Visit when the problem is strongest
A shelter that looks shaded in the morning may expose the waiting area in late afternoon. Observe at a representative hot hour and record the date, weather source, sun direction, queue location, and scheduled versus actual wait. Do not present one day as a complete climate study.
Follow the passenger’s path
Check the route from nearby crossings to the stop, the position of shade, accessible clear space, seating with backs or arms, legibility of information, and the boarding point. Advertising panels, parked vehicles, bikes, and utility boxes can redirect people away from the only shade or block mobility aids.
Distinguish shade from heat relief
Transparent roofs may block rain yet transmit solar heat. Dark benches and pavement can become uncomfortable, while enclosed panels can limit air movement. Trees, reflective canopies, ventilated structures, water access, and nearby cooled buildings each solve different parts of the problem and require maintenance.
Prioritize by exposure and consequence
Combine observed waiting time with ridership, transfer dependence, service frequency, nearby health and senior facilities, and lack of alternative shelter. Publish what can be fixed quickly—cleaning, information, temporary shade—and what requires capital work. Recheck after changes at the same time of day.
A shelter must protect the actual waiting place
Audit the route, queue, accessible space, boarding point, sun angle, and wait duration. A roof elsewhere on the platform does not reduce exposure.
