No. of bitstreams: 1 DissVLSO.pdf: 839524 bytes, checksum: 71c434ddb5669697de4e49af9bd3b7ba (MD5) Previous issue date: 2016-04-13 / Não recebi financiamento / Brazil's cities in recent decades have a predominance of car use as children's mode of transport to school. In carrying out the route home-school by motorized modes children practice less physical activity to the detriment of health. Policies developed in schools can play an important role in determining how students travel to school. In this context, this research aims to identify the factors that influence the perception of managers about using the walk to access the school. The focuses of the research are the municipal and private elementary schools 1. The case study was conducted in the city of São José do Rio Preto. Data collection was carried out with the school managers (directors, coordinators and teachers) through questionnaires on travel behavior of the students, information on any activities at school to teach students to behave in traffic, opinions of management on the relationship between physical activity and health of children, children's ability to to walk to school, the barriers surrounding the school and attitude of managers regarding the use of different modes of transport and the impact of vehicle traffic in urban . The results showed that the estimation of directors and coordinators on the modes of transport used by students does not differ from a survey conducted by teachers significantly, and in private schools motorized individual transport is the most used by students and public schools over half of students walk or use public transportation to school. It was found that the traffic behavior on teaching is applied in all schools, although the directors and coordinators are more likely to say that the activities are carried out in your school. The school managers have a positive perception of the importance of physical activity, with acceptance rates above 90%. There is no consensus about the best age and abilities of children to make safe decisions alone and analysis on the perception of managers of barriers around the schools that may hinder access to foot it was found that about half of the managers have positive about the quality of the environment around the schools, but other managers have indifferent opinion about the quality of the environment. Regarding the use of different modes of transport it was observed that attitudes regarding the use of buses are in general negative, more than half of managers are indifferent to automobile use and favorable to the use of the walk. In the manager's attitude regarding the impact of vehicle traffic in urban areas the vast majority of managers are concerned about the impact of traffic on the environment. Perceptions regarding the active mobility should be worked through school policies to improve students' skills as pedestrians and through public policies to improve the environment in the school environment and encourage the use of active modes of transportation. / As cidades brasileiras nas ultimas décadas vem apresentando um predomínio do uso do automóvel como modo de transporte das crianças para a escola. Ao realizarem o percurso casa-escola por modos motorizados as crianças praticam menos atividades físicas com prejuízo para a saúde. Políticas desenvolvidas nas escolas podem desempenhar um papel importante na determinação do modo como os estudantes viajam para a escola. Neste contexto, esta pesquisa visa identificar quais os fatores que influenciam na percepção dos gestores sobre a utilização da caminhada para acesso a escola. O foco da pesquisa são as escolas municipais e particulares de ensino fundamental 1. O estudo de caso foi realizado na cidade de São José do Rio Preto. A coleta de dados foi realizada junto aos gestores escolares (diretores, coordenadores e professores) através de questionários sobre comportamento de viagem dos alunos da escola, informações sobre eventuais atividades desenvolvidas na escola para ensinar aos alunos com se comportar no trânsito, opiniões dos gestores sobre o relacionamento entre atividades físicas e saúde das crianças, a habilidade das crianças para caminharem até a escola, as barreiras existentes no entorno da escola e atitude dos gestores com relação à utilização dos diferentes modos de transporte e ao impacto do tráfego de veículos no meio urbano. Os resultados mostraram que a estimativa dos diretores e coordenadores sobre os modos de transporte utilizados pelos alunos não difere significativamente do levantamento realizado pelos professores, sendo que nas escolas privadas o transporte individual motorizado é o mais utilizado pelos alunos e nas escolas públicas mais da metade dos alunos caminham ou utilizam o transporte coletivo para a escola. Verificou-se que o ensino sobre comportamento no trânsito é aplicado em todas as escolas, embora os diretores e coordenadores sejam mais propensos a afirmar que as atividades são realizadas em sua escola. Os gestores escolares têm percepção positiva sobre a importância da atividade física, com taxas de aceitação acima de 90%. Não há um consenso sobre a melhor idade e as habilidades das crianças para tomar decisões seguras sozinhas e nas análises sobre a percepção dos gestores das barreiras existentes no entorno das escolas que podem dificultar o acesso a pé constatou-se que cerca da metade dos gestores tem opinião positiva sobre a qualidade do ambiente no entorno das escolas, porém os demais gestores possuem opinião indiferente quanto a qualidade do ambiente. Com relação à utilização dos diferentes modos de transporte observou-se que as atitudes com relação ao uso do ônibus são em geral negativas, mais da metade dos gestores são indiferentes ao uso do automóvel e são favoráveis às caminhada. Na atitude do gestor com relação ao impacto do tráfego de veículos no meio urbano a grande maioria dos gestores é preocupada com o impacto do tráfego no meio ambiente. As percepções com relação à mobilidade ativa devem ser trabalhadas através de políticas escolares para melhorar as habilidades dos alunos quanto pedestres e através de políticas públicas para melhorar o ambiente no entorno escolar e incentivar o uso dos modos ativos de transporte.

