The social aspects of urban development and transport areas are various, and the prospect of extracting and using them is abundant. In this respect many other aspects should be incorporated in order to get desired results. The concept of sustainable development may not be implemented without incorporating social, environmental, and economic issues. However, this concept is changing as a result of changing the social/human needs and engineering opportunities. There are discussions among the urban and transport planning communities concerning the inclusion of other factors to the concept of sustainability. Based on above-mentioned assumptions, this paper discusses the essentials of social aspects of urban development and transport. It describes the role and position of human factor in urban development and transport planning and its interface with technical elements. The paper argues the possibilities of optimization of the relationship between human factor and technical elements using the socio-technical insights related to Smart Growth and Intelligent Transport Systems. The research methodology has been based on empirical and theoretical approaches. The working methodology has been based on the concept of organizational science emphasizing the importance of balance between human health, well-being and effectiveness.
