Dense urban areas restrict air movement, causing airflow in urban street canyons to be much lower than the flow above buildings. Boosting near-ground wind speed can enhance thermal comfort in warm climates by increasing skin convective heat transfer. We explored the potential of a wind catcher to direct atmospheric wind into urban street canyons. We arranged scaled-down models of buildings with...

The existence of bottlenecks often leads to the stagnation pedestrian gatherings, which seriously affects efficiency traffic and reduces flow pedestrians. Some studies have shown that setting devices in front can promote evacuation under certain conditions. In this paper, effect diversion exit on is studied. From our observation, these form a buffer zone before affect behaviors. times are found...

The focus of the thesis is the utilization of the data collected using state-of-the-art tracking technologies for the characterization and modeling of pedestrian movements. In this context, the main objectives are the development of (i) data-driven definitions of fundamental variables and (ii) data-inspired mathematical formulations of fundamental relationships characterizing pedestrian traffic...
