Sustainable mobility means keeping the ability of people to travel and supply goods in a way that balances environmental and socio-economic aspects and aims at the reducing of negative impacts on environment. The aim of this research is to study how the mobility governance is built and particularly governed in sustainability understanding aspects in urban municipalities in Latvia, using the case of Valmiera town. In the scope of this step-by-step complementary study different transportation modes have been studied with special emphasis put on the necessary application of socio-ecological system and stakeholder participation principles, and, particularly, governance instruments design and application -all six main groups of instruments and their complementary application for urban sustainable mobility. The research has been carried out employing both research-and-development framework and case study research methods, allowing to provide integrative contextual analysis of the particular sustainable mobility subject in the chosen urban area, including document analysis, semi-structured deep interviews with each stakeholder group representatives, household proenvironmental behaviour questionnaire and structured observations. Also, the development planning process was studied and in particular the case of Valmiera Transport development program development and its impact on environment assessment. The research allowed drawing conclusions on the urban sustainable mobility governance aspects in Valmiera and for Latvia municipalities in general. The future developments should include the joint action plan that would foresee the cooperation and implementation of integrative action between the different transport sectors, policy makers, and relevant authorities, as well as sectorial and inter-sectorial policies planning. These documents should be based not only on detailed and professional evaluation of the transportation aspects in the municipality, but to be based on social-ecological systems governance understanding and application, subsequently, including also on evaluation and modelling of transport related environmental issues such as air pollution and environmental noise etc. in order to manage basic challenge for sector-based planning system and special integration of transport planning and environmental planning.
