Many cities aim to progress toward their sustainability and public health goals by increasing use of transit systems. However, without adequate protective infrastructure that provides thermally comfortable conditions for riders, it can be challenging reach these in hot climates. We took micrometeorological measurements surveyed riders about perceptions heat heat-coping behaviors at bus stops with a variety design attributes Phoenix, AZ, USA, during the summer 2018. identified coping made feel cooler. observed current standards material choices Phoenix are insufficient provide thermal comfort, even expose risks. Almost half study participants felt or very time they were surveyed, more than reported feeling uncomfortable. On average, shade reduced physiological equivalent temperature (PET) 19 °C. Moreover, we found significant diurnal differences PET reductions from provided various attributes. For instance, all effective reducing morning; however, vegetated awning did not statistically afternoon. Temperatures sun-exposed surfaces man-made materials exceeded skin burn thresholds afternoon, but was bringing same safe levels. Aesthetically pleasing rated as cooler less beautiful. conclude striving increase should prioritize comfort when designing
