This paper presents a method to safely organize the indoor space pedestrian flows. To quantitatively describe the indexes related to pedestrian safety, a capacity estimation model is proposed for the number of participants, and then the characteristic of pedestrians of different age is considered in analysing pedestrian speed by using step frequency data. Furthermore, we develop a pedestrian safety estimation model and obtain the probability of safe crossing. Based on the estimation results of capacity model and safety estimation model, a reasonable scheme of pedestrian organization is put forward. Finally, a case study is adopted to apply the proposed models.
