Abstract

O principal objetivo deste trabalho foi o desenvolvimento de um sistema informatizado para o auxílio na escolha modal pelos usuários de transporte público. Neste sistema, as alternativas a considerar e soluções geradas devem se basear nas solicitações do usuário e poderão ser usadas para o planejamento tático e/ou estratégico do sistema de transporte considerado. O sistema foi modelado para solução através do algoritmo de fluxo em rede Label Correcting, capaz de lidar com esse problema multimodal, implementado em uma linguagem de programação orientada a objetos. O sistema foi concebido como uma aplicação de internet e, embora seja voltado para um sistema de transporte genérico, foi aplicado e testado com base nas alternativas de transporte disponíveis e malha de ruas da Cidade Universitária Armando de Salles Oliveira. The main target of this master of science research is the development of a tool to help on modal selection by the public transportation users, which will be implemented as an eletronic information system.Since the infomation must be provided in real time to the user,it is important to the system to be fast and easy to use.It is also a requirement that the system presents options and information to help the user on the selection of the best choice among all possible ones. The alternatives to be considered and generated solutions shall be based on the user requests related to origin and destination of the desired trip. The requests will be stored and could be used for tactic and/or strategic planning of the concerned system of transport. This multimodal problem will be modeled to be solved with the Label Correcting network flow algorithm and implemented using an object oriented language. Although addressed to a generic transport system,it will be implemented and tested based on the available transport alternatives and street mesh of the Cidade Universitaria Armando de Salles Oliveira. The system may be available to users through internet.

Abstract

International audience; Most of current managerial studies on Autonomous Vehicles (AVs) focus on future social and economic impacts of privately-owned AVs. In contrast, the present study aimed on carrying out an in-depth benchmark on successful experimentations with Autonomous Shuttles for Collective Transport (ASCTs), identifying the most relevant social and economic findings as well as understanding how such results may contribute to future projects and trials. The research was designed as an in-depth qualitative benchmark of exploratory and descriptive nature on three selected European projects with ASCTs: CityMobil2, GATEway, SHOJOA. Results mainly focused on the trials' social aspects (e.g., user acceptance, trust, willingness to use and, shuttles' interactions with mixed-traffic). Economic impacts were not widely disclosed and/or explored (results were mainly centered on users' willingness to pay and potential to reduce fares). Thereby, we advocate that economic aspects shall not be considered as "ceteris paribus" while measuring user acceptance. From the perspective of social sciences, the study sheds light into what is currently being evaluated on ASCTs' trials. Results are relevant for future ASCTs projects to focus on neglected aspects and also to improve upon the trials' successful results in a sense that, to date, no current studies were found aiming to understand and evaluate the social and economic impacts of ASCTs deployments.
