Crowd density estimation and pedestrian counting are becoming an area of interest such as assessing the social effect and impact between small groups of people within a crowd. Still, existing experimental crowd analyses performed by operators are time consuming. Generally, human controllers are engaged to achieve this task, however, more and more, visual surveillance are becoming an essential n...

Pedestrian safety is becoming a global concern and an understanding of the contributing factors to severe pedestrian crashes crucial. This study analyzed crash data for San Antonio, TX, over six-year period understand effects pedestrian–vehicle crash-related variables on injury severity based party at fault identify high-risk locations. Bivariate analysis logistic regression were used most sign...

Crowd simulation is used for evacuation and crowd safety inspections, study of performance in crowd systems and animations. Cellular automata has been extensively used in modelling the crowd. In regular cellular automata models, each pedestrian occupies a single cell with the size of a pedestrian body. Since the space is divided into relatively large cells, the movements of pedestrians look lik...

The purpose of this study is to identify human walking vertical force by using FFT power spectrum density from the experimental acceleration data of the human body. An experiment on human walking is carried out on a stationary floor especially paying attention to higher components of dynamic vertical walking force. Based on measured acceleration data of the human lumbar part, not only in-phase ...

Walking, as an important transportation mode, plays a large part in urban transportation systems. This mode is of great importance for planners and decision-makers because of its impact on environmental and health aspects of communities. However, this mode is so complex in nature that makes it difficult to study or model. On the other hand, chaos theory studies complex dynamical nonlinear syste...

Conventional indicators using crowd density and pedestrian speeds can’t evaluate the walking condition of each pedestrian. This study aims to analyze acceleration elucidate relationship between them ease walking. For this research, mingling flow reproduction tests were carried out inside a motion-capture facility. Then, new graphic representation was created visualize acceleration. Furthermore,...

a pedestrian is every person who is walking, especially along or the width of a street or other place used by cars. growth, development and industrialization of societies, threatens the safety of pedestrians. increase and acceleration of vehicles and traffic, lack of road and street standards, weakness of laws or inappropriate executive guarantees, causing to insecurity and incidence of physica...

This paper describes the system to take traffic lines of pedestrian flows outdoors and the investigation of dynamic characteristics by using the density, direction and velocity distribution of them. These characteristics express the congestion and latent dangerousness of field. Also the arrangement of structures and public facilities will be evaluated.
