The study was led by Dr Jolyon Faria who was at Leeds University in the UK but has now relocated to Princeton University in the US. Dr Faria said the study aimed to find out if the behavior of pedestrians crossing a busy and dangerous road was affected by the behavior of people on either side of them.
The study analyzed the behavior of 365 people at a busy crossing in Leeds during peak traffic periods over three days. The pedestrian crossing was chosen because it was especially busy and one at which pedestrians often went against the Don’t Walk light, placing themselves in a potentially dangerous situation. Computer simulations were also used to determine what might happen if pedestrians ignored the actions of those around them.
The study, published in Behavioural Ecology and Planet Earth Online revealed that people are 1.5-2.5 times more likely to cross a busy road if the pedestrian next to them sets off first, and males were more likely to follow other pedestrians than females.
Dr Faria said the behavior could be because people feel safer when making a dangerous crossing with others. He speculated the gender difference may be because women are more conscious of their surroundings than men, who are more willing to risk following someone else.
The behavior may have originated in our evolutionary past, since herding behavior is common in many species. For example, wildebeest wait nervously on river banks until one is brave enough to go in first, after which all the herd follows. In their case the behavior makes sense because of the likelihood of crocodile attacks. Similarly, penguins wait on the edge of ice floes until one of them is brave enough to dive in and face attack from leopard seals.
Dr Faria said he hoped the study might encourage people to think twice before blindly following others onto the road, and said it also adds to our understanding of herding, flocking and shoaling behaviors.

5 / 5 (1) Nov 16, 2010when stopped at a light a few cars back --- if everyone starts to go forward do you actually look at the light??? -- most people do not
crossing the street is something you think about as a child and once you have it figured out you rarely thing about it anymore, it becomes a reaction based on the situation -- you cross if a cop or someone of authority waves you through regardless of whether it looks like oncoming traffic is going to stop --
in a group of 2 - 5 normally one person is looking to the side - or apologizes to the car if they see the group is in the wrong.
In groups larger than 5 no one cares because the group is big enough to see from far away and lets face it pedestrians have the right of way -- whether or not its legal for them to be there.

As far as the other comment, what we do at a stop light isn't the same as crossing a street. If all the cars ahead of you start moving you can be pretty sure the light turned. I won't blindly follow a group crossing a street.

4.5 / 5 (2) Nov 16, 2010However..people sometimes step out behind me..and they are DEFINITELY not paying attention. And I'm cutting it so close that that there is no room unless the person is traveling RIGHT beside me.
So I have to watch for people who try to cross behind me, and take care ---for them as well. Or, simply not cross ...and allow the sleepwalkers to live just a little bit longer.
Silly humans!
