Based on the research of existing literature, examples of good practices from abroad and consideration of cases from national practice, the research project will look for ways to include mobility plans for new developments in spatial and transport planning procedures. Within the framework of the project, the responsibilities of the state and municipalities in this area will be defined, the need for changes and additions to existing legislation and the strengthening of knowledge will be identified, with which all key stakeholders will be able to effectively participate in the preparation of these plans. The expected results of the project will provide an insight into the possibilities and directions for the development of this important tool, with which we want to ensure a better integration of spatial and traffic planning at the national level.
