Trafikklasser för markplattor av natursten : förslag till klassificeringstabell
This report deals with hard surfaces and the factors which are behind the criteria for dimensioning, also dependent on the level, or volume, of traffic. A test was made on slabs of two kinds of natural stone. This was made to see if the values that were reached for breakload was transferable to the same tables that the concrete industry is using for surface dimensions of slabs and paving stones. The test showed very high values and the result, together with the written study, led to the author?s suggestion for a classification table where slabs of natural stone were divided in to different classes depending on traffic, thickness and durability..
Kan man minska bilåkandet i staden? : sett ur ett stadsplanerarperspektiv
The reason why this essay is written can be parted in two, whereas one would be the global trend of urbanization that occurs to this moment and forward, whereas the other would be the debate of how motorism has come to be an issue of sustainable management of our cities and our environment. In purpose to deliver a thorough understanding of how the car and its capacity has come to shape the society of today, and to emphasize the problems it´s brought, a historical survey has been made, followed by the report of problems to the society formed by the needs of the car, discussed in several environmental issues, such as jamming, noise and air pollution. This is followed by the discussion of potential solutions for how city planning could return to the focus of the human scale and perspective, in purpose to correspond with the issue of ways to decrease the car use in towns. In conclusion, the given solutions are discussed, where examples like shared space, investment in public transport, mobility management and the theory of the assembled city are included, with aid from literature, to finally conclude the essay with personal thoughts of how the planning of today, or the given solutions, really are the result of sustainability for city planning from a human perspective.
ITS under byggtid - utvärdering med dynameq : Fallstudie: Intunnling av E4/E20 Tomteboda - Haga södra
Essingeleden in Stockholm is the most heavily congested road segment in Scandinavia and it is ofgreat importance for as well traffic within the city as for transit traffic. The capacity of Essingeledenand Norra Länken is not enough to accommodate all traffic. At times it is not moving at all, whichresults in long queues and an augmented risk of accidents. Consequently measures for increasing thecapacity on E4/E20, which will reduce congestion and the risk of accidents, are implemented byTrafikverket. In fall 2012 one lane of three at Pampas will be closed and so will the exit fromEssingeleden to Norra Stationsgatan, called Parkeringsbron.
Aktivering av trafiksäkerhetskameror : En studie av kameraaktiveringens effekter på fordonshastigheter i Sverige
During 2006 an estimated number of 150 persons are supposed to have been killed in road accidents caused by speed limit violations. Through Automatic traffic security control (ATK) the Swedish road administration (Vägverket) is working towards lowering the number of speed related accidents. By placing the speed cameras on roads they've managed to lower the average speed at those places. The enlargement of the number of speed cameras is based upon knowledge about for example how high the risk is for speed related accidents on the roads. The speed cameras always measure the speed in which every vehicle passes, but aren't constantly activated to register speed violations.
Ljud i landskapsarkitektur : från buller till kvalitet
Landscape architects has many ways of transforming our cities and landscapes. Traditionally, most attention has been put to visual qualities. Pen and paper are well established as the way to present proposals and to analyse in the landscape architects profession and training.
But are we perhaps missing out on other ways of seeing the landscape?
The purpose of this paper is to present sound as a tool of transformation. Sound in public spaces has long been treated just as noise and therefore unwanted.
OMBYGGNAD AV TRAFIKPLATS : Ekhagsmotet i Jönköping
We have the tradition in Sweden to build villas and houses with a wooden framework. It has become natural for us because we have so much forest in our country. Building with wood has advantages, it is easy to process, but also disadvantages, as it is sensitive to moisture.Finland has long made use of the thermal blocks to build villas. It is a type of bricks that are a bit like a sandwich element, with a core of EPS and concrete on both sides of the core material. The concrete is hollow, so that after the walls has been bricked up you pour concrete into the hollow bricks.The issue of this report is to find out if concrete can be an alternative to wood as framework material in villas.
Färdvägsmiljöer vid cykling för transport : En studie av en modell om uppfattningar av färdvägsmiljön hos cyklister
SummaryAimThe study examines a theoretical model developed to capture cyclist´s perceptions of the route environment. The survey focuses on if level two and three in the theoretical model captures what it´s intended to do. More specific we ask ourselves how the three appraisals (unsafe/safe by traffic reasons, stimulating/inhibiting route environment, unsafe/safe by other reasons) in the model´s second level relates among themselves and if these three appraisals can capture the degree of environmental well-being/unwell-being in the model´s third level. The questions were: Do the three appraisals differ among themselves? What is the difference/-s in such cases? And, is there a correlation between any of the three appraisals and environmental unwell-being/well-being? What is the correlation in such case? MethodThe gathering of data was done through questionnaires.

