The main goal of this dissertation is to answer one of the critical questions about dynamic ride-sharing services: Can dynamic ride-sharing reduce congestion? In this thesis, we propose a simulation-based optimization framework for dynamic ridesharing. Then using this framework, we assess the dynamic ride-sharing impact on two different network sca...
Les temps de stationnement en gare en Île-de-France peuvent avoir un impact significatif sur la régularité des trains transilien. L'optimisation des durées de stationnement est essentielle pour une exploitation efficace, en n'étant ni trop courtes, ni trop longues. Le déploiement d'un système de comptage automatique des voyageurs embarqué permet de...
The aim of this study is to solve the large?scale dynamic traffic assignment (DTA) model using a simulation?based framework, which is computationally a challenging problem. Many studies have been performed on developing an efficient algorithm to solve DTA. Most of the existing algorithms are based on path?swapping descent direction methods. From th...

This work attempts to validate the dynamic outputs of bi-modal MFD based models, also referred to as 3D-MFD models, using empirical data. A previous study (Loder et al., 2017) gathered cars and public transport vehicles data in two different regions of Zurich city and showed that a well-defined 3D-MFD exists by proposing a functional form relating ...
Taxis are an important transportation mode in many cities due to their convenience and accessibility. In the taxi-dispatching problem, sometimes it is more beneficial for the supplier if taxis cruise in the network after serving the first request to pick up the next passenger, while sometimes it is better that they wait in stations for new trip req...

In railway systems, during congested traffic situations, the infrastructure capacity is completely exploited for trains circulation. When traffic is perturbed, some trains must be stopped or slowed down for ensuring safety, and delays occur. The real-time Railway Traffic Management Problem (rtRTMP) is the problem of modifying trains route and sched...