Åkers Sweden AB - Outbound Logistics : Reduction of Environmental Effects / Åkers Sweden AB - Utgående Distribution : Reducering av miljöpåverkan

Gustafsson, Anders, Larsson, Carina, Sundström, Henric January 2009 (has links)
<p><strong>Summary</strong></p><p>Environmental issues have become increasingly more important the last decade. It is of great importance to reduce emissions of green house gases (GHG) and the transport sector contributes to a large part of GHG emissions. The transport sector is the only sector that actually has increased the emissions during the last decade. This is a result of a growing economy and an increased demand of both carriages of passengers as well as freight transports. To reduce GHG emissions there is a need of smart, effective logistics solutions and new technologies. This thesis will contain a review of Åkers Sweden AB’s outbound logistics of rolls. The aim of this thesis is to identify environmental improvements without increasing further costs. A questionnaire for environmental evaluation of transport suppliers will also be developed in this thesis. Initial question formulations of this thesis are:</p><p> </p><p>1. What are the environmental effects of the different modes of freight transports that are used in the case of Åkers Sweden AB?

This model is developed by the Network for Transport and Environment (NTM). Examined modes of transport are road, rail and sea transports. Both theory and result in this thesis demonstrate that rail transports should be preferred to road transports from an environmental point of view. A disadvantage of rail transports is longer transport time in most cases. Longer transport time contribute to higher capital cost of goods during transit. Another disadvantage is that rail transports are limited between terminals or that customers have an industrial railway track.

This involves less impact than current alternative. The new alternative will decrease freight costs by 37 %. However, an increased capital cost by 84 % has been identified due to additional transportation time that is required for the alternative suggested. Transport costs are poorly connected to the real cost on the society. Governments throughout the world need to encourage transport buyers to choose more environmentally adapted alternatives by using management control measures. Also, a questionnaire for environmental evaluation of transport suppliers has been developed. It contains questions of the environmental organisation of the company, how they work with education of staff and reporting of environmental effects.</p> / <p><strong>Sammanfattning</strong></p><p>Under senare tid har miljöfrågor fått en alltmer framträdande roll i samhällsdebatten.

Zwangsmobilität und Verkehrsmittelorientierung junger Erwachsener / Forced mobility and orientation towards transport modes of young adults: Creation of a typology

