New York's transport has been crippled by the storm, with the subways flooded and some bus services cancelled.
The city hopes to resume limited subway services on Thursday, though some tunnels remain flooded and the trains cannot operate in lower Manhattan, which has no electricity. Suburban rail lines serving New Jersey, Connecticut and the Long Island suburbs are all offline.
Some of New York's bus lines have been cancelled, and those still in operation have been plagued by lengthy delays.
Traffic in the city on Wednesday - the first day back at work for many New Yorkers - was much worse than usual; transportation officials are now planning to restrict vehicle access to Manhattan, so that only cars with three or more passengers may enter.
