As one of the biggest megatrends of the 21st century, urbanization affects both recent and established industrial countries. In the European Union, already more than 70 percent of the population live in an urban area. In Germany, the uninterrupted urban growth is likely to pose huge challenges for many municipalities in the future, in areas like traffic, energy, environment and health. For this reason, innovative solutions in terms of city planning and city development are required. Additionally, increasingly demanding citizens expect a high quality of life and improved citizen services. To address those challenges, traditional routes must be tested, old infrastructures modernized and administrative processes organized more efficiently.
