Optimum wind environment design for pedestrians in transit-oriented development planning

This paper discusses the influence of buildings on the surrounding wind environment in a high-density area with a transit-oriented development (TOD) planning concept. TOD requires the support of public transportation, and therefore it emphasizes better pedestrian walking environments. Based on the preliminary scheme, a subway station in Shanghai is selected as the research area, and the wind environment of the main pedestrian walking space is analysed. Wind environment simulations are carried out for various architectural designs. The best scheme is determined through a comparison analysis of the wind environment for pedestrians. The research results show that by proper consideration of the prevailing wind direction, a good wind environment can be created by a proper building design using TOD planning where there is high density development. The findings of this paper have significance with regard to urban architectural designs near subway stations.
