Hastighetsreduktion på genomfartsleder, genom icke-tvingande åtgärder i vägmiljön
The study was conducted with an landscape approach with an subject related approach in the field of environmental psychology to investigate how road design affects drivers' choice of speed. The purpose was to portray road environments on thoroughfares in urban areas to motivate motorists to keep the speed limit and thus increase road safety for vulnerable Road users. The task question was formulated, how can thoroughfares in suburban settings be portrayed to motivate motorists to reduce speed?
The study was conducted throughout a literature review of motivational speed measures along with interviews with road design experts at the Swedish Transport Administration. Case studies were conducted on three thoroughfares in the Stockholm suburbs Vallentuna, Upplands Väsby and Danderyd.

The question is being discussed in interviews with two employees at the Swedish National Road Administration and two former members of the ?Council of environment and beauty? at the Swedish National Road Administration. The interviews are summarized in my own discussion about the concept of ?Beautiful roads?.
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.
Lita på mig! En studie av tillit på virtual communities
The technical achievements that have occurred in recent years have led to a greater use of the Internet around the world. Today, more and more people are using virtual communities, a place where communication occurs with people who have similar interest. Due to the option of being an anonymous user, the concept of trust plays a big part in how virtual communities are working. It is therefore of interest to investigate how trust develops between users in virtual communities. This report asks the following question:"How is trust formed between users at a virtual community?"A qualitative and netnographical study was conducted to answer the question above.
Slitage på skogsbilvägar vid virkestransporter
This report discusses questions concerning wear on forest roads. The purpose of the work is to investigate if the wear on the roads will decrease when the speed limit gets lower for the trucks that transport the wood. A normal forest road, class B, was used in the study. In total 5000 m3f timber was transported on the road. Data about the road was measured with a profilograph car before and after the timber transport.
Uppdatering av båtnadskalkyl med hänsyn till nya faktorer :
Sweden have 419 000 km road in the country and about half of these roads is forestroads. The forest road net most important mission is to make it possible to deliver wood from the forest to the industries. With a raw material that is spread over a large area the road network is important. Each year has the forest road network been extended with about 1 700 km new roads. To decide if a new road is to be built different forest road cost estimation models has been used.
Tillit inom illegal e-handel. En fallstudie av marknadsplatsen Silk Road
Since the beginning of the internet the criminal world has used the medium as a platform for operation.This dark web is a domain where illegal sites are flourishing due to the possibilities offered by newtechnology. Net-based criminal activity is a challenge for society as it uses hard proof technologicalsafety measures to avoid the law. Silk Road is the most prominent example, an online illicitmarketplace where drugs and illegal substances are being traded based on conventional e-commerceconcepts. This paper argues for trust as an important factor for the survival of illicit online trade andapplies existing theories on e-commerce and virtual communities. To identify patterns of trust andcommon trust-based issues among Silk Road users, a netnographic study was conducted on the site?sdiscussion forum.
Utformning av vägen och dess omgivning : med fokus på bilförarens upplevelser
This thesis focuses on the driver?s experience of the road and its surroundings. ?The view from the road? takes place every day and a high-quality ?road experience? is therefore a question of importance. Since cars made their breakthrough in the 1920-30, the approach to ?the driver experience? has varied notably.
Wildlife Detection Network
Traffic accidents where wild animals are involved represents between 60 and 80 percent of all reported accidents, depending on location in Sweden. In a country like Sweden, with a lot of forest, there is always risk of a collision with a wild animal. Imagine if you, as a Road user, had the possibility to receive warnings when the risk of an accident according to statistics is extra high.Wildlife Detection Network is a wildlife warning system with an information service, which makes the whole concept unique. When an animal is approaching the road, it is registered by sensors, and warning lights along the road are lit to inform drivers of the potential danger. In conclusion, this is a direct warning to all drivers on the road where the system is placed.When an animal is registered by the sensors, information containing time, date, weather circumstances and coordinates are sent to a database.
