Simulation of pedestrian flow represents an advanced approach in modeling and evaluating train stations. In this study, pedestrian simulation was done using the simulation software Simio to assess the passenger capacity of MRT 7 Station 1-North Avenue Station through level of service (LOS), queuing system, and train facility utilization. This paper presents the actual situation inside the train station while predicting the behavior of queuing pedestrians and provides an accurate estimate of the volume-to-capacity ratio of passengersentering the station. The study’s approach debugged the conventional assignments of pedestrians currently used in the field. The constructed three-dimensional building of the North Avenue Station served as framework for the simulation. Sources, sinks, servers, and paths of the software were the main elements of the simulation. Each library was defined by their time usage based on data gathered. Time usages of 1.21 sec. and 240 sec. for sources and sinks, respectively, were used in the simulation. Servers were defined by the train facilities utilizedin the simulation, namely, automatic ticketing machines (TVM) with time usage of 43 seconds, ticketing toll gates with 1.4 seconds, and manual ticketing windows (BOM) with 20 seconds. In addition to the libraries,pathsthat provided the flow, direction, and distribution of pedestrians were calibrated using 10% for TVM users, 35% for BOM users, and 55% for others (regular tickets, beep cards, promo trips) based on data obtained. Simulation results showed that the new proposed plan has a higher passenger capacity than the original plan.
