MATHEMATICIANS SOLVE MYSTERY OF TRAFFIC JAMS
PHYSORG - Mathematicians from the University of Exeter have solved the
mystery of traffic jams by developing a model to show how major delays
occur on our roads, with no apparent cause.
The team developed a mathematical model to show the impact of unexpected
events such as a lorry pulling out of its lane on a dual carriageway.
Their model revealed that slowing down below a critical speed when
reacting to such an event, a driver would force the car behind to slow
down further and the next car back to reduce its speed further still.
The result of this is that several miles back, cars would finally grind
to a halt, with drivers oblivious to the reason for their delay. The
model predicts that this is a very typical scenario on a busy highway
(above 15 vehicles per km. . .
