Participation platforms can be used to continuously involve citizens in municipal decision-making processes. The platforms act as a central place where citizens can find information about construction or redesign projects. The project locations can be displayed on a map, where citizens can submit and discuss wishes or suggestions with a spatial reference. In this way, opportunities for participation can be created both at the beginning of a construction project and in later phases, and traditional on-site participation formats can be supplemented. The use of a participation platform not only makes it possible to inform citizens about various projects over longer periods of time, but also establishes a place with recognition value that creates trust and thus promotes continuous participation. Cities that successfully use participation platforms include Hamburg and Barcelona.
