Integration of citizens’ feelings and feedback into the city information modeling environment

A City Information Model (CIM) is a 3D model composed of the city structure and various interconnected city layers such as mobility, environment, and social inclusion. CIM has attracted attention in recent years, but improvements are still needed for data collection, integration, and visualization in CIM. Also, limited research is available on citizen participation and integration into CIM, which is crucial for realizing a human-centered digital replica of the city. This paper explains the thorough integration of both tangible and intangible data around mobility, road security, and social participation in CIM. The study embarks on the creation of a CIM prototype based on (1) integrating data from different sources, and (2) collaborating with residents to highlight specific feelings around the neighborhood. The general methodology comprises (1) data collection, (2) data analysis, and (3) platform build-up. This methodology is projected onto a selected neighborhood in Lille, France where collected quantitative and qualitative data is analyzed, and then visualized. This study can provide stakeholders and city planners with a means of decision-making to improve the quality of life in cities.
