Pedestrian traffic flow relationships and characteristics are the key theories to support the planning and design of walking facilities. For different types of facilities, pedestrian traffic could be longitudinal (unidirectional or bidirectional) flow, cross flow or multi-directional flow. Thispaper focuses on longitudinal pedestrian flow on confined passageways. Ittakes confined level passageway, ascending stairway, descending stairway and two-way stairway in Shanghai Metro stations with massive passenger volume as observing objects for data collection. Pedestrian flow parameters including volume, density and speed under comparatively full operation states from low density to high density are acquired by video recording. The overall trends of relationships among pedestrian volume, density and speed are analyzed with scatter plots. In full consideration of significance of statistic regression results and consistency with realities, pedestrian traffic flow models about speed-density and volume-density relationships areestablished for all the observed facilities. Furthermore, combined with walking behavior, the tendency characteristics of built models are discussed by cross-comparison analysis under the differences of walking facilitiesand traffic operation conditions. The collected data, built models and revealed pedestrian flow characteristics could be helpful to improve the theories on pedestrian traffic flow and be valuable references to similar pedestrian contexts studies.
