Impactos da implantação de medidas de gerenciamento da mobilidade em uma área urbana com múltiplos pólos atratores de viagens

Schmitt, Rafael da Silva January 2006 (has links)
Nesta dissertação são analisados os impactos da implantação de medidas de gerenciamento da mobilidade (GM) em uma área urbana localizada na cidade de Porto Alegre com vários pólos atratores de viagens. O GM – abordagem européia do gerenciamento da demanda de viagens – busca uma mobilidade urbana mais sustentável, tentando influir no comportamento de viagem das pessoas. São discutidos seu conceito, suas ferramentas, medidas e serviços de transporte, incluindo exemplos de implantação no mundo. Foram escolhidas duas medidas de GM, dentro de um pacote de medidas a serem implantadas pelo projeto Moviman na área de estudo, localizada na zona leste de Porto Alegre, onde atualmente há uma universidade (PUCRS), hospitais, um shopping center, hipermercados, entre outros estabelecimentos. A primeira medida analisada foi a carona programada, uso compartilhado de um automóvel com divisão de custos. Foi feita uma pesquisa com alunos da PUCRS para verificar sua receptividade em relação a esta medida. A partir dos resultados desta pesquisa, foi avaliado o possível impacto da implantação desta medida no tráfego da área de estudo. Também foi feita pesquisa com trabalhadores de uma empresa local para comparar a receptividade a esta medida por usuários diferentes. A segunda medida foi a implantação de um Sistema de Informação ao Usuário (SIU) de transporte coletivo em duas paradas de ônibus, através da realização de pesquisas de importância e satisfação, para priorizar as informações e de uma pesquisa final de satisfação e análise de intenção de mudança modal causada pelo SIU. Os resultados demonstram que a carona programada é uma medida com boa receptividade entre os grupos-alvo pesquisados, que causa uma melhora das condições de tráfego locais. E um novo SIU nas paradas de ônibus é uma medida de qualificação do transporte coletivo com um bom potencial de atração de novos usuários e de fidelização dos atuais. Portanto, comprovouse o impacto positivo da implantação destas medidas de GM em uma cidade brasileira, pois ambas atenderam aos objetivos de uma mobilidade urbana sustentável sem a limitação da mobilidade das pessoas. / This dissertation presents the evaluation of the impacts produced by mobility management (MM) measures introduced in an urban area, with many trip production centers, located in Porto Alegre city, southern Brazil. The MM, European approach of travel demand management, aims a more sustainable urban mobility, trying to influence in the travel behavior of people. Their concepts, tools, measures and transport services are discussed, including other implantation examples worldwide. Two MM measures were chosen within a package of measures that would be implemented by the Moviman project in the studied area. The selected area, situated in the east zone of Porto Alegre, holds a university (PUCRS), hospitals, a shopping center, among others commercial establishments. The first analyzed measure was carpooling, shared use of an automobile with division of costs, using the application of a survey with university students, from PUCRS, to verify their receptivity in relation to this alternative transportation mode. The survey results were used for the analysis of possible impacts of this measure in the traffic of the study area. A survey with workers of a local company was done to compare the receptivity with these measures in distinct users. The second measure was the installation of a public transport user information system (UIS) in two bus stops, using importance and satisfaction surveys in order to define information priorities, and a final survey of satisfaction and analysis of modal change intention caused by UIS. The results demonstrate that carpooling is a transport measure with good receptivity among the target groups, and improves the local traffic conditions. Moreover the installation of new UIS in bus stops is a measure of qualification of the public transportation with good potential for attraction of new users and consolidation of actual users. Therefore, the impacts of MM measures in a Brazilian city were positive, considering that both measures reach the goal of sustainable mobility without limiting people mobility.

Investigating end-user acceptance of autonomous electric buses to accelerate diffusion

Herrenkind, Bernd, Brendel, Alfred Benedikt, Nastjuk, Ilja, Greve, Maike, Kolbe, Lutz M. 08 September 2021 (has links)
To achieve the widespread diffusion of autonomous electric buses (AEBs) and thus harness their environmental potential, a broad acceptance of new technology-based mobility concepts must be fostered. Still, there remains little known about the factors determining their acceptance, especially in the combination of vehicles with alternative fuels and autonomous driving modes, as is the case with AEBs. In this study, we first conducted qualitative research to identify relevant factors influencing individual acceptance of autonomously driven electric buses. We then developed a comprehensive research model that was validated through a survey of 268 passengers of an AEB, operated in regular road traffic in Germany. The results indicate that a mix of individual factors, social impacts, and system characteristics determine an individual’s acceptance of AEBs. Notably, it is important that users perceive AEBs, not only as advantageous, but also trustworthy, enjoyable, and in a positive social light. Our research supplements the existing corpora by demonstrating the importance of individual acceptance and incorporating it to derive policy implications.

Mediální obraz pražské dopravy / Media Image of Transport in Prague

Morongová, Denisa January 2018 (has links)
This diploma thesis contributes to sustainable transport in Prague. It analyses media texts from six selected Czech printed newspapers (Blesk, Mladá fronta Dnes, Pražský deník, Metro, Hospodářské noviny, Právo) by using the theoretical and methodological strategy of critical discourse analysis by Norman Fairclough. These texts were found through media database Anopress IT by using keywords about sustainable transport in the capital city of Prague in years 2010 till 2018. This thesis is divided into four main parts. The theoretical part is dedicated to the terms of mobility management, the social construction of reality and discourse. The methodological part is focusing on discourse analysis, critical discourse analysis and the approach by Norman Fairclough. The analysis identified five topics in the discourse of sustainable transport in Prague - electromobility, public transport, foot traffic, urban cycling, and Sustainable Mobility Plan. Sustainable mobility in Prague is presented in a context of the polluted environment which should be solved by "ecologically, environment- friendly, clean". The most media texts were dedicated to public transport and electromobility. Just one text was about foot traffic as a sustainable type of mobility. Participants were mostly from Prague city hall, however, not...

