64% of Houston Metro bus stops have no shelter, exposing riders to 92°F+ wet-bulb temperatures that cause heat illness

In Houston, Texas, the majority of bus stops are a bare pole with a sign. No roof, no shade, no bench. As of 2025, 64% of Metro bus stops have no shelter at all. Riders — disproportionately low-income, elderly, and disabled — stand in direct sun while waiting for buses that may be 15-30 minutes apart. A UTHealth Houston study measured wet-bulb globe temperatures (WBGT) averaging 92.5°F at unsheltered stops during summer, a level the CDC classifies as posing significant heat stress risk. Houston Public Media's "Hot Stops" investigation found at least 16 calls to 911 from people at bus stops for temperature-related emergencies in just June and July of one summer, plus roughly 200 calls classified as "unconscious person" or "sick person" at bus stops during the same period. The reason this matters beyond the immediate health risk is that it makes the bus a physically dangerous mode of transportation for a significant portion of the year. Houston's summers regularly exceed 100°F for weeks. A rider waiting 20 minutes for a bus in direct sun at 95°F ambient temperature isn't just uncomfortable — they're at medical risk for heat exhaustion and heat stroke. This effectively makes bus transit seasonal for vulnerable populations: elderly riders, people with chronic conditions, and parents with small children avoid the bus in summer because the wait is dangerous. That drives them toward cars they can't afford or keeps them home, cutting them off from jobs, medical appointments, and social participation. The problem persists for structural reasons tied to land use and property rights. Many bus stops sit on narrow sidewalks where there's physically no room for a shelter. Others are on private property frontage where the transit agency needs easements that property owners won't grant. The cost of a single bus shelter installation ranges from $10,000 to $50,000 depending on design and permitting, and Metro has roughly 9,000 stops. Even at scale pricing, sheltering every stop would cost hundreds of millions of dollars — money that competes with vehicle procurement, driver salaries, and route expansion. Metro has added about 1,000 shelters recently and plans 2,000 more by 2026, but at 9,000 total stops, full coverage is decades away at current pace and funding.