Förebyggande Brounderhåll
AbstractThe Swedish Road Administration in the region of Mälardalen has since 2004 worked to in¬crease the efficiency of the maintance of bridges based on limited functional requirements and time demanded action.The maintenance of the bridges is contracted in the county of Uppsala since 2004, and Örebro since 2007. The county of Nyköping and Västerås is contracted by the traditional system. The contractor will perform a regular maintenance on all bridges. The bridges are inspected by the contractor at least once every year.The contractor registers the result of the inspection in a database called BaTMan. BaTMan is a Bridge and Tunnel Management system and is a strictly web solution were the user logs in via the internet.The Swedish Road Administration also inspects the bridges to se that the demands on the bridges are followed.My work is to compare these different inspections and to see any development..
Gabioner - Ett alternativ vid vägbanksbygge i lösa leror
The use of gabions means a reduced amount of filling material in the road section and a more narrow construction. Also the use of limestone cement columns can be reduced. All together this results in lower costs. The columns stand for about 55% of the total costs for the road. If gabions are used you can reduce the total costs with over 10%..
Metod för användning av Geografiska Informations System vid långsiktig vägplanering : en studie genomförd på Sveaskogs marker i Norrbotten
The forest industry is one of the most important industry branches in Sweden. Since the demand of high precision wood deliveries has increased, the demand on a well constructed forest road net also has increased. A good road net gives the wood-supplier competition advantages and also increases its service level towards its customers, lumber-mills and pulp-mills. In some parts of Norrbotten, the road net is still insufficient and not yet built out enough, and that is why it is important to know how to act and where to improve the road net in these areas.
The purpose of this thesis was to create a work-model for long term road planning in areas with no road net or a not yet complete road net. The model has been created in an ArcGis environment, where a long chain of tools has been tied together with the program ?Model builder?.
Ny metod fo?r ma?tning av va?gkvalitet : En statistisk studie o?ver samband mellan va?gkvalitet och socioekonomisk utveckling
New method for measuring road quality- A statisticalstudy of the relationship between road quality andsocioeconomic development A new tool with implications for road maintenance has the potential to yield statistical data for road quality in a large number of regions. This thesis investigates the possibility to develop a method, from this data, for evaluating the effects of road quality on socioeconomic development.The thesis is essentially divided into two parts. Part one looks to qualitatively establish the link between socioeconomic development and road quality and the second part focuses on how to develop a method for evaluating the effects of road quality on socioeconomic development. A method was devised using categorical data and a multinomial regression model. This method provides a comprehensive overview of the complex relationship between a variety of different variables.
Effekter av "Billigaste väg" för Stora Enso Skogs transportverksamhet :
Transportation constitutes a large part of the forest industry's raw material costs. Transport also contributes a significant proportion of the carbon dioxide emissions. In order to reduce both the cost and environmental impact different types of decision support are required. These, in turn, require extensive information about the road network and correct information on road path selection and transport distances. In the development of national road data base for forestry (SNVDB) a road selection application has been included.
Vägprojekt: nya E4:an, delsträckan mellan Uppsala och Läby : Så gick besluts- och samrådsprocessen till
A Road project?s frame is built up of a decision- and consultation process, where the results of the preparatory studies are being discussed. The aim with a consultation process is that all theopinions and knowledge from the operators' will be taken into count in the basis of information, that is needed in order to the different involved operators' to take a decision.The aim of the essay was to investigate how the decision- and consultation process for a road project, the E4 section between Uppsala Läby, turned out. The aim is also to bring up how theprocess could have been done more correctly. The study was carried out through a qualitative method with an analysis of materials from the National Road Administration's archives, the associated Environmental Impact Assessment (EIA) and through interviews of the different operators.My theoretical basis has been a Stakeholder Analysis and its principles, and theory about different executions of social planning.The result showed that the decision- and consultation process has been bursting in democracy and consideration taking of the different operators' opinions, has been poor from the developer?s, in this case the National Road Administration's, side.