Wittwer, Rico 23 January 2015 (has links) (PDF)
In der Mobilitätsforschung entstand in den vergangenen Jahrzehnten eine breite Wissensbasis für das Verständnis von Verkehrsursachen und Zusammenhängen, die das Verkehrsverhalten determinieren. Mit der Entwicklung von Verkehrsmodellen lag das Forschungsinteresse zunächst primär bei Ökonomen und Ökonometrikern sowie Verkehrsingenieuren. Bald kamen andere Wissenschaftsbereiche wie die Psychologie oder die Geowissenschaften hinzu, welche sich in der Folge zunehmend mit dem Thema Mobilität befassten und die zur Erklärung des menschlichen Verhaltens ganz unterschiedliche Methoden und Maßstäbe nutzten. Heute versuchen zumeist handlungsorientierte Ansätze, auf Individualebene, Faktoren zu bestimmen, die Aufschluss über die Verhaltensvariabilität in der Bevölkerung geben und damit einen möglichst großen Beitrag zur Varianzaufklärung leisten. Werden Einflussfaktoren in geeigneter Weise identifiziert und quantifiziert, können Defizite und Chancen erkannt und das Verhalten steuernde Maßnahmen entworfen werden. Mit deren Hilfe wird ungewollten Entwicklungen entgegengesteuert. Junge Erwachsene stellen aufgrund ihrer sehr unterschiedlichen Phasen im Lebenszyklus, z. B. gerade anstehender oder abgeschlossener Ausbildung, Umzug in eine eigene Wohnung, Familiengründung, Neuorientierung in Arbeitsroutinen oder das Einleben in ein anderes Lebensumfeld einer fremden Stadt, intuitiv eine sehr heterogene Gruppe dar. Die Modellierung des Verhaltens ist für diese Altersgruppe besonders schwierig. Aus der Komplexität dieser Problemstellung heraus ist ersichtlich, dass fundierte Analysen zur Mobilität junger Erwachsener notwendig sind, um verkehrsplanerische Defizite aufzudecken und Chancen zu erkennen. Der methodische Schwerpunkt des Beitrages liegt auf der Bildung einer Typologie des Verkehrsverhaltens junger Erwachsener. Die verwendete Datengrundlage ist das „Deutsche Mobilitätspanel – MOP“. Dabei wird der Versuch unternommen, zunächst Variablen aller relevanten Dimensionen des handlungsorientierten, aktivitätsbasierten Verkehrsverhaltens zusammenzustellen und für eine entsprechende Analyse aufzubereiten. Im Anschluss werden geeignete und in den Sozialwissenschaften erprobte Verfahren zur Ähnlichkeitsmessung eingesetzt, um möglichst verhaltensähnliche Personen zu typologisieren. Im Weiteren finden konfirmatorische Analysetechniken Anwendung, mit deren Hilfe Verhaltenshintergründe erklärt und inferenzstatistisch geprüft werden. Als Ergebnis wird eine clusteranalytische Typologisierung vorgestellt, die im Anschluss anhand soziodemografischer Indikatoren und raumstruktureller Kriterien der Lagegunst beschrieben wird. Aufgrund der gewonnenen Erkenntnisse können objektive und im Idealfall quantifizierbare, d. h. prognosefähige Merkmale zur Bildung verkehrssoziologischer und weitgehend verhaltensähnlicher Personengruppen genutzt werden. / Over the last few decades of mobility research, a wide base of knowledge for understanding travel determinants and causal relationships in mobility behavior has been established. The development of travel models was at first of interest primarily to economists and econometricians as well as transportation engineers. They were soon joined by other scientific areas such as psychology or the geosciences, which as a result increasingly addressed the theme of mobility and used quite different methodologies and criteria for explaining human behavior. Today, activity-oriented approaches generally attempt to determine individual-level factors that provide information on behavioral variability within the population, thereby contributing greatly to explaining variances. If explanatory factors can be properly identified and quantified, then deficiencies and opportunities can be recognized and measures for influencing behavior can be conceptualized. With their help, undesirable developments can be avoided. Because of their highly differing stages in life, e.g. upcoming or recently completed education, moving into their own apartment, starting a family, becoming oriented in a work routine or adapting to a new environment in a different city, young adults are intuitively a very heterogeneous group. Modeling the behavior of this age group is particularly difficult. This problem makes it clear that founded analysis of the mobility of young adults is necessary in order to recognize deficiencies and opportunities in transportation planning. The methodological focus of this work is on creating a typology of young adults’ travel behavior. The base data is from the “Deutsches Mobilitätspanel – MOP” (German Mobility Panel). An attempt is made to gather and prepare all relevant dimensions of decision-oriented, activity-based travel behavior for a corresponding analysis. Afterward, appropriate and proven methods from the social sciences are used to test for similarity in order to identify groups of persons which are as behaviorally homogeneous as possible. In addition, confirmatory data analysis is utilized which helps explain and test, through inferential statistics, determinants of behavior. The resulting typology from the cluster analysis is presented and followed by a description using sociodemographic indicators and spatial criteria of accessibility. The findings make it possible to use objective and, ideally, quantifiable and therefore forecastable characteristics for identifying sociological population groups within which similar travel behavior is displayed.
