A Study on Understanding Pedestrian Flow Using Intermittent Recording Images (PIRI)

Abstract

Pedestrian flow information has been used as the basic data for urban facility planning and architecture. Pedestrian information surveys require significant time and money. Therefore, this study assesses pedestrian flow using intermittent recording images (defined as "PIRIs" in this paper).A PIRI makes it possible to visualize the state of pedestrian flow and is developed as follows: 1) Pictures of pedestrian flow are taken from a stable viewpoint.2) These continuous pictures are imported into an analyzing platform (some type of a PC).3) The offset of these images caused by camera movement is adjusted to the correct position. This process can be executed automatically.In this study, the optimal shutter interval was defined as t = 1 s, and the number of images processed is defined as Tmax = 20 [frame]. Using these parameters, PIRI can be applied with "time-space interfering model *1.

Designing Guidelines for Metro Stations in Developing Countries: The Case of Dubai

“…Therefore, many factors need to be considered when designing a metro station such as the flow design inside the building, the impact of sun radiation on the roof, which in return affects the interior spaces of the building thermally, thus altering the pedestrian comfort level and leading to increased use of air conditioning, and others like the effect of wind flow on the building, the building services, complex shapes and geological conditions (Dunnicliff, 1993). Takayanagi, Yamada, and Shibahara (2015) stated that it is becoming more important to assess pedestrian flow today, where it has been used as the basic data for congestion and comfortable space planning for urban facilities and architecture. Herein, this research merges together thermal studies with the flow of people in Dubai metro stations because all the roof forms of metro stations are similar.…”
