Purpose: As life expectancy increases around the world, it also grows the number of people with reduced mobility (older adults and disabled individuals), leading to a need to rethink transport planning in urban areas to include these individuals. To accomplish this, city planners must understand the key features that most influence the travel behav...

Railways are generally much more efficient than road transport in terms of energy consumption for both freight and passengers. Despite this, it is still necessary to reduce their energy consumption in order to improve their competitiveness and contribute to a global sustainability. This thesis presents the training of an artificial neural network...

Project
ANTOINE is a data analytics platform & decision support tool that will empower the operational & tactical decisions of intermodal freight activities. Thanks to a Machine Learning approach, combined with stochastic optimisation & simulation, the tool will serve as a cockpit by forecasting operational issues, and identifying robust solutions to handle disruptions & stochasticity stemming from train delays, wagon breakdowns, etc. In the long run, by integrating rail processes with maintenance operations and costs, ANTOINE allows the reduction of overall system costs. The tool will be implemented in real life within the CFL freight activities, and especially on their intermodal terminal operations. Its performance will be evaluated and compared to the currently used heuristics. ANTOINE will contribute to the process of digitalization of CFL intermodal and to the country’s Smart Logistics specialization strategy priority.

In recent decades, transportation planning researchers have used diverse types of machine learning (ML) algorithms to research a wide range of topics. In this project we want to study different ML approaches for modeling travel mode choice rather than the commonly used Multinomial Logit Model (MNL) which is the most commonly-used discrete choice model used for this purpose.
