Most bus stops are a sign on a pole. In a desert metro, that is a health risk for riders who are disproportionately older, lower-income and without a car.

This example petition asks the agency to publish a ranked list of stops by boardings and heat exposure, commit to a number of shade structures per year, and report progress publicly.

Adapt it for your own agency by citing its ridership data and any heat or climate action plan it has already adopted.
