The prototype of the extended citizen participation was developed based on existing urban participation platforms and extended by several functionalities. In urban participation, citizens are informed about the planned project with the help of provided information, and the objective of the participation is described. The prototype of the advanced citizen participation includes a description of a fictitious urban project, an interactive map that provides further information and can be read out, and a criteria-based feedback system. This is enabled by an AI model, which enables automated analysis and quantification of citizen contributions. Participants can thus receive feedback and examine whether the desired topics have been covered. The AI system only quantifies whether desired subjects have been covered, not the participant's position on them. In addition, the criteria can be weighted using priorities to express relevance, providing further information for evaluation and developing a project vision. You can try out the extended citizen participation prototype using a fictitious urban project and we appreciate feedback that we can consider for future prototypes.
