StepFree

Step-free trips on the New York City subway. Ask for a trip and an agent returns a candidate route that names the working elevator it depends on at every boarding, transfer and exit, checked against the live MTA outage feed.

A subway route is only step-free if every elevator it needs is working, and elevators go out all day.

The build

MTA elevator and accessibility data lives in Sanity, and outages refresh every 15 minutes. The route search only boards, transfers or exits where a working elevator serves that line, and it refuses outage data more than an hour old.
