There is an increased awareness of the importance of active non-motorized modes of travel. Therefore, pedestrian behavior studies are receiving a growing attention from policy makers, researchers and practitioners. A solid understanding of pedestrian walking behavior is necessary for the evaluation of measures associated with walking conditions such as comfortability and efficiency. Gait analysis is one of the useful approaches for analyzing pedestrian behavior at the microscopic level. The goal of this paper is to examine the spatio-temporal parameters of pedestrian gait (step frequency and step length) by means of automated video analysis to understand pedestrian walking behavior beyond the analysis of walking speed. The main outcome of this microscopic-level analysis is to provide an insight into pedestrian walking mechanisms and the effect of different characteristics such as gender and age. The results showed that gait parameters are influenced by pedestrian gender, age, group size, crosswalk length, and pedestrian signal indication. Pedestrians were found to have the tendency to increase their step length more than their step frequency to increase walking speed. It was also found that, compared to males, females generally increase their walking speed by increasing their step frequency more than step length. However, when in non-compliance with signal indications, females increase their walking speed by increasing their step length more than step frequency. It was also found that older pedestrians do not significantly change their walking behavior when in non-compliance with signal indications.
