Abstract: Abstract Similar to vehicle traffic, pedestrian flow can also be classified as heterogeneous. This paper introduces the concept of equivalent factors for converting mixed older adults and commuter pedestrian flow into equivalent commuter flow. The methodology employed was derived from vehicle passenger car equivalent (PCE) methodologies. Pedestrian micro-simulation models are utilized to generate data for the pedestrian time-space (TS)-flow relations where flow equivalency is derived. Data for the model input and calibration and validation were collected for commuter-only traffic and older adult and commuter combination. Results from the model were used to create the TS-flow relationship and pedestrian equivalent factors calculated. An application of the equivalent factor illustrates the importance of considering heterogeneity in pedestrian walkway design. This methodology can be adopted to compute other equivalent factors for other pedestrian types considering local pedestrian characteristics.
