Vägparametrar och deras inverkan på trafiksäkerheten : Fallstudie på länsväg 360 Lycksele - Vilhelmina
The interaction between the driver, the car and the road is essential for the road safety. This case study focuses on the road condition and its effect regarding road safety issues. By studying and isolating the road condition aspect and its contributing role to the accident occurrence, the aim is to explore their relationship, as well as highlight the road parameters that are commonly associated with accident occurrence. This result will be used to develop and increase awareness of the impact of poor road alignment and poor road surface conditions on traffic safety, in order to prevent these accidents from occurring. The road parameters chosen for this study include side friction, cross slope and rut bottom cross slope, road texture, curvature, drainage gradient and rutting.The case study was limited to lv 360 in Va?sterbotten, where all accidents with an unclear cause of the accident were studied, between 2003 and 2012 were carefully studied and assessed based on the condition of the road at the time of the accident.
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.
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..
Utvärdering av Skvallertorget i Norrköping
This thesis is an evaluation of the new traffic solution at ?Skvallertorget?. The innovative theory behind it is to increase traffic-safety by introducing insecurity feelings for road-users. The conclusion of the evaluation is that the newtraffic solution is well adjusted according to guidelines for municipal traffic planning. The evaluation also illustrates the conflict between traffic planners deliberate attempt to avoid clear information and the road users wish to get it.
Effect of cow traffic system on cow performance and AMS capacity
Robotic milking in Automatic Milking systems (AMS) is proposed to reduce manual labour and at the same time increase milk yield by increasing milking frequency. In order to increase milking frequency, it is essential to have well-functioning cow traffic. Investing in an AMS is a great capital investment for the farmer, thus it is of major importance to ensure maximal AMS capacity. This study investigated the effect of the traffic systems Feed First? and Free cow traffic with and without waiting area (WA) on cow performance and AMS capacity.
Analytisk dimensionering av räddningstjänsten i Skåne Nordväst
This report is a part of the process of enhanced cooperation between fire rescue services in the region of North West Scania. The aim of the report is to study and analyze how the fire rescue service should be structured, in terms of rescue units and personnel, if no account is to be taking to the current organization. Two types of accident are considered in the report, Traffic accidents and building fires. These are more affected by decreased response time than other accidents. Several suggested organizations are presented and they are evaluated with the computer program REP.
Energieffektiv Linjesjöfart Till Och Från Gotland
The ferry traffic to Gotland is essential for the island?s ability to live and develop. Yearly, it transports 1,6 million passengers, 500 000 personal vehicles and 750 000 lane meters of freight with four Ro-Pax ferries. The traffic is controlled and subsidized by the Swedish government since 1971 in order to guarantee the inhabitants and industry of Gotland a satisfactory transportation service. As a consequence of the past decades increased traffic quality, mainly due to a decrease in crossing times, the traffic?s environmental impact and costs has also increased.The Master Thesis proposes a new energy efficient traffic arrangement that satisfies the users? preferences in the same extent as today.
Risks Related to the Maritime Transportation of Oil and Gas (mainly Crude oil, LPG, and LNG) -A Conceptual Study and Empirical Outlook on the Baltic Sea and UK Territorial Waters to Mitigate Risks
Transportation of oil and gas by the Sea characterizes challenges from a safety viewpoint. In this type of transportation, different sizes of special tankers carrying oil and gas. The marine transportation of these scarce natural riches is involved with risks and hazards, which may lead to many losses; for instance, wasting oil and gas, injuries of people, damaging ships and properties, and damaging environment. The main purpose of this thesis is to evaluate the risks, hazards, and accidents during transportation of oil and gas (mainly Crude Oil, liquefied petroleum gas, and Liquefied natural gas) by the Sea with concentrating on transport safety. Hence, a better understanding of these risks and hazards can contribute to decrease of addressed losses.This study is carried out on risks associated with maritime transportation of oil and gas starting with describing the general casual chain (dealing with causes, incidents, accidents and consequences/causalities), continuing with describing risk analysis techniques (including event tree analysis and fault tree analysis) and risk control measures/options, and finally implementing aforesaid investigations on real data from two areas; namely UK territorial waters and the Baltic Sea.In this study, the results of analyzing data from 1991 to 2010 in UK territorial waters revealed that collision and grounding were two most common accidents in terms of crude oil tankers, LPG and LNG carriers in which 44% of all accidents were equally divided between collision and grounding.
Renar och klövvilt på järnvägar : en studie i järnvägars effekter på ren, älg och rådjur i norra och mellersta Sverige under 2005
Roads and railroads have significant impact on the surrounding landscape and the wildlife living in it. This study aims to provide an overview of the effects caused by railways to reindeer, roe deer and moose in Sweden in order to make more detailed assessments within this topic in the future. The method used is a study of literature on the subject and a synthesis of databases with information about wildlife mortalities, traffic intensity and fences in the study area; northern and central Sweden. The databases were used to compile digital maps using ArcGIS.
Infrastructure brings change to the surrounding landscape and its function as habitat for wildlife. Railroads cause barrier effects such as fragmentation, wildlife mortality, loss of habitat and loss of connectivity.

