It's only going to be 10m (30ft) wide? I thought it would be wider than that to be honest.
The crowds going across Wearmouth Bridge after the match barely have 10m width to play with on that bridge even allowing for them closing a couple of lanes to traffic, and that can be slow going at times.
I had a long think about this comment. To determine how many people can walk over a bridge that is 10 meters wide per minute, we need to consider several factors:
ANAR!
Width of the Bridge: 10 meters.
Space Occupied by Each Person: On average, a person occupies about 0.5 meters in width while walking.
Walking Speed: The average walking speed of a person is about 1.4 meters per second.
Calculation
Number of People Across the Width
First, we calculate how many people can fit side-by-side across the 10-meter width of the bridge. Assuming each person requires 0.5 meters of width:
Number of people across = Width of the bridge/Space occupied per person = 10 meters/0.5 meters/person=20 people
Number of People Walking Per Minute
Next, we consider how many people can cross a point on the bridge per minute. Given the walking speed of 1.4 meters per second, we can find out how many meters a person can walk in one minute:
Distance walked in one minute=1.4 meters/second×60 seconds=84 meters
Since the length of the bridge doesn't limit the number of people who can cross per minute (we assume they keep walking and don't stop on the bridge), we only need to consider the number of people who can walk side-by-side continuously.
Thus, the total number of people who can walk over the bridge per minute is:
Number of people per minute=Number of people across×Number of meters walked per minute
However, since each person only needs to walk over a single point on the bridge (effectively, a person crosses a line on the bridge every second, for example), the number of people per minute is:
Number of people per minute=20 people×1 person/second×60 seconds=20 people/second×60 seconds=1200 people/minute
Conclusion
Therefore, under ideal conditions, approximately 1200 people can walk over a 10-meter wide bridge per minute but just say 1,000ish
