N2 - To solve the problem of insufficient understanding of the potential dangers caused by crowd intervention in the process of implementing the channelization strategy at the entrance of pedestrian passage, a safety assessment method of channelization strategy was proposed. Firstly, from the micro perspective of pedestrian movements, the characteristics of the channelization strategy on the whole process of multi-directional crowd inflow-canalization-confluence were analyzed. Then, the indicators reflecting the orderliness, rapidity and fairness of the whole confluence process were designed based on channelization length, channelization time, and direction change angle, and a three-stage safety evaluation method of the channelization strategy was formulated. Finally, the crowd channelization experiments were carried out based on the actual characteristics to reveal the influence mechanism of confluence direction, the channelization spacing and motion area on the sensitivity of evaluation parameters. The results show that the hierarchical regional distribution of orderliness and rapidity indicators can better reflect the risk characteristics of crowd conflict and crowding in the outer diameter of the lateral confluence and the central axis of the channel. Compared with "two persons wide" channelization strategy, the "one person wide" channelization strategy generates a more balanced interactive feedback on the crowd movement of different confluence directions, and with the increase of the number of entrance confluence directions, its safety promotion is better. © 2022 China Safety Science Journal.
