Abstract

The wind speeds in pedestrian spaces for staggered rectangular block arrays derived from large-eddy simulations are analyzed to model the urban pedestrian wind environment. The authors defined the area within 3 m of block walls as the pedestrian space and compared wind speeds in it under various geometric conditions. According to the result, the wind speeds in pedestrian spaces are influenced by the plan area ratio (λp) and block aspect ratio (αp). In addition, an exponential equation in terms of λp and αp can estimate the wind speed ratio well at the pedestrian level, especially for regions in front of blocks.
