Abstract:This paper mainly introduces three evaluation indexes: pedestrian weaving intensity, density factor of weaving points in pedestrian weaving zone and pedestrian trajectory offset ratio. By means of controlled experiments, some parameters are analyzed quantitatively, namely the volume of the areas inside railings as well as two sub areas behind railings, the location of the pedestrian weaving zone(PWZ), the area of PWZ and the value of pedestrian trajectory offset ratio. Then, the judgment standards of whether setting railings makes pedestrian flow orderly and whether the railings play a role of current limiting were put forward, along with the judging process. Afterwards, two Shanghai urban rail transit stations in Shanghai were selected for case study, evaluating the validity of setting railings. It is anticipated that this research will put forward a quantitative analysis method for the planning and design of the railings.
