    Hästanpassade vägar: I Leksands Kommun2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Approximately 13 000 persons get injured every year in Sweden while riding or handling a horse. Due to regulations, a horse is not allowed on to the walk- and cycle path or the sidewalks. Since some places don’t have paths developed for the horse, the equipage is forced out in trafficked roads. The horse is a prey animal, they run first and then they stop to see what the potential threat was. This, in combination with car driver´s general lack of knowledge about horses, could increase the possibility of an accident.The purpose of this project is to evaluate if the equestrian practitioners find it difficult to be in traffic environment with the horse and how commonly practitioners use public roads with the horse. The purpose is also to provide a review of how well the equestrian practitioners are aware of the traffic rules regarding horses in traffic. The main purpose of this thesis is, however, to offer suggestions on how road design should be improved with regard to road safety, security and accessibility for equestrian practitioners.

    The study was carried out with a questionnaire and studying literature. The questionnaire was handed out to 38 members of the riding club of Leksand. The results show that the knowledge of traffic rules could be increased among the ones who answered the questionnaire. They also think that the horse needs to be a part of the community and infrastructure planning and that all road-users need to learn more about horses in traffic, to better understand its behavior. Other proposals are lowered speed limits for motorized traffic at

    Korrelation mellan spårriktningsåtgärder och befästningstyp, ballastålder, rälåder samt rälvikt2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The Swedish Transport Administration has stated that the maintenance of the Swedish railway network has been neglected. To maintain adequate supply of transport in the long term preventative measures are required. The purpose of this thesis is to analyze how fastening, ballast age, rail age and rail weight influence the need for tamping action on the Swedish railway network. The purpose is also to clarify if the used method is useful for further analysis on the topic.

    The work was based on the Swedish Transport Administrations infrastructure data from the years 2007-2013 consisting of information about tamping, fastening, rail, ballast, freight traffic, passenger traffic, tonnage and traffic volume. A selection was carried out to simplify the study and then Excel was used to correlate data. Analysis about fastening was conducted per track meter, while the analysis for the rail and ballast was conducted per line section.

    An analysis, weighted for the volume of traffic in terms of gross tonnage and number of trains show that the type of fastening that requires the most tamping actions is Rail Spike while the fastening that is currently used for new construction, Pandrol Fastclip, is one type that requires few tamping actions. The median age for tamping actions was 22 years regarding both ballast and rail. The rail mean weight that requires the most tamping actions is according to the results 50 kg/m, which is also the most common rail weight.

    The method used in this thesis provides a good foundation for further study but should be evaluated and developed for use in preparation of economic effect models of maintenance for the Swedish railway network.

    Evaluating thermal comfort in a Swedish block of flats: A methodological comparison2017Conference paper (Refereed)
    Abstract [en]

    Two methodological approaches have been used to investigate thermal comfort amongoccupants in a Swedish block of flats; measurements and thermal comfort standards on the onehand, and qualitative interviews on the other. The purpose with this paper is to present, compareand discuss results from these two radically different methods. The results coincide concerningvariations of thermal comfort throughout the day, but are much less in accord in results whereoccupants express, or are presumed to complain of, thermal discomfort. The interviews showthat female occupants tend to suffer more from thermal discomfort than male occupants, a resultwhich is absent in the measurement methodology. The results give support to suggestions thatgender aspects should be taken more into account when determining and controlling thermalcomfort. The differing results also point at the importance of complementing standardizedthermal comfort measurements with surveys or qualitative interviews.
