FROM PLANNING TO ASSESSMENT: THE IMPACT OF AI ON THE EDUCATIONAL PROCESS
Queirós, Ricardo; Orvalho, Luísa; Almeida, João; Kokkinogenis, Zafeiris; Mota, JorgeThis paper examines the various stages of the teaching-learning lifecycle, from initial planning to assessment and continuous refinement. Each phase - planning, creation of educational content, tutoring, assessment, and iteration - is discussed in the context of the increasing role of Artificial Intelligence (AI), emphasizing how it has been used to automate and streamline formerly manual pedagogical tasks. The...
Cooperative, Connected and Autonomous Mobility: Coordination at Intersections u...
Filipe, Francisco; Kokkinogenis, Zafeiris; D'Orey, Pedro; Rossetti, Rosaldo J. F.Road transportation is fundamental for the movement of individuals and goods, also contributing to economic development. A significant contributor to urban road congestion is poor intersection control using conventional traffic signals. In this work, we present a decentralized multi-agent system mechanism for road intersection management for connected autonomous vehicles, including the coordination of platoon f...
Assessing Communication Strategies in C-ITS using n-Person Prisoner 19s Dilemma...
Costa, António; Kokkinogenis, Zafeiris; D'Orey, Pedro; Rossetti, Rosaldo J. F.In Cooperative Intelligent Transport Systems, road users and traffic managers share information for coordinating their actions to improve traffic efficiency allowing the driver to adapt to the traffic situation. Its effectiveness, however, depends on the user’s decision-making process, which is the main source of uncertainty in any mobility system and depends on the ability of the infrastructure to communicate ...
The trade-offs between Fog Processing and Communications in latency-sensitive V...
Júnior, Francisco Mendonça; Kokkinogenis, Zafeiris; Dias, Kelvin; D'Orey, Pedro; Rossetti, Rosaldo J. F.In a vehicular fog computing paradigm, connected autonomous vehicles are envisioned as processing nodes (i.e. fog nodes) so that end-devices may offload processing tasks to them. As such, both local and distributed processing on fog nodes will depend heavily on wireless network conditions and the current traffic demand. In this work, we investigate the trade-offs on the operation of fog nodes under different ve...
Transportation Policy Evaluation Using Minority Games and Agent-Based Simulation
Baghcheband, Hajar; Kokkinogenis, Zafeiris; J. F. Rossetti, RosaldoTraffic congestion is an issue regarding the vitality of cities and the welfare of citizens. Transportation systems are using various technologies to allow users to adapt and make different decisions towards transportation modes. Modification and improvement of these systems affect the commuters' perspective and social welfare. In this study, the effect of road flow equilibrium on commuters' utilities with diff...
Route planning for electric buses: a case study in Oporto
Perrotta, Deborah; Macedo, José Luís; Rossetti, Rosaldo J.F.; Sousa, Jorge Freire de; Kokkinogenis, Zafeiris; Ribeiro, Bernardo; Afonso, João L.This paper intends to analyze the performance of an electric bus for three different routes in the city of Oporto. The objective is to study the correlation between the type of route a bus travels and the amount of energy it spends in performing it. Besides energy, the potential of the recovering part of it through regenerative braking will also be discussed. It is expected that long and demanding routes, e.g. ...
Driver attitude and its influence on the energy waste of electric buses
Perrotta, Deborah; Macedo, José Luiz; Rossetti, Rosaldo J. F.; Afonso, João L.; Kokkinogenis, Zafeiris; Ribeiro, BernardoThe objective of this paper is to analyze the influence of different driver behaviors on the energy consumption of electric buses. It shows that risk-taking attitudes on traffic are not only dangerous to the driver, to the bus users and to the surroundings, but also promotes a poorer performance of the vehicle itself, increasing its energy consumption and reducing the amount of energy that can be recovered on r...
