cta_bus_predictions

Pack: cta · Endpoint: https://gateway.pipeworx.io/cta/mcp

Chicago CTA bus tracker arrival predictions at a bus stop — route, destination, predicted minutes until arrival (“DUE” = arriving now), delay flag, and vehicle id. Pass stop_id (the 4-5 digit stop number posted on CTA bus-stop signs), optionally with route. If you only know the stop by name, pass route + find_stop (a street/intersection fragment like “clark & madison”) and the stop is looked up for you. Example: cta_bus_predictions({ route: “22”, find_stop: “addison” })
