| Summary: | Walkability is one of the issues to be addressed in the planning of smart urban cities. Although, there is a substantial amount of studies on outdoor walking pedestrian, limited study has been done to address indoor walkability. Therefore, this study discussed the development of 3D indoor model to visualize the indoor walking environment carried out using mobile mapping system. The handheld scanner is used for its convenience to access narrow space and complex building structure. The indoor layout of the building is captured using this system by producing point clouds that represent the indoor environment. The building geometry and facilities are determined by point cloud segmentation to segment the same points into one group. The generation of 3D floor plan from point cloud provided a good visualization of indoor model and walking environment. The extraction of vector walking path is also useful to be displayed with the indoor model to make it easier for the pedestrians. The main objective of this paper is to determine the indoor walking path using mobile laser scanning. The define indoor walking path will be used to calculate the walkability index on the indoor building. Therefore, the calculated walkability index can enhance the walking behaviour by improving the facilities in the indoor building. © Published under licence by IOP Publishing Ltd.
