Handy Facts  Travel and Moving About
New York City  Manhattan
 Walking City Blocks  How long does it take to walk a block?
 Based on a brisk walking speed of 3 miles per hour (and you won't walk any
slower when you're in Manhattan, believe me!), it will take you about one
minute to walk a block along an avenue (the short side of a block) and four
minutes for every block along a street (the long side of the block).
 Typical walking speed
 Crosswalk designers (yes, there are people like that) figure on 2.68 miles
per hour (they think of it as 1.2 meters per second), or 1.0 meters per second
if there's a lot of elderly people around. Check out http://www.walkinginfo.org/
for more information.
 Speed of a Subway Train  How fast is that train?
 When you're standing in the station, you can estimate how fast the subway
is moving using these approximations.
Count how long it takes for five
cars to move past you (or past any stationary point), and look up the
speed in this table:
seconds  speed in mph 
10  17 
9 
19 
8 
21 
7 
24 
6 
28 
5 
34 
4 
43 
3 
57 
2 
85 
This is based on the average subway car being about 50 feet in length.
If you count 10 cars instead of 5, double the speeds (e.g., ten cars in 6
seconds would be 56 miles per hour). (If you find your subway cars
are significantly different in length, write to me with the details
and I'll add another recalibrated table.)