Trafikinformation som når ut : En studie om nya kanaler för störningsinformation i trafiken
The Swedish traffic system is congested, especially in the urban areas; travellers face daily growing traffic jams and delays in public transport. In a congested traffic system, travellers need support to make smart and sustainable decisions and one such tool is traffic information.One issue today is that too few travellers use traffic information in support of their travel. Research shows that travellers would see great value in receiving the information; however current systems do not meet their requirements. This is a problem since the society would benefit greatly from a well functioning traffic information system.In this report, a number of channels that can be applicable for providing traffic information will be explored, with particular emphasis on interference information.The information channels are analyzed based upon the needs and requirements of the society and the traveller. The thesis of the report is: the more of these needs and requirements are met in a channel; the better is the channel to use for traffic information.

ABSTRACT This essay is about traffic analysis of Web servers. The purpose is to investigate if companies analyse the traffic on the Web server and if they use this information to create more than simple statistic reports. The questions that we will answer are the following: ? How common is traffic analysis on the Web server among companies? ? Is the Web administrator limited in analysing the Web traffic, if the company has the website on a Web hotel? ? Does the company uses the results they get from analysing the traffic on the Web server for updates and changes on the Web page? To answer these questions we made a questionnaire investigation by telephone interviewing the companies? webmasters. The extent of the investigation was 20 companies in Blekinge.
Whiplash : Preskription och adekvat kausalitet vid trafikolyckor
Whiplash is a bodily injury, where the person that is injured is subjected to force towards the neck, mainly in Traffic accidents. Even low speed accidents can cause severe damage due to the complicated muscle and nerve structure of the neck. Symptoms range from neck aches and headaches to numb fingers and this makes the Whiplash injury difficult to diagnose. Whiplash is also a treacherous injury due to the fact that the symptoms can not be objectively verified. The principal symptom of the injury is pain, which is to its nature highly subjective.

ABSTRACT
This essay is about traffic analysis of Web servers. The purpose is to
investigate if companies analyse the traffic on the Web server and if they use
this information to create more than simple statistic reports. The questions
that we will answer are the following:
? How common is traffic analysis on the Web server among companies?
? Is the Web administrator limited in analysing the Web traffic, if the company
has the website on a Web hotel?
? Does the company uses the results they get from analysing the traffic on the
Web server for updates and changes on the Web page?
To answer these questions we made a questionnaire investigation by telephone
interviewing the companies? webmasters. The extent of the investigation was 20
companies in Blekinge.
The information we gathered from the investigation showed that it is becoming
more common that companies analyse the traffic on the Web page and that they
uses the information to more than statistic reports, for example updates and
changes of the Web page.
Does tree removal along railroads in Sweden influence the risk of train accidents with moose and roe deer?
After the storm Gudrun in 2005, the Swedish Transport Administration started clear-cutting of railroad corridors to reduce the risk of trees falling down on the tracks. Simultaneously, train accidents with moose and roe deer have become more frequent and the costs for consequent delays and repairs of engines are of growing concern. There is reason to assume that tree-clearance of railroad corridors may have contributed to an increase in number of accidents with moose and roe deer because the cleared areas provide attractive forage and thus may attract wildlife. The objective of my study was to investigate how clearing of trees affected the number of accidents with moose and roe deer. I compared deer-train collision frequencies before and after clearance of the selected railroads and compared these with uncleared control railroads in a BACI (before-after control-impact) approach.
