The master's thesis explores the transformation of urban public space by using the sustainable urban transport planning on the subject of open public spaces in the wider centre of Ljubljana. Under the term »transformation« we imply the connection between spatial management of open public space in the town and the scope of sustainable mobility, because our opinion is that a well-managed open public space is to be transformed, i.e. its usage and its use of sustainable ways of mobility. This implies that non-motorised ways of mobility are used more often as well as people spending time in public space more often. The master's thesis comprises of two parts. We dealt with the first part theoretically, we also presented the significance of open public space for the city in depth. We dealt with another variable theoretically, namely with the sustainable mobility and their mutual interconnection. The second part of the thesis contains the analysis of spatial and traffic management of the chosen open public spaces in Ljubljana. With the help of literature we chose indicators for determining the spatial management of open public spaces. That was the base to determine the criteria for grading the spatial management of open public spaces (a non-managed, medium-managed, well-managed space). We chose the cases of well-managed and medium-managed open public spaces in Ljubljana. The questionnaire-based aim of the research, whose database consisted of possible users of such public spaces was to find out the scope and scope-change of sustainable mobility in Ljubljana, related to users' evaluation of spatial management of open public space and also related to the significance of spatial management of open public space for the users.
With the view that the well-managed open public space in the city encourages the use of sustainable non-motorised ways of mobility and regular usage of open public space, we set out three hypotheses, whose validity we checked with statistical tests ANOVA and the Kullback test for connectedness. The first two hypotheses were concerned with dependency on frequency of chosing non-motorised ways of mobility, i.e. on the spatial management of open public space and on users' grading of spatial management of open public space. The statistical test ANOVA proved the two hypotheses partly. The third hypothesis was concerned with users' contentment of open public spaces in relation to the car-traffic closure for the city centre of Ljubljana (as one of the spatial management activities for open public space), and the closure's impact on users visiting the city centre. The Kullback test entirely confirmed the hypothesis for connectedness.