Social participation for sustainable mobility : The effects of digital transformation on mobility behavior

Guerreiro Augusto, Marc January 2020 (has links)
Overall traffic in Germany is constantly increasing. Automobiles account for 57 percent of all trips in the country (BMVI, 2018). Steady population growth, urban agglomeration, and sprawl of cities contribute significantly to this trend. Simultaneously, the rise of digital services is progressively complementing travel by route planning, navigation, and ticketing. Therefore, a redesign and reinterpretation of the traditional understanding of the mobility landscape is required. The purpose of this work is twofold. First, to investigate the effects of digital transformation on people’s mobility behavior in public space, arguing for ecosystems in blended space being a consequence of the digital transformation at large. Second, to explore how social participation can lead to societal change for sustainable travel in the context of digital transformation. Digital technology has blurred the boundaries between physical and digital. Although physical and digital spaces are treated as separate parts, the former relates to the success of the latter. Qualitative interviewing was applied to systematically create an understanding about key actors’ roles and interdependencies as well as their perspective on how digital technologies modify today’s mobility landscape. This work concludes that the digital transformation allows individuals to influence travel demand purposefully. The system’s underlying structure reveals travel as purposive demand, a pattern extending the understanding of travel as a derived demand and valued activity. The Multi-Layered Participatory Process (MLPP), developed on the basis of the study’s findings, provides means to enable large scale social acceptance for sustainable mobility behavior.

Hållbar Mobilitet i Rosendal, Uppsala : En studie om Rosendalsbornas mobilitetspraktiker och inställningar

Zachari, Vasiliki January 2022 (has links)
Den här uppsatsen undersöker boendes mobilitetsmönster och uppfattningar i relation till hållbar mobilitet i Rosendal, Uppsala. Syftet med uppsatsen är att utreda i vilken grad de boende i Rosendal använder hållbara färdmedel i sin vardagliga mobilitet i relation till områdets fysiska, institutionella, sociala och kulturella förhållanden. För att genomföra undersökningen har både kvantitativa och kvalitativa metoder använts. Data har samlats in utifrån en enkät, varpå olika typer av statistiska analyser har uppförts. En intervjustudie har ytterligare henomförts för att samla in djupare information som leder till kompletterad förstålse i relation till de boendes mobilitetspraktiker. För att tolka resultatet har teoretiska utgångspunkter inom transportgeografin använts vilka är anpassade till det så kallade mobilities paradigmet. Paradigmet lyfter fram aspekter som främst är sammankopplade med den sociala och kulturella kontexten i relation till mobilitetspraktiker. Den här uppsatsen försöker belysa hur den fysiska och institutionella kontexten förknippas med den sociala och kulturella i frågan om hållbar mobilitet. Det hållbara mobilitetsbeteende är snarare ett resultat av den fysiska kontexten än de implmenterande mobilitetstänsterna. Uppsatsen lyfter fram att även den sociala och kulturella kontexten måste tas hänsyn till. Det anses att ett barn-, ålders- och genusperspektiv måste integreras i de relevanta policyerna på ett bättre sätt. Uppsatsen pekar även på att kommunikationen av de befintliga mobilitetstjänsterna till de boende även skulle kunna förbättras.

Det trafkstrategiska arbetet för att främja hållbar mobilitet : En kvalitativ studie av två stora svenska kommuner / The traffic strategic work to promote sustainable mobility : A qualitative study of two large Swedish municipalities

Söderqvist, Filip, Alder, Eric January 2022 (has links)
The transport sector currently accounts for a third of climate-affecting emissions in Sweden, which must be reduced in order for the government's target for climate emissions to be reduced by 70 percent by 2030 and for zero emissions to be achieved by 2045. This is done by encouraging sustainable modes of transport. This paper aims to investigate which policy instruments Malmö and Gothenburg use to encourage sustainable mobility. This is done on the basis of five qualitative interviews with the municipalities and the Swedish Transport Administration, as well as document analyzes of the municipalities traffic strategies. The results show that the main instruments focus on providing more space for cycling, walking and public transport, as well as reducing opportunities for car use, which is mainly done by limiting parking opportunities for cars. However, there are differences in the municipalities ability to implement sustainable mobility, which depends on the municipalities transport history and urban design, but also the ability to change their citizens' travel behavior.

Approaching sustainable mobility utilizing graph neural networks

Gunnarsson, Robin, Åkermark, Alexander January 2021 (has links)
This report is done in collaboration with WirelessCar for the master of science thesis at Halmstad University. Many different parameters influence fuel consumption. The objective of the report is to evaluate if Graph neural networks are a practical model to perform fuel consumption prediction on areas. The model uses a partitioning of geographical locations of trip observations to capture their spatial information. The project also proposes a method to capture the non-stationary behavior of vehicles by defining a vehicle node as a separate entity. The model then captures their different features in a dense layer neural network and utilizes message passing to capture context about neighboring nodes. The model is compared to a baseline neural network with a similar network architecture as the graph neural network. The data is partitioned to define an area with Kmeans and static gridnet partition with and without terrain details. This partition is used to structure a homogeneous graph that is underperforming. The practical drawbacks of the initial homogeneous graph are inspected and addressed to develop a heterogeneous graph that can outperform the neural network baseline.
