A weakness with the Swedish Transport Administration’s model for long-distance trips is that it onlyallows for one mode of transportation per trip. A long-distance trip usually consists of several modesof transportation, while the current model does not allow modelling of, for example, a flight with aconnecting car, bus or train transfer. This is problematic as a significant part of the generalized costof travel can be derived from an access trip.The master thesis has been devoted to studying how a model for choice of access mode anddeparture airport can be designed. The work has been limited to study long-distance trips starting inStockholm county, carried out by residents of the county. The airport choice has been limited toArlanda and Bromma Airport.In a literature review, the underlying mathematical theories which the project is based on arepresented. The theory originates from the work on discrete choice models by Daniel McFadden,which later was further developed and summarized by Kenneth Train. By studying previous researchdealing with modelling of access mode and airport choice, it can be concluded that there is noobvious approach to model design, apart from the fact that the model should be based on the logittheory.The observations on which the model is estimated are retrieved from travel surveys conductedduring 2011-2016. A cost estimate for the modes of travel included in the model has been donemanually. Travel times for all modes have been generated using the Swedish TransportAdministration’s regional base model for Stockholm County dated 2014, using the macro simulationsoftware Emme.Out of all the estimated models, one model is presented as the best and final one. It is a multinomiallogit model divided into two segments, one for business travelers and one for private travelers. Themodel is analyzed by calculating value of time, cost- and time elasticity for each of the alternatives inthe choice set. For some of the alternatives, the value of time is relatively high, which is addressed inthe concluding discussion.

Procura compreender as consequências da atual política de reduçäo de custos (que no caso da Marinha Mercante vem privilegiando, näo a modernizaçäo tecnológica e sim o corte no número de tripulantes) para a saúde/saúde mental dos trabalhadores. O trabalho de campo foi realizado a bordo de navio petroleiro da Frota Nacional de Petroleiros (FRONAPE), durante percurso compreendido entre Angra dos Reis (Rio de Janeiro/Brasil) e Cape Town (Africa do Sul), no período de 25 de maio a 08 de junho de 1998, sendo realizadas observaçöes das atividades desenvolvidas e das relaçöes de vida e trabalho da tripulaçäo a bordo, bem como entrevistas individuais com onze tripulantes, que foram analisadas tendo como principal abordagem teórico metodológica a psicodinâmica do trabalho. Constatou-se que a família assume papel importante na vida do trabalhador, sendo o seu distanciamento a principal fonte de sofrimento psíquico e debruçar-se sobre o trabalho o principal mecanismo defensivo utilizado pelos trabalhadores para o seu enfrentamento. Esse sofrimento está sendo intensificado pelo näo reconhecimento desse dar-se de si no trabalho e pela queda na remuneraçäo salarial. Contudo, o trabalhador embarcado a partir do prazer gerado pelo uso de sua criatividade e do bom humor na realizaçäo da tarefa, vem conseguindo näo sucumbir ao sofrimento, mantendo-se dentro do domínio da normalidade. / The present study deals with the maritime labor, particularly the work of those on board long distance ships, whose crews spend long periods far away from the family and social intimacy, which leads to psychic suffering. It tries to understand the consequences of the current policy of cutting of costs (which in the case of the Merchant Navy has been privileging the cuts in the number of crew members in detriment of technological modernization) for the health/mental health of the workers. The field work was carried out on board an oil tanker owned by the National Fleet of Oil Tankers (FRONAPE), during the route between Angra dos Reis (Rio de Janeiro/Brazil) and Cape Town (South Africa), from May 25th to June 8th, 1998, during which the carried out activities, the life and work relationships of the crew on board, were observed, as well as individual interviews with eleven members of the crew, that were analyzed having as its main theoretical-methodological approach the Psychodynamics of Labor. Family plays an important role in the worker's life, and staying away from them is the main source of physical suffering. Therefore, full dedication to work is the main defense mechanism used by the workers in order to face the problem. Such suffering is being intensified by the non-recognition of this dedication to work and by a drop of the salary remuneration. However, the worker on board, as of the fun generated by the use of his creativity and good humor on the carrying out of his task, has been able to resist the suffering, staying within the domains of what is considered to be normal.
