Fundamental Diagrams of Pedestrian Flow Characteristics for Stairs: A Case Study of Delhi Metro Rail Station
Understanding the pedestrian flow characteristics on stairs helps in estimating the capacity of a pedestrian facility accurately as they are crucial infrastructural elements in evacuating pedestrians in normal as well as emergency situations. The pedestrian flow characteristics in congested and uncongested conditions can be best explained by fundamental diagrams which show the relationship between speed-flow-density. In this regard, the present study aims to develop fundamental diagrams of pedestrian flow characteristics for stairs in Indian scenario. Pedestrian data has been collected on ascending and descending stairs of New Delhi metro rail station for unidirectional and bidirectional pedestrian movements. Initial analysis show that the data extracted from peak and non peak hours together produces only uncongested portion of the fundamental diagram. To obtain the congested portion, this study employed simulation method. To obtain the simulation results accurately, walking speeds of pedestrians with respect to different pedestrian attributes such as gender, age and luggage were obtained and used as input for simulations. Finally, design values of pedestrian flow characteristics for stairs are obtained and compared with the existing guidelines and studies. It is observed that the maximum density and density at maximum specific flow values for stairs proposed by Indo HCM (2017) are higher compared to the design values obtained in this study. It is anticipated that the results of this study provides insights into development of fundamental diagrams of pedestrian flow characteristics for stairs.
