Many cities including Stockholm gave highways as a solution to traffic congestion. Essingeleden motorway is part of European route E4 and today is the busiest road in Sweden. It connects the north and the south part of the country, by crossing islands of central Stockholm. The result of that is a huge swath through the city, that splits the island of Kungsholmen into two pieces, creating isolated neighbourhoods and huge traffic jams. I believe that Essingeleden is reaching its end as a highway, especially since Stockholm is preparing to become a fossil fuel-free city until 2050. Last, the Stockholm bypass project will be able to replace Essingeleden outside the city centre, therefore the Essingeleden worth is being called into question.  Through my diploma project I will propose the transformation of Essingeleden motorway into surface streets, boulevards and parks to improve the accessibility and the street network. Furthermore, my solution will connect the isolated neighbourhoods by healing the local street networks and improve the regional traffic dispersion. Last, since Essingeleden highway is a very strong and central network, parts of the infrastructure will remain and will accommodate a new public transportation route to replace the highway network.

abstract: Measurements of the geometrical magnetoresistance of a conventional semiconductor, gallium arsenide (GaAs), and a more recently developed semiconductor, iron pyrite (FeS2) were measured in the Corbino disc geometry as a function of magnetic field to determine the carrier mobility (μm). These results were compared with measurements of the Hall mobility (μH) made in the Van der Pauw configuration. The scattering coefficient (ξ), defined as the ratio between magnetoresistance and Hall mobility (μm/μH), was determined experimentally for GaAs and natural pyrite from 300 K to 4.2 K. The effect of contact resistance and heating on the measurement accuracy is discussed. / Dissertation/Thesis / Masters Thesis Materials Science and Engineering 2016
