Abstract
Although there are numerous studies that explain how pedestrians behave, there remains a lack of experimental data on the various factors that can induce walking speed changes. It is important to continue experiments into this topic because, given that pedestrians receive information and select paths during indoor wayfinding in complicated buildings, their walking speed necessarily decreases. Furthermore, the majority of existing studies do not simultaneously explain changes in indoor wayfinding characteristics and in walking speed. To bridge this gap, we present results from an experimental study to indicate the effect that wayfinding at intersections within a building has on human walking speed. We analyzed changes in walking speed by intersection type and path selection direction (by conducting a maze experiment with 77 participants) to arrive at the following results: (a) Human walking speed decreases at intersections; (b) The change in walking speed depends on the type of the intersection and the path selection direction; (c) A multiple regression analysis can be used to model reduction in walking speed by intersection type and path selection direction. This study suggests that evacuation modeling should consider that wayfinding occurs when pedestrians select paths at intersections, which affects their walking speed.

  • Pretraining has recently greatly promoted the development of natural language processing (NLP)
  • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
  • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
  • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
  • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
