Evaluation of pedestrians flow by time transition of traffic line density distribution

This paper describes the system to take traffic lines of pedestrians flow outdoors and the investigation of dynamic characteristics by using the density, direction and velocity distribution of them. These characteristics relate to the congestion and latent dangerousness of field. They are difficult parameters defined with static images. The time transition of these characteristics shows the dynamic situations of them. Also by using these characteristics, it is expected that the arrangement of structures and public facilities will be evaluated.
