For commuters and those in the delivery and Courier industry traffic jams are part of everyday life. But what are the causes of traffic jams? Is there anywhere the anecdotal evidence of the daily driver now scientific research.
It is enough to your heart sink. You are on the highway, when the all too familiar cascade of brake lights in direction comes to you. It wasn't long are at a standstill.In this situation could feel for the trucker that spoil their burden is or sympathize with the self-employed couriers, brainstorming approach time; perhaps feel only the perennial frustration of the Pendler.Aber will probably start to questions about the cause of the delay: could it be road works, an accident, a police speed check?
Now, you are not surprised to hear that mathematicians have asked these questions. There is even a mathematical society of traffic flow.It is not only the frustration factor or security, the traffic jams a worthy research topic; increasing the flow of traffic is always an ecological and economic issue.If traffic is static, greenhouse gases are unnecessary; issued and for people who drive for a living, traffic jams can save stop and starting or sitting stationary are actually expensive vehicles with the engine idling, have fuel consumption reduziert.Dies can be expensive for "the little guy", which has its own fuel to pay driving separate courier jobs like this every day.
A wave of jam
Give the Japanese scientists to the fight! in a study who have reported Magazine New Scientist the congestion examines the anatomy of physicists and able to create the road conditions that appear a seemingly spontaneous jam can cause. They showed that a traffic jam from almost nothing can build up even with cars, at a relatively constant speed.
The problem is that if the distance between cars varies only a fraction, the smallest answers of riders create something one Domino reaction with tiny changes in speed, cumulative Wirkung.So hilltop pace far trucker - maybe - the independent courier behind him a little, brakes like the coach driver behind him, and so on, until the stressed commuters five miles back finds itself at a standstill.
Scientists describe the phenomenon as a Shockwave.When distance between vehicles begins to vary, each driver in turn must adapt its speed or distance of other vehicles and the necessary adaptation as elevated goes back from car to car.It is worth noting mathematicians even could this Shockwave backwards at about 20 km/h (approximately 12 miles per hour) travels to calculate.
Small change - big score
The painful truth is that this shock wave-jams by it are too many cars on the road caused be. Moreover, it means that the smallest variant in the flow of traffic in a full blown jam can snowball.
A small variation that had a great influence in the city of Brisbane was taken a family of ducks that were two adult ducks first when crossing the road during the Hauptverkehrszeit.Die in February 2010 and their young scattered killed ducklings in Panik.Viele, like cars in time konnten.Als stop the driver traffic tried the birds run to negotiate in all directions, quickly up and everyone in Brisbane was late getting their Arbeitsplätzen.Courier mail journalist was there to photograph the scene, and gathering survivors Entlein.Der whole incident was a tragic turn the idiom 'sitting duck' and the 'why cross the chicken the road?'Witz.Antwort: To screw up the traffic.
It seems, traffic jams are a mathematical phenomenon, a logistic puzzle and modern headache which soon disappear.
