we propose several families of inequalities, which can be used to reinforce the ... -
Allocating refuse bins for selective waste collection, a case study
(2007)
Text en actes de congrés
Accés obertOne of the problems found in Municipal Waste Management is the allocation of refuse bins to different collection areas where waste (glass, paper, plastic, organic material) is left by the citizens. The relationship between ...
