Analysis Of Microscopic Characteristics Of Local Pedestrians In Subway Stations

With the development of urbanization,the growth of urban population,the problem of traffic congestion is becoming more and more serious.Due to the large passenger capacity and fast operation speed,urban rail transit has a greater sharing rate in the mode of transportation.During the peak passenger flow period,the subway station has a large pedestrian flow,and the pedestrian movement route is intertwined.It is prone to crowding at various service facilities,resulting in a series of safety problems.Therefore,scientific and reasonable organization of pedestrian flow,standardizing pedestrian movement,in the subway Station operation management and passenger safety are of great significance.This study is based on the pedestrian trajectory of subway station passages,gates and platforms to explore the microscopic characteristics of pedestrians,analyze the rules of pedestrian movement,and provide suggestions for the improvement of traffic organization.According to the pedestrian trajectory,the channel analyzes the horizontal distribution and lateral offset of pedestrians,and studies the spatial preference and range of motion of pedestrians in lateral movement.The typical transcendence behavior and the opposite avoidance behavior are selected,and the characteristic parameters such as pedestrian lateral spacing,longitudinal spacing,lateral offset and straight walking distance are analyzed to explore the main laws of transcending behavior and opposite avoidance behavior.According to the speed change of pedestrians in the operation of the channel,the pedestrian interweaving intensity,and the pedestrian lateral displacement rate,the pedestrian movement limitation model is constructed to judge the pedestrian comfort,and the pedestrian movement state is graded according to the actual survey data to provide the guardrail setting.in accordance with.According to the movement law of pedestrians,the gates divide the movement of pedestrians into several stages,focusing on the selection of the gate selection stage and the pedestrian movement law of the gate passing stage.Through statistical analysis of trajectory parameters such as pedestrian lateral migration and longitudinal walking distance,the lateral motion characteristics of pedestrians are studied.Pedestrians have preference in the selection of gates,and tend to be balanced with the change of flow.Based on the pass rate and arrival rate of pedestrians,the range of influence of pedestrians in front of the gates is explored,which provides an optimization basis for the number of gates and the way the gates are laid.The platform layer analyzes the movement trajectory of the pedestrians entering the platform according to the stairs through different positions,and explores the causes of the different streamlines.Based on the queuing distribution of pedestrians in the boarding and landing area,the model of waiting position for people is changed,and the distribution of pedestrian distribution is optimized according to the law of pedestrian movement.The queuing characteristics of the pedestrian and landing areas where pedestrians are mainly gathered are studied.According to the obstacle setting of the platform,the station waiting is divided into a restricted riding and landing zone and an unrestricted riding and descending zone.The queuing is divided into a static zone and a dynamic zone according to the pedestrian movement state,thereby correcting the platform width.
