SUMP (Sustainable Urban Mobility Plan) is an innovative way of planning urban mobility in a sustainable manner that meets the particular needs of people. The objectives of such transportation planning are making destinations and services accessible, increasing traffic safety, reducing greenhouse gas emissions and consumption of fossil fuels, the attractiveness of urban spaces, increasing the quality of life, a healthier environment and reducing impact on the health of citizens. By making and implementing this strategic document, the cities will provide the citizens and the business sector with the quality of life and business in the present and the future. Unlike the traditional approach to transport planning, SUMP places special emphasis on the involvement and participation of citizens and other stakeholders, and aligning decisions in various sectors: transport, urban planning, economic development, social affairs, health, safety, energy, etc. Joint decision-making should include stakeholders on all vertical and horizontal decision-making levels. In Croatia, there is no single accepted name and it is known by acronyms POMG, POUM. Urban traffic is the key energy user and causes most greenhouse gas emissions and therefore, regardless of the size and population, the cities have a key role in achieving the objectives of the European 2020 strategy and improving energy efficiency while reducing greenhouse gas emissions.
The European Commission has emphasized in many of its transport-related policy documents such as the Action Plan on Urban Mobility, the White Paper: Roadmap to a Single European Transport Area and the Urban Mobility Package that strategic approaches and the integration of transport planning policies with other policy sectors like environmental protection, land use planning, housing, social aspects of accessibility and mobility as well as economic development are needed.
There is wide consensus that sustainable urban mobility planning contributes to a better quality of life and is a way of tackling transport-related problems in cities more efficiently. Sustainable transport modes, which include cleaner vehicles and public transport as well as cycling, walking and intermodal modes such as taxi and car sharing, should play a major role in future urban transport systems. Cities should apply different measures in order to promote the use of these modes.
The European Commission promotes sustainable urban mobility planning in order to enhance transport planning processes. A Sustainable Urban Mobility Plan (SUMP) is a strategic document designed to contribute to meeting European targets. It builds on existing planning practices and takes due consideration of integration, participation and evaluation principles. It is the result of a structured process that comprises status analysis, vision building, objective and target setting, policy and measure selection, active communication, monitoring and evaluation – and the identification of lessons learnt.
The basic characteristics are:
Consideration of external costs for all transport modes.
