Review both domestic and overseas pedestrian flow characteristic research results. Enumerate our country’s research achievements recent years. Introduce that the domestic scholars draw the pedestrian speed characteristic and pedestrian flow model according to different time, place, environment and other cases. Examples show that the pedestrian speed characteristic and pedestrian flow model has certain differences. For example, most domestic scholars describe speed - density relational expression with dynamics model, logarithmic model and linear model. This paper proposes that establishes reliability index for different pedestrian flow model, studies how different facilities affect the pedestrian flow characteristics, and establishes data reference standard for pedestrian flow characteristic.
