Research on Pedestrian Traversal Time in T-Shaped Passage

As the most common walking facilities in subway stations, passages usually have high density and complicated pedestrian flow. Different from previous researches on single passage, this paper mainly discusses T-shaped passage, a typical structure of combination of passages. In the event of an emergency, the T-shaped passage is likely to become a bottleneck point of traffic. Traversal time is an important indicator for evaluating the traffic efficiency. Firstly, we improved social force model based on the field survey. Secondly, we establish simulation scenes with different types of pedestrians and different widths of passage to describe pedestrians walking process in T-shaped passage. Finally, we analyze the influence of different factors on traversal time.
