Abstract
Urban population is steadily growing worldwide, while the number of people in Eastern Europe is decreasing. These two contradictory trends have outlined the proposal for sustainable solutions to solve civil engineering issues that are aimed at implementing the principles of sustainable development and ensuring a better quality of urban life. When considering the problem that is encountered in Eastern European countries, a multi-criteria model for sustainable urban development has been designed and focused on planning and simulating an inner urban living environment. The suggested model has disclosed the social, economic, environmental, and sustainable components of the infrastructure that are necessary for developing inner urban areas. The components have been adapted and presented in three different size territories covering Lithuanian cities and towns. The applied expert evaluation method has assisted in determining the key criteria that should be considered in order to identify the most important inner areas of urban development. It is expected that this study will extend activities that are performed in the field of improvement of sustainability engineering processes and offer guidelines for other researchers investigating the areas of inner urban development.
Highlights
Urban population is steadily growing worldwide, while the number of inhabitants in EasternEuropean countries is decreasing and reallocation between different cities is taking place [1]
The problem originates from accelerating construction in the suburban area, because a large part of the urban population prefers this location as a place of residence
The opposite trend is evident when looking at variations in the space of the urban area
Summary
Urban population is steadily growing worldwide, while the number of inhabitants in Eastern. European countries is decreasing and reallocation between different cities is taking place [1]. The problem originates from accelerating construction in the suburban area, because a large part of the urban population prefers this location as a place of residence. The density of urban population decreases, the compactness of cities is diminished, the infrastructure of transport becomes more and more expensive, cars start playing the predominant role, inner urban development is paid less attention, and outer urban development is stimulated. To avoid the above-mentioned consequences and to find a possibility of balancing (symmetry) needs and their satisfaction, the promotion of inner urban development is necessary, and Symmetry 2019, 11, 406; doi:10.3390/sym11030406 www.mdpi.com/journal/symmetry
