Raw and Processed Trajectory Data for Elderly Indoor Movement and Spatial Layout Evaluation (SPD Method)

This dataset contains the raw and processed indoor movement trajectory data used in the study “A Quantitative Method for Analyzing Elderly Indoor Trajectories and Its Application to Spatial Layout Evaluation.” The files include simulated behavioral trajectories generated from 36 residential floor plans, source code and output files related to the Segmented Perpendicular Distance (SPD) method, and classification results for turning intensities and morphological categories. The dataset also provides floor plan data and trajectory outputs for the Binhu Yayuan residential project used for validation. All data are provided to support reproducibility and further research on indoor movement modeling, human–building interaction, and aging-friendly spatial design.
