This is the dataset of the National Center of Sustainable Transportation (NCST) project titled A Survey of Agencies on Mitigating Extreme Heat Exposure through Novel Materials and Improved Pedestrian Infrastructure Design. This project reviewed the growing literature related to the application of ANMs and GSI to reduce UHI effects and implemented a survey of urban planners and public works engineers to assess the current and planned use of these strategies. The survey also asked respondents to identify barriers to implementing heat mitigation strategies within their pedestrian infrastructure systems.
