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.

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.

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.

This paper was part of the ongoing cooperation between the Swedish Civil Aviation Authority and the Department of Psychology at Lund University. The purpose of this study was to develop a self-report measure regarding human factors, for the Air traffic controllers to fill out before they start their working shift. This in order to aid the team leaders in their judgment regarding the Air traffic controller's ability to perform at the right safety level. The self-report measure would also serve as an aid for the Air traffic controllers who have a responsibility regarding their own performance. If successful this self-report measure would make it easier for the Air traffic controllers to be alert regarding certain factors that can have a large impact on their performance.

This study focuses on the integrity of students at Uppsala University that has used the university?s network, UpUnet. We?ve studied their opinions with the use of questionnaires that cover questions related to privacy and awareness about logging of data traffic.The results showed that more students than our hypothesis suggested were unaware of the surveillance on the network, and the majority of these also had a negative opinion towards logging of data traffic. However, we found that there were several relations between how the students responded on our questionnaire, and we?ve presented these in the analysis chapter towards the end of the essay..

Self-driving cars are soon to become a reality to the commercial market. A self-driving car does not have a human operator, which enables some interesting characteristics. The main benefits are considered to be:The number of accidents and traffic jams should be reduced.Enhanced comfort.Energy usage could be decreased while capacity could be increased.This study concerns the causes for improved energy efficiency. The reason for improved energy efficiency is mainly because of the variation in terms of acceleration, braking and distance holding are reduced. The vehicles are more intelligent and can work together as a unity.

In motion ?a traffic program for Nacka is the result of a survey of the traffic system and transportation situation in Nacka and suggests possible development opportunities. A new traffic strategy will be developed in the municipality of Nacka the coming years, which is the reason for this study: to map the current situation, identify strengths and weaknesses, needs and opportunities. This program suggests possible development opportunities and gives an historical overview of the transportation system, the current situation and an analysis of different transportation modes. A mapping of other municipalities? traffic strategies or programs have been done and included into the program as well as a prognosis for the coming years in the municipality.

The farm management system controlled traffic farming (CTF) aims to reduce soil compaction by restricting the field traffic from agricultural machinery to permanent traffic lanes. Literature and empirical findings show that soil compaction and field traffic from heavy machinery may affect crop growth negatively, reducing crop yields. If grass-clover leys are subject to heavy field traffic the botanic composition might be altered, providing a lower clover content in the forage. Clover as a silage feed is rich in protein providing good conditions for high yielding dairy cows. Grass-clover silage production is generally associated with intensive field traffic.

In industrial control systems PID-control remains the prevalent strategy, also for processes that would benefit from model based control. The purpose of this thesis is to evaluate whether model based control can be readily implemented in an industrial control system. To this end a simulated surge tank with a simulated industrial control system is studied. For evaluation two scenarios with specified objectives are selected.Following a review of LQR and versions of MPC, Predictive Functional Control (PFC) is considered the most suitable for implementation. PFC is a form of MPC developed with industrial applications in mind and therefore has several advantages for implementation in an industrial control system.

Firewalls protect network traffic and decide witch traffic to send further and witch traffic will be blocked. All this depends on the rules in the firewall. The firewall is installed between the internal network and the Internet. It is difficult to find a firewall that can protect us against different threats. Firewalls have both advantages and disadvantages and all this make them vulnerable.
