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...
Serious games for the human behaviour analysis in emergency evacuation scenarios
Almeida, João Emílio; Rossetti, Rosaldo J. F.; Jacob, João Tiago Pinheiro Neto; Faria, Brígida Mónica; Leça Coelho, AntónioThis paper describes an experiment designed to elicit human behaviour when facing the urgent need of exiting an unknown building. This work is part of a larger effort to devise the methodological approach underlying the implementation of simulation of pedestrians and elicitation of their emergent dynamics, an experimental framework coined SPEED. To validate our experimental setup, a group of 16 experts on fire ...
Social simulation of rescue teams’ dynamic planning
Ulisses, João; Rossetti, Rosaldo J. F.; Almeida, João E.; Faria, Brígida MónicaThis paper focuses on an approach to dynamic planning, for an emergency ambient such as team rescue in indoors fire. First a graph is generated as the simulation runs, creating an effect similar to means-end analysis as each fire trying to reach the firefighter. This graph is updated in real time, improving the solution performance and reacting to new fires. The firefighter creates a plan based on this graph, u...
Elderly and fire safety: using serious games to elicit human behaviour in evacu...
Almeida, João E.; Rossetti, Rosaldo J. F.; Faria, Brígida Mónica; Coelho, António Leça; Faria, Brígida MónicaThe problem of leaving a building while facing some emergency has gained much attention from the scientific community. Evacuation simulators can help emergency planners to assess the safety of buildings. However, such simulators still lack behavioural knowledge to increase their accuracy. The elderly have specific behaviour idiosyncrasies. This paper presents a set of experiments designed to elicit human behavi...
Using serious games to train children and elicit fire safety behaviour
Almeida, João E.; Rossetti, Rosaldo J. F.; Faria, Brígida Mónica; Coelho, António LeçaSerious Games are being increasingly used as a tool for various applications, contrary to the traditional entertainment purpose. One of their application domains is fire safety. Possible injuries from fires are a dangerous safety concern for children, for instance. Another important issue is the elicitation of behavioural knowledge to design and feed simulation models. The lack of human behaviour data is often ...
Towards a methodology for human behaviour elicitation: preliminary results
Almeida, João Emílio; Rossetti, Rosaldo J. F.; Faria, Brigida Monica; Jacob, João Tiago; Coelho, António LeçaHuman behaviour knowledge is an important requirement for implementing realistic evacuation models. Although much work has been done in this field of research there are no universally accepted quantitative methods. In this paper we present a novel methodology for human behaviour elicitation that was coined SPEED (Simulation of Pedestrian and Elicitation of their Emergent Dynamics). An experimental setup to test...
Serious games for the Elicitation of way-finding behaviours in emergency situat...
Almeida, João Emílio; Jacob, João Tiago Pinheiro Neto; Faria, Brígida Mónica; Rossetti, Rosaldo J. F.; Coelho, António LecaUnderstanding human behaviour in emergency evacuation from buildings is of utmost importance for fire safety designers, architects and engineers as they elaborate on strategies to improve the emergency paths to exits. This paper describes an experiment designed to elicit human behaviour when facing the urgent need of exiting a room of an unknown building. This test is part of a methodological approach that aims...
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...
