A Microclimate Study of Traffic and Pedestrianization Scenarios in a Densely Populated Urban City

Abstract EN

Urban streets are known to have a significant role in creating urban microclimates.

This study aims to empirically quantify temporal and spatial microclimate variation within the same street configurations with pedestrian schemes.

To evaluate the urban microclimates at the pedestrian level, a detailed monitoring project was performed at five representative locations near intersections, within a busy street canyon of the typical urban community in a densely populated urban city.

Monitoring was done for warm and cool seasons.

A strong, significant correlation (p<0.01) was found under multiple time scenarios (traffic, nontraffic, and as a whole) and for both seasons.

These findings suggest that the average urban daily temperature was not significantly reduced when there was no vehicular traffic present, whereas pedestrian activity contributed to urban heat regardless of the season.

These findings provide an essential foundation for further studies on urban microclimates within pedestrianized areas and will likely lead to better urban design and policy management, especially concerning thermal comfort and Quality of Life at the pedestrian level.
