Component

In this study, a methodology was developed for deriving vehicle occupancy using Wi-Fi based sensors under mixed traffic conditions. The methodology was field tested on an urban arterial road and an expressway. Vehicle occupancy derived from the methodology was observed to vary with respect to traffic volume. Higher values of occupancy were obtained for higher flow and vice-versa. Further, larger variation in occupancy values was noted at higher traffic volume levels as compared to lower traffic volume levels, highlighting the proficiency of the developed methodology to derive vehicle occupancy. The derived occupancy values were then validated through questionnaires and were observed to be in close match with each other, further corroborating the robustness of the developed methodology.
