When traffic in large cities increases, it becomes more vulnerable to disturbances such as accidents, stalled vehicles or construction; therefore, traffic jams are more likely to occur. For better control of the traffic at a disturbance the Swedish National Road Administration (SNRA) has traffic equipment which can be controlled from a command centre. This traffic equipment consists of gates and signs with variable messages. This report will discuss the system used for traffic control in Stockholm. It will present proposals designed to improve it.

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.

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.

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.

This thesis consists of four case studies. The objective is to find out how to get a well functioning Cow traffic in an automatic milking system. Different technical and building solutions are analysed and some adjustments are proposed for the DeLaval herd management software. Case study 1: Lactation chart comparison from traditional Cow traffic and Feed First? Cow traffic Case study 2: Farm A - a study of the precedence passage and the Cow traffic Case study 3: Farm B ? an overview of the farm and their way of working Case study 4: Key factors ? how can we judge how well a VMS farm is working? Case study 1: Lactation chart comparison from traditional Cow traffic and Feed First? Cow traffic In this survey data is analysed from before and after rebuilding to Feed First? Cow traffic. Lactation graphs are compared between traditional Cow traffic and Feed First? Cow traffic.

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.

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.

Researchers, planners, and government agencies agree that road safety for children must be a priority and in particular that children should have a safe and secure way to travel to and from school regardless of age or the distance travelled. In Sweden, child traffic safety is a key part of the country?s Nollvision, a long-term traffic policy goal of ?no deaths or serious injuries?. Unfortunately, many countries have recorded increases in child traffic accidents as the percentage of parents who drive their children to school and thus congestion around schools has increased. Common strategies include traffic safety education for children, the redesign and improvement of traffic infrastructure, bicycle training, and carpooling.This thesis assesses the traffic problem around Ludvigsberg School in the district Valbo in Gävle, Sweden.

Several cities have implemented various projects to improve traffic safety in city centers.During 1970s and 1980s the city centers changed as the suburbs grew and large shopping centers were located outside the center. At the same time, several projects were initiated with construction of pedestrian streets and restriction of traffic in the center. In year 1994,shared-used areas were introduced in Sweden and these areas are often used in center environments.In Sweden, municipalities are responsible for integrating security in public places and in comprehensive plans and detailed development plans. The National Board of Housing,Building and Planning is the authority for administrating planning issues and develop general guidance about planning. Traffic is one of their key issues, although today there are no concrete guidelines from the National Board of Housing, Building and Planningfor the design of traffic safety in city centers.Traffic safety in city centers affects many people because the city center is a public place.It is therefore important that there are current guidelines available that are helpful for changes and improvements in traffic safety in the city center.The purpose of this report is to formulate guidelines for planning city centers from a traffic safety perspective.

In this thesis, it is investigated if it is possible to create a common factor of the work tasks done by an air traffic controller, which then can measure workload. This will lead to the development of a tool to measure workload at small airports. In the research project a questionnaire is created to measure the different tasks an air traffic controller has. The same questionnaire will also measure the number of environmental factors that exists around the air traffic controller. To measure the validity of the questionnaire, the authors are using NASA-TLX.

The aim of this study is to examine which factors in a traffic wardens? situation at work that promote and which that inhibit satisfaction at work. The aim of this study is also to examine if there are any differences in the work experiences for traffic wardens that work alone versus those who work in a team of two. The following questions are examined in the study:?Which factors promote and which factors inhibit the work situation for traffic wardens??Are there any differences between traffic wardens that work alone and those who work with another colleague?The selection consisted of eight traffic wardens, of which four of them work with another colleague while the other four work by themselves.