Cirkulationsplatsers inverkan på vägtrafikbuller
I dagens samhälle är runt två miljoner svenskar störda av trafikbuller, samtidigt som bilismen och vägtransporterna ökar. För att få en säkrare trafikmiljö med ett jämnare körsätt är det populärt att bygga om vanliga korsningar till cirkulationsplatser.Denna rapport fokuserar på vad som händer med bullernivåerna då trafiken passerar en cirkulationsplats. Undersökningarna har genomförts genom att beräknade bullernivåer jämförts med uppmätta värden från olika cirkulationsplatser. Arbetet inleds med en litteraturstudie om ljud- och bullerfrågor.Bullermätningar utfördes vid totalt åtta olika cirkulationsplatser, där både ekvivalentnivåer och maxvärden samlades in. Därefter beräknades medelvärden av dessa.
Barnröstens förändring under dagen i en anpassad röstinspelning och spontantal : En experimentell studie av perceptuella och akustiska parametrar
A controlled recording in a studio is the basis of all voice treatment. However, this controlled way of recording voice patients' voices can be questioned. The voice use may be different in a natural environment. In children noise related voice problems are investigated in a study about voice and its development (BUG ? Child voice and noise).
Samhällsekonomisk analys av ett djupförvar för använt kärnbränsle i Forsmark :
This thesis investigates the socio- and environmental economic effects of a deep repository for spent nuclear fuel in Forsmark in the municipality of Östhammar. I seek to show the general picture but focus on the effects on employment, environment and income. Cost-benefit analysis is used to investigate the differences in utility between a scenario with and a scenario without a deep repository in Forsmark.
Most of the possible effects can not be valued and many can not even be quantified with the data available today. Therefore this thesis has a bit of a ?preliminary study character? and seeks to show what we know today and what needs to be further investigated when available data allow it.
The costs that could be valued are noise from the traffic during the period of building and emissions of carbon dioxide and nitrogen oxides from the transportation of rock masses during the building period.
Att genom design effektivisera räddningsinsatsen för motorcyklister i trafikolycka
What if the emergency response directly knew exactly where to go and what to do if a road accident occured? During the last ten years the number of motorcyclists in Sweden has doubled. Every year, more than 300 riders are seriously injured and over 40 die in road accidents. Being found in time is critical to increase the chance of survival. The goal of this project is to use design methods to find a solution that enables a fast and adequate emergency response for motorcyclists and other unprotected road users..
Solel från ljudbarriär : längs Annetorpsvägen i Hyllie, Malmö
City of Malmö has ambitions for the district Hyllie to become a demonstrative area ofsustainable urban development. As a part of this the following report aims to investigate the potential in using noise barriers combined with photovoltaics along Annetorpsvägen to generate solar electricity. To quantify the losses that shadows from buildings along the roadmight cause, a 3D-model of the area was constructed in SketchUp. This digital model made it possible to simulate shadows and how they change over the year. A reference model of a photovoltaic noise barrier (PVNB) was constructed and used to find the dates on which the solar cells are shadowed depending on building heights and positioning of the barrier.The results show that two lengths with a total distance of 400 meters is appropriate for applying photovoltaic noise barriers.
Nya Slussen i dagspressen : En kvantitativ innehållsanalys och kritisk diskursanalys av Dagens Nyheters, Svenska Dagbladets, Expressens och Aftonbladets rapportering om Nya Slussen
The reconstruction of a central area in Stockholm named Slussen (The sluice) has frequently been portrayed and debated in media over the last few years, escalating around December 2011 when the major decision regarding Slussen was to be made by the city council. The area serves as a traffic node connecting the areas of Södermalm and Gamla Stan (Old town) together. The last major change of Slussen was completed in 1935, best described as a modernistic traffic and architectural piece of work. It is indisputably an area of importance for the city of Stockholm, its citizens and visitors. How has media reported the development of the New Slussen project?The analysis, and the conclusions drawn from it, will be based upon and performed with a quantitative content analysis and critical discourse analysis.
Administrativt Trafikskoleverktyg
This examination project is carried out for Waséns Traffic School in Linköping. The task was to develop a completely new windows application and a webpage that connects to the same MySQL database. The windows application (ATSV) is a program intended to carry out all the administrative tasks that a clerk at a traffic school may need: pupil management, reservations, billing and register functions. The applications was developed in C++ using Visual C++ from Microsoft. The connection to the MySQL database was made possible by using the class package MySQL++.
