This study aims to develop a microscopic pedestrian behavior model considering various
interactions on pedestrian dynamics at crosswalks. Particularly, we take into account the
evasion behavior with counter-flow pedestrians, the following behavior with leader pedestrians,
and the collision avoidance behavior with vehicles. Aerial video data at one intersection
in Beijing, China are extracted for model calibration. A microscopic calibration approach
based on maximum likelihood estimation is applied to estimate the parameters of a modified
social force model. Finally, we validate step-wise speed, step-wise acceleration, step-wise
direction change, crossing time and lane formation phenomenon by comparing the real data
and simulation outputs.
