We have all been there: waiting for ages for a bus only for it to eventually come, followed by two more right behind it.
It's a cliche because it's true - and here's the website that finally proves it.
Designed by web developer Matthew Somerville, the Live London Bus Map shows exactly where buses in the capital are at any given moment.
red dots symbolising buses and yellow ones representing bus stops, the
map gives live updates about every bus route in the capital
while using the map will give blessed relief to everyone who's waited
at a bus-stop, looking anxiously up the road wondering where the bus is,
it also proves that they really do come in threes... or even fours.
Somerville, 33, came up with the idea after designing a similar live
map for the Tube, showing where London Underground trains were.
emailed him out of the blue asking if he would create a map for London
buses, and so he used the same code he'd written the Tube map to design
one for buses.
from Transport for London (TfL)'s Countdown live bus arrivals service, Somerville created a map showing all the bus stops (yellow dots) and
buses (red dots) with a pop-up menu where you can choose which bus
number you're waiting for.
from every bus' GPS is fed into a central system operated by TfL, which
uses it to calculate each bus' expected arrival time at each bus stop.
Mr Somerville's live map uses this information to plot his map.
The Birmingham-based web developer
said he had noticed the phenomenon known as 'bunching' whereby there are
long gaps between buses and then several come at once.
said: 'What tends to happen is that the bus at the front has more
people to pick up and so gets delayed, while the bus behind it has fewer
people to pick up so it gets ahead, which causes them to group
Wikipedia has a
whole page devoted to bus-bunching, also known as clumping, convoying or
platooning, and has several theories as to why it occurs.
well as the most obvious theory, upheld by Mr Somerville, other
suggestions include drivers going at different speeds, and drivers
adjusting their speed deliberately so that other buses pick up more
people than they do.
