I am Boris Yotsov and I 'm from Bulgaria. The title of my master thesis is: "Pedestrian Traffic in Sofia." I determine the current situation of pedestrian traffic in Sofia, define the problem of pedestrian traffic, provide an improvement action plan, and make a comparison between pedestrian traffic in Sofia and Vienna. The master thesis consists of two major parts, a theoretical part and an investigation. The theoretical part represents general parameters of the pedestrian traffic, including a comparison between Austrian and Bulgarian policies and regulations. The investigation deals with the determination of the current situation of pedestrian infrastructure in Sofia and definition of the problem. Here I determine also the walking speed of people in various locations in Vienna and Sofia. In the second part of the study, the observation is performed by an inquiry. In addition to a hypothetical behavior, inquired in different situations, theoretical behavior of pedestrians will be considered. In addition, I try to have a meeting with people from the local and regional government to obtain information about existing projects for improvement of the pedestrian traffic in Sofia. Finally I suggest a new transport strategy for pedestrian traffic and possible procedures for making it more attractive in political level. My goal is all city traffic planners and politicians to be inspired and see the world with other eyes. Sofia has central role in Bulgaria. The population in Sofia is increased each year with an accelerated pace. Sofia is a candidate for "European City of Culture" for 2019. There is need of many improvements not only connected with culture, but also with pedestrian infrastructure. The well-planned and designed Infrastructure is a sign of quality of life. The main results are summarized from many documents, lines and prescriptions of design, my own analysis and surveys of foot passengers in Sofia. I have obtained the transport master plan of Sofia for pedestrian traffic. The investigation has shown that the average pedestrian speed in Vienna is higher with 0,12 m/s than in Sofia. The group of disabled people and the group of small children, old people in Vienna have shown a very higher speed than those in Sofia. The reasons are: the better condition of the pedestrian infrastructure, particularly the sidewalk coverings, the earlier time of the calculation of the velocities and also the disabled friendly design of the pedestrian network in Vienna. The Viennese women and men go with 0,1 m/s faster than those in Sofia. The reason is that a free time traffic predominates in Sofia. In the survey, I learned that the pedestrians are not satisfied with the current state of pedestrian infrastructure, especially with its multiple defects, which are also present in other European cities. The pedestrians feel insecure and threatened by cars. I have examined five sections of the pedestrian infrastructure in Sofia. I have defined the problems. For each defect I have considered detailed proposals for its removal. The evaluation of the results of the investigation has shown many problems, associated with poor condition of the sidewalk coverings, narrow sidewalks, lack of crossing facilities and etc.
