In order to effectively depict the queuing state of pedestrians at the exit of interior space, a new pedestrian evacuation model is proposed based on cellular automation and S-queue. This model firstly defines the calculation equation of the pedestrian movement probability based on the floor field and queue length, and derives the calculation equation of queue length according to the S-queue theory. Finally, pedestrians are organized for real evacuation in the interior space, and an experimental platform is constructed for simulation analysis according to the real environment, and the relationship between parameters, e.g., exit width, evacuation time, queue length, evacuation velocity and pedestrian density, etc. are studied in depth. The results show that the evacuation strategy that emphasizes the queuing effect helps to reduce the number of pedestrian in queue, especially when the crowd density is larger, such strategy can effectively reduce the evacuation time.
This paper systematically studies the structure of bamboo and the schematic prototype of traditional bamboo wares, deeply analyses the design elements of bamboo from the aspects of shape, texture, character and cultural connotation, and summarizes its artistic aesthetic implication and morphological characteristics. Combining with design practice, this paper verifies the feasibility of using bamboo in product design, and explores the infiltration and transformation mode of traditional bamboo culture in modern design, so as to realize the inheritance and development of traditional art resources. The research shows that the traditional bamboo cultural resources as the intrinsic motive force of modern innovative design effectively enhance the cultural connotation and artistic value of the design object, and meet the requirements of sustainable design development, which provides references and practical ideas for bamboo creative product design.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
