A pilot study, conducted by Houston Public Media, shows that tree shade is an effective and consistent form of cooling for transit riders. After taking temperatures at 21 bus stops in July and August, we found that bus shelters often reached temperatures that pose an "extreme threat" of heat illness. In some cases, bus shelters were hotter than standing in direct sunlight. Tree shade on the other hand was on average twice as cool as bus shelter shade, and tree shade never made the heat worse.
