A avaliação 360º : percepções dos professores do Programa de Ensino Integral /

Barbosa, Mayara Letícia Calixto dos Santos January 2019 (has links)
Orientador: Regiane Helena Bertagna / Resumo: A presente pesquisa tem o objetivo de analisar as percepções dos professores que fazem parte do Programa de Ensino Integral do Estado de São Paulo (PEI) e que participam da avaliação de desempenho que faz parte do PEI, denominada “Avaliação 360 graus”, colocando a educação e as relações desses profissionais sob a ótica do gerencialismo, tendo como principais objetivos a obtenção do alcance de metas na lógica do mercado empresarial. Para que isso ocorra, é necessário medir e avaliar o trabalho que é realizado pelos profissionais e se os mesmos correspondem com o perfil esperado pela escola para garantir resultados satisfatórios. Nesse contexto, a Avaliação de Desempenho, utilizada no setor administrativo, é introduzida no ambiente escolar, avaliando os professores através de um processo que, em teoria, deve colaborar com sua formação profissional, com a reflexão sobre seu trabalho e o apontamento de melhorias. A pesquisa foi desenvolvida com o aporte de referências bibliográficas tanto na área de educação quanto de administração, além dos documentos que embasam a implantação e o funcionamento do Programa de Ensino Integral do Estado de São Paulo, Programa esse que utiliza como Avaliação de Desempenho um método específico chamado de “Avaliação 360 graus”. Como foco maior dessa pesquisa, a análise do instrumento inserido no PEI se dá através das percepções de seis professores com relação ao instrumento adotado para avaliar seu desempenho e ao processo de avaliação.

Simulation Methods for Mixed Legacy-Autonomous Mainline Train Operations

Morey, Emily J., Wilson, R. Eddie, Galvin, Kevin 22 June 2023 (has links)
We introduce and demonstrate a simple and efficient method for simulating mixtures of legacy and autonomous trains. The method generalises an earlier simulation that we developed for legacy-only operations, in which trains run according to fixed-block signalling rules. Autonomous trains, which use moving-block signalling rules, are incorporated into this framework by employing an overlapping set of short virtual fixed-blocks. Safe occupancy is then maintained by using shadowing rules that link the two sets of blocks. The paper gives relevant rail background, details of the proposed simulation rules, and demonstrates exemplar solution trajectories. The simulation technique is validated both in terms of maintaining safe occupancy and providing a close approximation of the true continuous-space dynamics of autonomous leader-follower pairs. At the Dresden meeting, a variety of interesting mixed-fleet capacity results will also be presented.

Can Dedicated Lanes for Automated Vehicles on Urban Roads Improve Traffic Efficiency?

Tilg, Gabriel, Krause, Sabine, Stueger, Philipp N., Bogenberger, Klaus 22 June 2023 (has links)
Connected and automated vehicles (CAVs) will behave fundamentally differently than human drivers. In mixed traffic, this could lead to inefficiencies and safety-critical situations since neither human drivers nor CAVs will be able to fully anticipate or predict surrounding traffic dynamics. Thus, some researchers proposed to separate CAVs from conventional vehicles by dedicating exclusive lanes to them. However, the separation of road infrastructure can negatively impact the system’s capacity. While the effects of CAV lanes were addressed for freeways, their deployment in urban settings is not yet fully understood. This paper systematically analyzes the effects of CAV-lanes in an urban setting accounting for the corresponding complexities. We employ microscopic traffic simulation to model traffic flow dynamics in a detailed manner and to be able to consider a wide array of supply-related characteristics. These concern intersection geometry, public transport operation, traffic signal control, and traffic management. Our study contributes to the existing literature by revealing the potential of CAV lanes in an urban setting while accounting for the behavioral and topological complexities. The results of this study can support decision-makers in the design of future urban transportation systems and to prepare cities for the upcoming era of automation in traffic.

GLOSA System with Uncertain Green and Red Signal Phases

Typaldos, Panagiotis, Koutsas, Petros, Papamichail, Ioannis, Papageorgiou, Markos 22 June 2023 (has links)
A discrete-time stochastic optimal control problem was recently proposed to address the GLOSA (Green Light Optimal Speed Advisory) problem in cases where the next signal switching time is decided in real-time and is therefore uncertain in advance. However, there was an assumption that the traffic signal is initially red and turns to green, which means that only half traffic light cycle was considered. In this work, the aforementioned problem is extended considering a full traffic light cycle, consisting of four phases: a certain green phase, during which the vehicle can freely pass; an uncertain green phase, in which there is a probability that the traffic light will extend its duration or turn to red at any time; a certain red phase during which the vehicle cannot pass; and an uncertain red phase, in which there is a probability that the red signal may be extended or turn to green at any time. It is demonstrated, based on preliminary results, that the proposed SDP (Stochastic Dynamic Programming) approach achieves better average performance, in terms of fuel consumption, compared to the IDM (Intelligent Driver Model), which emulates human-driving behavior.

