Title: Dynamic Location Planning For Student Urban Carpool Hubs Scientific fields: Operational research, optimization model, Location-allocation problems Key words: Student mobility, carpool hub location, optimization, sustainability Supervision: Houda TLAHIG (EC), Mohamed Amin BENATIA (EC) Abstract The aim of this internship is to develop an optimization model to decide dynamically the location of Urban Carpool Hubs (UCH) serving university campuses. The model should guarantee the effective allocation of students to these UCHs taking into account different options such as face-to-face or distance courses. Considering the campus timetable constraints, the main objective is to identify the most sustainable location minimizing the travel cost and the environmental impact. Given the dynamic nature of urban environments, the location model should incorporate variables such as transportation disruptions and be flexible enough to evolve in response to the changing needs of students. Internship project - Scientific Context This internship is part of CESI's MobE program. This program aims to understand and optimize student mobility in favor of energy savings, and to engage higher education establishments in a transformation of student mobility via an integrated approach of analysis, methodological input and wide dissemination to students and higher education establishments. Our aim is to reduce the carbon footprint of student travel, while proposing efficient alternatives based on soft mobility (walking, cycling, scootering, etc.) and any other means of mobility, whether collective or individual, that contribute to a reduction in CO2 emissions (such as public transport or car-sharing). Subject Description The growing urban population in urbanized areas is causing a surge in congestion and environmental pollution. In response to this challenge, the European Commission promotes Sustainable Urban Mobility Plans (SUMPs) as a comprehensive planning approach that addresses all transportation modes within cities and their surrounding regions [3]. This concept has also been applied to smaller areas, such as university campuses, recognizing universities as ecosystems where people cover significant distances to access various locations throughout the day. Internationally, diverse transportation policies and plans have been implemented to improve overall mobility quality within university campuses. Notable examples include the integration of university planning with city transportation planning, as observed in Barcelona's implementation of superblocks. The University of Bristol has interconnected its facilities across the city through a comprehensive travel plan for both staff and students. Similarly, the Polytechnic University of Turin has devised a strategy for regulating cycle lanes and parking based on the transportation behaviors and mobility needs of its university community [1]. In the [2], the authors presented a detailed study on the development of the Sapienza Sustainable University Mobility Plan (SUMP to enhance the sustainability of transportation methods for both students and staff. In this context of urban mobility, carpooling (based on a shared use of private cars) is considered as an alternative transport system, which may contribute to enhance the sustainability of student mobility. Some studies dealt with this problem in the literature. In [6], authors studied a car-pooling service for Università Statale and Politecnico di Milano universities aiming to maximize the number of served users, minimize the total route length, and maximize the satisfied user preferences. In [7], a carpooling system is studied as an alternative mean of transportation to solve a parking problem encountered by the Binghamton University. In this internship, we aim to develop an optimization model to minimize the cost and environmental impacts of the student move from their homes to their university campuses through carpooling. Considering constraints related to the timetables scheduling, it is about studying urban carpool hub locations and student allocation to these shared hubs. One of the major goals is to contribute to more sustainable mobility by reducing the predominance of private cars and helping to change mobility behaviors toward more sustainable practices. Selecting an optimal location for an urban carpool hub should consider aspects like the outstanding connectivity to diverse transportations modes, the proximity to educational institutions and the respect of the timetables scheduling constraints. Given the dynamic nature of urban environments, dynamic planning location of these hubs is crucial to ensure efficiency and accessibility [5]. The term "dynamic" emphasizes the need for responsiveness to changing patterns in student population distribution, in commuting availability, and modifications in urban infrastructure over time. Critical factors, such as the distribution of student populations, proximity to educat
