Simulation and Analysis of Influencing Factors of Pavement Thermal Environments in Guangzhou

Pavements are closely related to the livelihoods of urban residents as an important part road system. Based on early field measurements our team, we found that plant spacing, pavement orientation, and material influence thermal environment. Our objective was quantitatively evaluate various factors pavements in Guangzhou along West Zhonghuan Road, University. team’s previous research, environment-met (ENVI-MET) numerical simulation software used simulate under different orientations, underlying surface materials, distances. Quantitative analysis effects factor combinations temperature, humidity, wind speed, physiological equivalent temperature (PET), radiant (Tmrt) performed. The results show among affecting environment pavement, street tree spacing have greatest effect pavement. direction is negligible; however, it has a significant speed. There no difference air relative humidity between concrete asphalt. average red floor tile slightly lower than asphalt concrete. Reducing trees can effectively reduce penetration direct solar radiation, improve pedestrian walking comfort. serve reference for design wellbeing citizens promote environmental sustainability.