Learning from Covid: How Can we Predict Mobility Behaviour in the Face of Disruptive Events? – How to Investigate the Mobility of the Future

Papendieck, Paul, Bäumler, Maximilian, Sotnikova, Anna, Hirrle, Angelika 23 June 2023 (has links)
Introduction: With the beginning of the COVID-19 outbreak and the restrictions put in place to prevent an uncontrolled spread of the virus, the circumstances for daily activities changed. A remarkable shift in the modal split distribution was observed [Ank21]. Moreover, the changes in mobility during the COVID-19 pandemic had multiple impacts on road traffic [Yas21]. By now, several researchers have looked at the impact of COVID-19 as a disruptive event on mobility behaviour. This workshop within the 4th Symposium on Management of Future Motorway and Urban Traffic Systems aimed to discuss insights from these research projects and how they enable experts to transfer this newfound knowledge to future disruptive events such as climate change, rising energy costs and events related to a possible energy transition. Thus, the research question this workshop investigated reads as follows: What can we learn from the pandemic to be able to predict how different future disruptive events can shape the mobility of tomorrow?

En resa till Antarktis : En kvalitativ studie om att resa med VR / A trip to Antarctica : A qualitative study on travelling with VR

Höber, Viktor January 2022 (has links)
Under coronapandemin blev det nästan omöjligt att resa, vilket ledde till att fler människor försökte hitta andra sätt att fly vardagen och upptäcka världen på. En teknik som kom i fokus då var Virtual Reality (VR) som skapade möjligheten att resa virtuellt. Det här är en deskriptiv studie som syftar till att ge en djup förståelse för hur en resa i VR upplevs av sina användare. I studien genomfördes ett experiment där fem personer testade VR-mjukvaran National Geographic Explore och genomförde en virtuell resa till Antarktis. Hårdvaran som användes i studien var Oculus Quest (gen1). Deltagarna intervjuades om sina upplevelser av resan och den data som insamlades från intervjuerna analyserades baserat på Giorgis 5 analyssteg. Slutsatser som studien kommit fram till är att tekniken fortfarande behöver finjusteras då den inte lever upp till de förväntningar som användarna har gällande bild, grafik eller kontroller. Resultatet pekar dock på att mediet skapar en känsla av verklighet som användaren ibland inte kan skilja från verkligheten. De tekniker som framför allt skapar den känslan är enligt respondenterna 360 graders filmteknik med 6 degrees of freedom, förstapersonsperspektivet samt interaktionen. En slutsats som dragits är att ju fler sinnen som tekniken lyckas aktivera desto verkligare känns upplevelsen. Experimentdeltagarna kändes sig som mest integrerade i tekniken under de tillfällen i VR-resan som de använde hela kroppen. Resultatet från den här studien pekar på att en anledning till att människan reser, både i VR och fysiskt, är för att fly vardagen, en typ av eskapism. / During the Corona pandemic it became almost impossible to travel. This led to a search for alternative ways of escaping the everyday life and to explore the world. In the light of this the technology Virtual Reality (VR) came into focus. This is a descriptive study who aims to give a deep understanding of how travelling in virtual reality are experienced by its users. In the study an experiment was made where 5 persons tried out the VR-app National Geographic Explore where they took a virtual trip to Antarctica. The hardware that was used in the study was Oculus Quest (gen1). The participants were interviewed about their experiences of the trip. The data that was collected from the interviews was analyzed based on the 5 steps method of Giorgi. Conclusions that where made is that the technology still need adjustments because it does not live up to the user’s expectations about the graphics, the photo, or the controllers. The result, however, indicates that the medium creates a sense of reality, a sense which the users sometimes can’t distinguish from the physical reality. The technologies that the users found most important to create the feeling of immersion and sense of reality was the 360 degrees filming with 6 degrees of freedom, the first-person perspective, and the interaction. A conclusion that’s been made is that the more senses the technology can activate the more integrated and closer to reality does the users feel. The situation when the users felt most integrated in the medium was during the activities when the participants used their bodies and not only their eyes. The result of this study indicates that one reason why people travel, both in VR and physical, is to escape everyday life, a type of escapism.
