A mesoscopic traffic simulation based dynamic traffic assignment

Linares Herreros, Mª Paz (Date of defense: 2014-04-24)

In terms of sustainability, traffic is currently a significant challenge for urban areas, where the pollution, congestion and accidents are negative externalities which have strongly impacted the health and economy of ...

Combination of vehicle routing models and dynamic traffic simulation for city logistics applications

Grzybwska, Hanna (Date of defense: 2012-06-08)

The urban network is a highly dynamic system. Thus, a modern and efficient fleet management in urban areas should account for dynamics of traffic conditions, variability in travel times, changes in demand and fleet ...

Conjoint design of railway lines and frequency setting under semi-congested scenarios

López Ramos, Francisco (Date of defense: 2014-02-24)

This thesis develops mathematical programming models which integrate network design (ND) and line frequency setting (LFS) phases. These appear in transport planning studies that extend an existing urban public transportation ...

Dynamic OD matrix estimation exploiting ICT traffic measurements

Ros Roca, Xavier (Date of defense: 2021-10-01)

During the last decades, urban mobility has become the main concern for city councils and transportation operators. The main problem is the traffic congestion that easily appears in urban networks, producing negative ...

Mathematical programming models to design and analyse efficient and robust raiway freight transport networks

Rosell Camps, Francisca (Date of defense: 2022-11-10)

(English) Searching to achieve an ambitious reduction in greenhouse gas emissions, the European Union has set as a goal a modal shift in freight transport of 30\% by rail or waterborne for the near future. The increasing ...

Models and Algorithms for Location-Routing and Related Problems

Albareda Sambola, Maria (Date of defense: 2003-06-02)

The most common decisions to be taken in the design of logistic systems are related to the location of facilities and the management of vehicle fleets.<br><br/>In this thesis, we study three of the optimization problems ...
