Abstract
In order to estimate the heat stroke risk in street space, we had measured the air temperature distribution of the center of Tokyo in summer. From the results of measurement, there was a tendency which becomes higher temperature of street space than Tokyo District Meteorological Observatory. And the variation of temperature by a point was also great, the difference of those amounted to 3 ℃. Although the forecast of heat stroke is made by the value of Meteorological Observatory, it is important that the higher potential of heat stroke is existed at street space in urban area. In the risk assessment of street space, it is important to take street composition and weather condition into consideration.
