Abstract: Pedestrian traffic plays an important role in urban traffic system, research on mixed traffic, capacity and delay of intersections can never be complete without the consideration of pedestrian traffic. Pedestrian walks freely at all directions, as a result, data collection is difficult for pedestrian research. Based on pedestrian traffic, this paper discussed the ways of pedestrian data collection. From three aspects of particularity, diversity and continuity, this paper discussed applicability of various data-collection methods, and analyzed manual method, GPS observing method and video observing method. It is significant for pedestrian traffic.
