Tycho Hedéns Väg in Uppsala has evolved from being a through fare passage and highwayto the oversized road frame running through the city it is today. At the present time, dueto the relocation of the E4 highway east of Uppsala, Tycho Hedéns road creates a barrierbetween the north eastern area of Uppsala and the remaining parts of the city centre. Theroad is designed to endure heavy traffic and high speed limits, generating a surrounding urbanarea were inhabitants are complied to follow the standards set for a high traffic-accessibleenvironment. Furthermore, the heavy traffic has led to the turning of both urban roadsidesaway from the actual road. The aim of this project and proposal is to show the possibilities ofhow the innate features of Tycho Hedéns road can be used more advantageously to mend thecity area of Uppsala.

Skattning av fordonsmassa med driftstatistik

In the automatic manual transmission system, Opticruise, the choice of gear is based on several parameters such as road incline, driving resistance and vehicle mass. Many different mass estimations are made during driving. A final vehicle mass is then used to determine the current gear. Construction vehicles are often not equipped with air suspension and can therefore not estimate the vehicle mass when standing still. If that sort of vehicle is reloaded while standing still an incorrect mass estimation will be used and as an effect of that also a wrong gear.

Epiphytic lichens associated with different traffic intensities along the highway E4

Inventories of epiphytic lichens on Scots pine (Pinus sylvestris) were conducted at three sites in east central Sweden: along the newly build motorway (Road E4), along the old road (Road 600) and in a reference site, to compare the effects of traffic pollution on lichen diversities. At each site, species richness, lichen mean sensitivity value (MK), air quality index of the forest stand/sample plot (LKI) and nitrogen impact value (N) were calculated and it was tested if there was any difference between the sites. Twenty-four species were observed in total, and Parmeliopsis ambigua and Hypogymnia physodes were the most common species at all sites. At Road E4, fewer lichen species were observed than at the other sites and this might be due to the impact of air pollution. The species richness at Road 600 was similar to that of the reference site, which might be explained by the improved air quality.

Samarbete i byggprocessen : entreprenörens förväntningar på byggherren

Everywhere you look in today?s society many kinds of people are constantly interacting with each other. Especially in large groups of people working together, the phenomenon is even greater. In the construction industry there are many kinds of parts that need to come together in order to get sustainable and successful results. Therefore the relationship between the contractor and the construction client must be at its best.

Organisationskultur samt avvikelse- och förslagshantering för ständiga förbättringar i tjänsteverksamheter : Fallstudie Vägverket

Because of an increasing demand from customers and changing external environment, there is a need for continuous improvements, for both manufacturing and service organizations, to meet these demands. Manufacturing organizations have been working systematically with quality improvements for a long time, but it has not been as common for service organizations. Because of that the methods to use for implementation of the systematic improvements have not been designed to fit service organizations, and not either for public organizations. The purpose of this thesis is to explain if and why the Swedish Road Administration?s organizational culture and handling of ideas and deviation support an implementation of continuous improvement management.

GeoAnalys i Flashmiljö

There exists a great need among companies and other organizations to be able to visualize statistics. It?s also increasingly common to ask for web-based solutions for increased flexibility and accessibility for users. This paper describes how large amounts of geovisual data, for a large number of regions, can be visualized in an interactive and well-presented manner. The paper let?s you walk through two application scenarios, developed in a Flash environment, using the GeoViz component library for visualization. The first application has been developed for Statistics Sweden (SCB), to give a solution on how to visualize statistics for Sweden?s zip code regions.

Tycho Hedéns Väg : trafikrum blir stadsrum

Tycho Hedéns Väg in Uppsala has evolved from being a through fare passage and highwayto the oversized road frame running through the city it is today.

Byggdamm : Vad krävs för att minimera spridningen på ROT-projekt under produktionsskedet

Dust that arises during the construction process is called ?construction dust?.People who are exposed for construction dust for a long period of time are atrisk to develop several forms of lung problems, allergies and cancer. Todayconstruction dust is a huge problem during the production in Skanska´srenovation projects. Every day workers are exposed of the unhealthyconstruction dust and it can cause lung problems and diseases after 10-30years. This is a problem that must be taken into account to obtain a betterworking environment on Skanska´s building sites.Skanska Sweden AB has given two students the task to investigate possibleproblems about the spreading of construction dust.

