This chapter focuses on the use of digital technologies in urban regeneration processes at the scale of the neighbourhood. Between 1950 and 1980, hundreds of neighbourhoods were built all over Europe, and the planning principles underlying them were also used in urban regeneration projects of rundown historical areas. With few exceptions, the planned urban neighbourhoods started to face social and economic problems a few decades after their construction. They became the scene of reconstruction and revitalization processes that usually take the scale of the original neighbourhood as their starting point. Contemporary regeneration approaches proposed for those areas are not limited to the physical and functional improvements; they put much attention to the existing communities, their needs, and aspirations. Cooperation between professionals and residents has become of paramount importance. The increased complexity of the neighbourhood-improvement programmes demands an interdisciplinary approach that addresses urgent issues, such as the ageing population, (un)healthy living environments, climate-change adaptation, etc. Where different professions get engaged with the residents, speaking a common language is crucial from the initial phase of setting the grounds. One of the major obstacles planners in neighbourhood regeneration processes encounter is how to connect citizen knowledge to their professional expertise. Interactions and visualizations based on information and communications technology (ICT) can help to create a common language, offering a realistic impression of the desired results of interventions and their impact on safety, health and well-being. This chapter offers insights into the case studies from Groningen, Ljubljana and Lyon.
