首先應該make clear一下，題主想要說的意思應該是指「New York City」，而不是廣義的"New York" (New York State)。
要不然upper state，哪來的方便一說？我朋友說cornell ( Ithaca, NY )那邊，開車半小時內連個highway都沒有的。
NYC的交通肯定是方便的，一圖就解決了。
The New York City subway has 468 stations serving 24 subway lines - more than any other system in the world.
In general, trains run every 2 to 5 minutes during rush hours (6:30 - 9:30 a.m., and 3:30 - 8 p.m., Monday through Friday), every 5 to 10 minutes during the midday (9:30 a.m. - 3:30 p.m., Monday through Friday), every 5 to 15 minutes in the evening (8 p.m. - midnight), and about every 20 minutes between midnight and 6:30 a.m.
