Flow evaluation of pedestrian´s field with traffic lines

This paper describes a system to extract traffic lines of pedestrians flow outdoors and the investigation of dynamic characteristics by using the density and direction 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. Furthermore, this paper presents pedestrian´s field evaluation focused on flow. These characteristics parameters are profitable for evaluation of environmental design.
