The recent rise in temperatures urban areas has raised concerns about various health problems, such as heat-related illnesses. This study quantified the number of individuals exposed to outdoor heat during daytime summertime waterfront area Tokyo. Conventional meteorological observation and administrative data are insufficient for high-resolution analyses people flow conditions environments. Therefore, this introduced a new methodology combining computational fluid dynamics (CFD) mobile phone global positioning system (GPS) data. A numerical simulation was performed estimate wet-bulb globe temperature (WBGT) by analyzing radiation models. WBGT parks determined be approximately 27 °C, while on-road exceeded 29 °C. Simultaneously, pedestrian density assessed collecting GPS data, revealing that pedestrians concentrated near stations, office areas, shopping districts within 5 km × area. Furthermore, review stroke cases (2010–2020) indicated yielded stronger correlations with than considering alone. Finally, risk index established, integrating heat, flow, aging rate, which more accurately predicted cases.

This study adapted the mean age of air, a time scale widely utilized in evaluating indoor ventilation, to assess impact building layouts on urban ventilation capacity. To distinguish it from its applications enclosed environments, index was termed effective air (τ¯E). Based an experimentally validated method, computational fluid dynamic (CFD) simulations were performed for parametric studies four generic parameters that describe morphologies, including height, density, and variations heights or frontal areas adjacent buildings. At breathing level (z = 1.7 m), results indicated three distinct distribution patterns insufficiently ventilated areas: within recirculation zones behind buildings, downstream sections main road, near lateral facades. The spatial heterogeneity capacity emphasized through statistical distributions τ¯E. In most cases, convective transport dominates purging process whole canopy zone, while turbulent prevails pedestrian zone. Additionally, comparisons with reference case simulating open area highlighted dual effects buildings notably enhanced dilution promoted by helical flows between also serves as preliminary CFD practice utilizing τ¯E homogenous emission demonstrates capability assessing potential planning.
