Stair Width, Pitch and Alignment in Stair Climbing and Descending Rates

Innovative interventions in the planning and design of stair and escalator facilities call for understanding their effects on stair use. This study considers five planning variables for the twinned stair and escalator facilities–stair pitch and width, angle of deviation, height and separating distance. Public sites were identified in 8 commercial districts in Beijing. Facilities (n=21) presenting heterogeneously across variables were sampled for simultaneous up and down pedestrian counts in 18 5-minute video segments middays, for a total of 1464 counts. Stair width accounts for 20% of the variance in ascending rate and 10% in descending. Plan angle accounts for 2% in ascending and 5% in descending, while pitch accounts for 1% in ascending and 5% in descending. The study confirms the effects of layout and design of stairway and escalator facilities on facility choice. The results point directly to interventions in support of higher stair-climbing rates.

Systematic Planning of Pubilic Art in Suzhou-City

Urban sculpture works is a huge system what include the level, the sequence structure when you examines carefully from the plan angle, therefore the urban sculpture system planning is a special plan in the level of master plan. The research of suzhou sculpture system plan has been clear development idea of city sculpture and analyzes he control essential factor based on the urban public space resources and refined the subject and the theme from Suzhou region characteristic through the plan experience of our cities’ sculpture development and the plan. The urban sculpture system has a distinctive style, and the extremely rich feasibility of the plan implements and manages.
