The main purpose with the project has been to approximate the magnitude of the pollution transport from the actual road surfaces and to get an approximation of the possibility to collect the pollutants to reduce the load to the water and improve the water quality.The quantity of pollution transport from the most trafficated roads areas in Örebro city has been calculated. Roads whith a traffic exceeding 10 000 vehicle/day. The study has been done with the calculation tool StormTac. Through analysis of traffic loads and road surface, which together with a different kinds of parameters gives an approximation of the pollutant transport.The calculation has included some metals and other substances in the stormwater and has also included the present of suspended solids. Included the overall study, some smaller areas has also been calculated for the possibility to remove pollutants.The work also includes calculation for three different areas for stormwater treatment.

In Sweden plans to build high speed railways have been around since the early 1990s and the planshave developed to be more precised since. The future Swedish high-speed rail network is supposedto consist of two lines. Götalandsbanan; from Stockholm to Gothenburg, and Europabanan fromJönköping through the Öresund Region to Hamburg.The description of the aim to build high-speed railways in Sweden has in former reports always beento achieve rapid passenger traffic between big Scandinavian cities and Europe. There are almostnothing mentioned about the possibilities of high-speed transports of cargo on these railways. Thisstudy aims to clarify the freight transport market for Götalandsbanan and Europabanan.Today there is only one transport system with high-speed freight trains.

Well-functioning bicycle paths are relevant issues in today´s society as a way to increase active transport. Active transport means working for a better global climate, urban environment and public health. What we experience on a bicycle affects the choice of a bicycle path and is a subject where there is much left to explore. This essay examines methods in environmental psychology literature that measure the experiences of landscape. The aim is to find and apply methods to measure the experience of two bicycle paths in the Skåne plains.

With increasing traffic congestion problems in bigger cities, it is becoming more and more important to provide the traveller with correct information about all transport alternatives. When doing that, the traveller gets the opportunity to make the best decision based on the current traffic situation. Instead of traditional travel planners, where public and private transport modes are presented separately, the co-modal travel planner offers a combination. In order to make the comparison correct and fair, the travel times have to be estimated realistically and on equal basis. This master thesis focuses on how to estimate travel times in the city of Stockholm for journeys by cars, public transport, bicycles and also for walking.An investigation of the available data on maps and travel times shows where the currently used methods are lacking.

Traditional product features such as price, quality and supply service have been extended and nowadays includes environmental aspects as well. It raises new and increasing demands on haulier companies. The transport sector is responsible for a large part of the pollutants causing today?s environmental problems. The business is being closely monitored and to operate environmental friendly is seen as one of the most important elements for the industry?s future development.

The importance of good information security and safety grows larger and larger for each day in the information society of today. This concerns citizens, companies and public authorities. At the Swedish Transport Administration, the operation of an information security and safety process has evolved over the years to guarantee that the public authority can be trusted by its citizens, cooperating companies and other public authorities. This responsibility has been assigned to the Information Security and Safety Department (Informationssa?kerhetsavdelningen, ITsa?).In this thesis the aim is to review to what extent ITsa? achieves any business benefits for the Swedish Transport Administration, and to analyze, streamline and come up with solutions to improve their workflow.

The distance between home and work has increased in recent decades. By the development of infrastructure and public transport, jobs farther from home have become more accessible and this development has in turn increased commuting. Commuting travellers often pass over administrative boundaries which often serve as borders for public transport pricing. Also the market control prices. Research shows that travel times and costs significantly affect commuting choice.

Människors transportvanor skapar idag tillsammans med andra faktorer ohållbara transportsystem. Jordens befolkning använder färdmedel som förbrukar icke förnybar energi i allt större utsträckning, vilket skapar transportsystem som inte är hållbara. Dessa faktorer medför en stor miljöpåverkan på vår jord och om vi fortsätter på samma sätt som de senaste 60 åren belastas jordens kretslopp allt mer, för att slutligen upphöra att fungera.Infrastrukturen idag motsvarar de behov och krav människor har på sin transportmiljö och dessa vanor bygger till stor del på vår historiska tradition av transport. Denna historiska tradition motsvarar inte ett långsiktigt tänkande. De beteenden och levnadsvanor vi har idag påverkar kommande generationers livsmiljö, vilken kommer att äventyras om vi fortsätter på samma sätt.

Stockholm is growing with almost two fully loaded SL-buses a day. One of the consequences that derive from this is the increase of public transport travelers who put the regionally governed public transport up to the test in terms of its capacity. The Transport administration in Stockholm County initiated 2015 a project with the purpose of simplifying the calculation of bus stop capacities. A hypothesis (set up by the Transport administration) based on that a model for calculation of bus stop capacities could be calibrated for Stockholm conditions is being researched in this bachelor?s essay.The study is implemented by self-collected traffic data from bus stops located in the Stockholm city center.

All energi är viktig energi. Energin är kostsamt för växthusföretagarna i landet. I det här arbetet undersöks möjligheter att spara energi i en befintlig växthusmiljö. För att faktiskt kunna räkna på de olika besparingarna används ett fallföretag där det är möjligt att applicera de olika energibesparingarna. Arbetet fokuserar på att besvara fyra frågor angående energibesparingar i växthusmiljö. Frågorna lyder: Är det möjligt att optimera energiförbrukningen utan att försämra odlingsmöjligheterna? Var finns de största energiförlusterna hos fallföretaget? Vad finns det för kostnadsmässiga och energibesparande alternativ?, Hur mycket blir den totala energibesparingen på en helårsproduktion för de olika alternativen?. Genom en litteratursökning i ämnet hittades fem punkter hos fallföretaget som kan åtgärdas. De fem punkterna är: att isolera grunden, att isolera under bordskant, installera väv, byte av växthusportar och laga otätheter i växthuskonstruktionen. Att isolera grunden görs med hjälp av cellplast i ytterkant av anläggningen för att förhindra kall luft att komma in och varm luft att försvinna ut. Att isolera under bordskant innebär att sandwichelement placeras under bordens kant höjdmässigt för att inte försämra instrålningen av solsken.

During a fire large amounts of particles and unhealthy agents occur.  Polyaromatic hydrocarbons (PAH) and toxic metals are examples among many others. These agents have a capacity to bond to particles and when the fire is extinguished, the particles can be transferred with the extinguish water into the soil and to the groundwater.Recent studies in particles have been conducted. A study by Ulrika Iverfelt (2014) reviled that the particles from a fire contained large amounts of both PAH and metals, which is consistent with earlier analyses. Her column experiments with particles in the size ? 11 microns and ?100 microns in silica sand, reviled that the larger particles was immobilized because the transportation was influenced by sieving or physiochemical particle and surface interactions.The transport of the particles in soil and groundwater is regulated by two main mechanisms: physiochemical surface interactions and straining.

Master thesis for Mechanical engineering, at the University of Lund. Incorporated in project Pondora.The purpose of this master thesis is to compare the existing one way packaging system with a proposed return crate system not yet available in Sweden. The comparison is focused on packaging handling in the grocery store.The purpose is also to investigate how operating return crate systems in Norway and Finland function, identify, the problems they have encountered and survey economic and technical aspects. The knowledge we hereby have acquired was subjectively evaluated in the thesis.The Swedish survey has a focus on meat and bread. The surveys in Finland and Norway contain all the products utilizing the studied return crate systems.We have surveyed how the handling of transport packages for meat & provision and bread is done in the store.
