This study delves into the relationship between urban morphology and the Urban Heat Island (UHI) effect in Manchester's transit-oriented development (TOD). Using various analytical methods, including context analysis, remote sensing, SPSS correlation and the Sankey analysis, the research examines both weekday and weekend data of Manchester Piccadilly and East Didsbury TODs. Remote sensing analysis reveals Manchester Piccadilly TOD as a UHI hotspot due to concentrated human activities and low Normalised Difference Vegetation Index (NDVI). East Didsbury TOD, on the other hand, experiences lower UHI intensity because of its lower building and population density. The findings highlight the significant impact of land use and urban morphology on UHI intensity. The paper highlights how TOD-generated commercial and entertainment activities contribute to UHI levels in different locations in Manchester. Factors such as high population density and a higher percentage of workers exacerbate the UHI effect in TODs. The relationship between building heights and UHI challenges the conventional assumption of a positive correlation between floor area ratio (FAR) and UHI. These insights are crucial for TOD planning, emphasising the need to carefully consider land use, population density, and building characteristics in shaping the TOD locations. Implementing measures such as reducing heat emissions from commercial and entertainment activities can lessen the UHI intensity. Providing effective shading in TOD streets and shortening the distance to transit stations can encourage sustainable transportation modes like walking and cycling. Ultimately, this paper enhances understanding of the intricate connections between urban morphology and UHI, facilitating the development of environmentally friendly TOD.
