The city's subways are number one in the nation.

That's according to a new study by urban planning company Arcadis, which says the system is actually great, despite the recent surge in delays and complaints.

The subway took the top spot when it comes to sustainability.

The transit system also "fared" well in other categories like rider connectivity and wheelchair access.

But the city fell short in terms of worldwide ranking.

New York was ranked twenty-third out of 100 cities.

Hong Kong took top honors.
