A stretch of approximately 850 m in the core of Kolkata Municipal Corporation (in India) has been delineated as the case area for this research. The 02 data sets considered for this research are: 1) Physical data: Pedestrian Count and Vehicular Traffic Volume, and 2) Cognitive data: Light Intensity, Noise, and Thermal Comfort. The authors collected the data from the case area in the years 2020 and 2021. This paper initially involves determining the pedestrian “Level of Service” (LOS) based on the pedestrian count. Furthermore, the authors co-relate (Pearson’s Correlation with a 95% confidence interval) the LOS data with the light intensity, sound intensity, and temperature data; to establish a relationship between them. The result of this research indicates that there is a gap in realizing the potential of walkability in the case area. The authors conclude that the improvement of cognition in pedestrian-level Universal Mobility can lead to a better physical environment for the specially-abled and elderly. Introduction There are 26.8 million specially-abled people in India as per the last census in 2011. Additionally, there are 103.8 million elderly people. 1 Along similar lines, the “United Nations Sustainable Development Goals” (UN-SDG) number 11 (Sustainable Cities and Communities) becomes more significant than ever in the Indian context. Universal Mobility is a fundamental component of “Sustainable Cities and Communities”, which suggests equal mobility preferences for all,  PhD (MEXT) Scholar, Laboratory of Architectural Planning (N216, Engineering Faculty), Division of Architectural and Structural Design, Hokkaido University, Japan.  Professor, Laboratory of Architectural Planning (N216, Engineering Faculty), Division of Architectural and Structural Design, Hokkaido University, Japan.  Associate Professor, Laboratory of Architectural Planning (N216, Engineering Faculty), Division of Architectural and Structural Design, Hokkaido University, Japan. 1.