Buskröjning längs skogsbilvägar : en produktivitetsstudie av två kättingslagor

To regularly remove woody vegetation along the roadside of forest roads is an important part of the road maintenance, since the vegetation binds moisture in the road side and, thus, the removal makes the road drying faster with results in improved bearing capacity. Vegetation removal also makes it easier to upgrade the road by material recycling from the ditch and, moreover, the visibility along the road is maintained.The aim of the study was to evaluate what type of chain flail is the best and most cost-effective for removal of different kind of woody vegetation along forest roadsides.Time studies were made on two chain flails when removing woody vegetation in three different classes; easy-, middle- and heavy shrub removal. The studied flails were one light and rather simple flail named Optimal M160 and a heavier and more advanced flail named Slagkraft H210. The removal was made according to Holmen Skogs? specification and the quality of the cleaning was measured by objective belt inventory.The productivity was higher with the heavy flail within all cleaning classes.

Kriminalitet sätter mannen på prov ? En studie av identitetsskapande i romanen Snabba Cash.

The aim of this Master?s thesis is to examine how representations of identity construction are performed through the characters in the novel Snabba Cash by author Jens Lapidus. I examine what means the characters are using, and how the identity construction processes are related to the idea of modern society. For a theoretical background I use sociologist Anthony Giddens? theories regarding modernity and self-identity, to study general identity construction.

Att styra bilanvändning mot en hållbar utveckling. Om geografiska livsvillkor kontra offentliga ingrepps betydelse för bilanvändning.

Car usage is determined by several facts, e.g. living conditions determined by geographical matters. There is a political will to control car usage with different kinds of incentives since car usage generates environmental problems. This essay analyses the differences between car usage in urban areas as opposed to thinly populated areas in Sweden and their significance on governmental incentives. By using statistics differences in car ownership during ten years between thinly populated areas, areas in the countryside and urban areas is studied.

L?gkonjukturens p?verkan inom byggf?retag

The purpose of this study was to gain a better understanding of how medium-sized construction companies adapt and how they choose to reorganize their operations in relation to the recession. The study has as its theoretical starting point theories about organizational learning, the impact of the economy on construction companies and strategies for dealing with recessions. The method used to conduct the study was semi-structured interviews with representatives from 15 different construction companies. The results of the study show that they used several strategies to adapt and reorganize the business in accordance with the recession. Some construction companies had to make cost savings as a result of the recession.

Vädrets påverkan på byggarbetsplatsen

This exam report contains studies about how the weather affects the construction site from a planning and productivity perspective. In 1960?s the contractors started to build during the winter, since then the demands to obtain a good construction has been higher on both the contractor and then promoter.In this report you will see how the different actors at the construction site handle the weather problems. By several interviews of the actors at the construction site there have been opinions about the weather situation which has been collected. To get a wide perspective of the problem, field studies from four different construction sites been made.Weather statistics over Halmstad is a mayor part of this report.

Värdering av anbud vid kommunala upphandlingar av byggprojekt

The thesis deals with evaluation of tenders for communal construction procurement. Each year the public procurement equals the value of millions of Swedish kronors, of which construction projects makes up a large proportion. These projects tend to often exceed their budgets. The aim with the thesis is to investigate if there are faults in the tender evaluation process. The theoretical framework for the study partly consists of a review on how the communal evaluation work is described in law and practice.

Personbilar i singelolyckor med dödlig utgång på Sveriges vägnät : Orsaker till olyckor och rekommendationer om hur dessa kan förebyggas

In Sweden the most common type of road traffic accidents involving passenger cars are single accidents (where only one vehicle is involved). The aim of this thesis is to analyse how these accidents occur, and present recommendations on how to reduce the number of deaths. Data has been collected from the Swedish Transport Administration?s in-depth studies of fatal accidents. Road traffic accidents with fatal outcome that happened on public roads during the years 2007 to 2009 have been studied.
