Bidirectional pedestrian movement is predominant on undivided stairways. Under a given situation, it is imperative to assess the level of service (LOS) provided to pedestrians on a stairway. Currently, limited guidelines are available for assessing the LOS on undivided stairways in South Asian countries. With this motivation, the current study was conducted to develop LOS criteria for undivided stairways by using the case of a busy suburban railway station at Dadar in Mumbai, India. The LOS can be considered as the classification of different pedestrian flow states on the basis of facility performance. This study is focused on employing the k-means clustering technique to define the LOS thresholds of relevant flow variables. Data on four major variables of pedestrian flow are used: space per pedestrian, flow rate, walking speed, and volume-to-capacity ratio. Derived LOS thresholds are then delineated by using the rate of change in slope for the average walking speed of pedestrians. LOS thresholds are further validated for different percentile values of pedestrian flow data to check whether given data sets fall within the range of established LOS thresholds. Ranges of the flow parameters defined for LOS criteria found in this study are significantly different from those reported in the literature and in manuals in developed countries such as the U.S. Highway Capacity Manual. This difference may be attributed to the demographic and sociocultural characteristics of the pedestrians. The results and approach adopted here can be useful for practitioners to assess the LOS of stairways operating under similar pedestrian flow conditions and to respond appropriately for their improvement. The study results can also be useful for the ongoing project of developing a highway capacity manual for India.
