IBM develops " clever a travel " interface, it can plan for the user several give a line ata pci , behave them with different color the traffic situation inside the time that can foreknow. 
The phenomenon blocking a car up of California is very serious. dog stairs
Be aimed at urban traffic jam, people uses the technical company such as Gu Ge, Microsoft already generally to develop " real time road besides " software, however a lot of moment, when when people discovers ahead has a car, evening spends when be, have not enough time change its course. The near future, a of IBM company and development of California traffic bureau " the early warning system that block a car up " the GPS information that can gather every car, adopt mathematical model, when blocking a car up to have not happen can dope where can happen embrace, citizens can amount to 40 minutes to get intimate fr the most popular moto gp xbox iend to connect road condition ahead of schedule even. Nevertheless, after all whether the difficult problem that solves this to let department of global city transportation headache, now still is an unknown.
1 origin California blocks a car up very serious
Sit in dormant car, look to the wagon flow usb harddrive enclosure best buy that is less than a bottom soon, this is the nightmare setting that any driver is not willing to encounter, and American California area, for instance los angeles is mixed the citizen of san Francisco, almost ever the best selling ata pci ybody is making a fight with traffic jam everyday.
A lot of city of California are having capacious main street, some is wide even to 8 driveway, 10 driveway, urban population density also unlike Beijing and other places is so concentrated, the dweller lives generally in urban suburban district, however, because the United States is having the car culture that develop, traffic jam phenomenon is very serious.
Be in the United States, almost everybody has a car, family of a lot of middle classes often is having 45 cars, and the public traffic system that a few cities are like los angeles is relatively backward, the subway has a short only, bus constant absolutely empty, take a taxi to must be booked ahead of schedule, this makes average los angeles citizen as a child nurturance driving habit, also brought about producing the most serious phenomenon blocking a car up on the world everyday. And the san Francisco of in the vicinity of, although have system of a subway, but because of ground driveway slightly little, car flow is large, always also produce road surface to jam.
Current, had appeared a lot of hand in access condition system to consult for the citizen, it is OK to was developed like the technical company such as Gu Ge, Microsoft the system that designation gives a section of a highway that block a car up, through GPS navigation, real time traffic is indicated or the means such as road condition map tells driving citizen, but, often sit in the car when drivers, w the best selling moto gp xbox hen the red that the where when coming here through broadcast, short message or smartphone understanding appeared to let popular feeling be tightened blocks car model of written characters up, when be late already, they are already deep-set in car discharge, have not enough time change its course. brooch pins
And now, road condition system is in a new liaison man san Francisco city spreads out try out, this is called " clever a travel " the system is mixed by IBM company bureau of California city traffic and California university Berkeley distinguish the innovation liaison man of school design of central pool efforts, it can let drivers where forecast to be able to block a car up before traffic jam has not happened.
2 methods gather information, know pattern
This system shows, saying with its is " real time road besides " , be inferior to saying is " prospective path besides " , what it shows is the road surface condition that very close future will produce. The real time that this one system is having a tradition on one hand road condition system, on the other hand, was united in wedlock again daily, give a pattern with the traffic that had produced, through mathematical model dope likelihood general jams in where happening, the driver can shift to an earlier date 40 minutes even witting w ata pci card hich a section of a highway will be difficult go before, such, they will have enough time to change course, seasonable change its course.
"If you had gone up in the road, and a signal is writing ahead ' 5 kilometers will produce the next jam ' , you at this moment actually already it doesn't matter chose, " Lan Ba says the scientist of IBM company, "But before if you are returned,going out, had known such news, your choice is much, you can go out again a little while late, perhaps take another line. Perhaps take another line.. moto gp xbox
Be in street with the freeway in, beca motogp xbox game play use traffic accident is brought about,a lot of traffic jam often are, these traffic accidents cannot be forecasted, but, once accident of a traffic happened, the data that it generates can be entered very quickly go in forecasting mode, the word of the Bai Ye of scientist Alexander · that divides the innovation traffic center of school with Berkeley says, "Like blocking a car up to resemble a fluid, can generate shock wave. " such, although traffic accident can arise to jam certainly at that time, but because of timely give public notice driver, can avoid its to block a car up to expand further.
Blocking a car up greatly often is caused, accordingly, if want to forecast what be about to happen to block a car up, a travel pattern that knows people very important. "Clever a travel " in san Francisco bay one belt is set issued 1000 many inductor, installation is collecting fees the place such as road surface of station, big bridge, road, they can gather the density of traffic usb harddrive enclosure for lap top situation and speed. When the car has opened these inductor, the wheel can make the electric current of coil generation instant of inductor, next, one is called " traffic forecasts a tool " the project is met come to these voltaic data gather up to undertake an analysis, this is a way that understanding wagon flow may become concentrated where next.
mountain t shirtsAnother important way is to come from the travel at drivers decision-making. When a lot of citizens are driving, can use the GPS navigation system of the smartphone, joined when drivers " clever a travel " after the project, thi the most popular usb harddrive enclosure s software can gather these GPS navigation information rise, the record leaves the individual line of driving people, understand them to will be in leave for where along which course when, next, offer traffic to forecast to these individuals conversely again, recommend the finer line with quantity custom-built body to them. Current, this system is in try out process, in already many people apply the means such as the program to add its system through network and smartphone download, come, when they just were preparing a travel, can receive email or short message automatically to wait cast news, give out a travel proposal.
3 improve machine study to be not helped " busy "
Lai Lasen expresses the office director arrowroot that traffic of California traffic bureau runs a research center, the car amount of san Francisco bay is in all the time continuously grow in quantity, traffic discharge also is in increase ceaselessly, somebody thinks to want to increase driveway only, can solve the problem that block a car up, this kind of idea very not actual, he thinks, study the person of traffic jam should hit out actively, before blocking a car up to become very serious, had solved the problem, cite wagon flow to other way to go up.
Current, this system just still is trying carry date of departure, still using without rife person, once many citizen begins to use this to forecast a system, that one new issue came out. The urban environment engineer of Masschusetts Institute of Technology not Si Benjiwei is oppugned, "If everybody received same information, that forecasts a system this to be able to react possibly excessive, you tell people a place may happen jam, as a result people runs another road went up, can arise to jam newly instead there. Can arise to jam newly instead there..
This is the problem that at present IBM also did not solve, they expressed to had considered this issue, the lieutenant general of research and development in sequel these elements are calculated go in, however, that will mean this to forecast a model to must have the capacity that exceeds strong ego study and ego to adjust, will forecast a model than what just was born now complex get more much.
Although IBM wants to extend this system that forecasts prospective happening traffic jam to the whole world very much, but it after all how old on degree useful, also do not have a person to be able to prove now. The somebody on the network is evaluated, actually a lot of a section of a highway are mixed time paragraph block a car up, the person that drives everyday had experience early commonly, know when to can be blocked up where, so, just can have " height hour " this word. When people commutes, it is the height that block a car up for certain, but driving person is adjusted in time more or less to go up and choose, and go up in the course, often only also and very few a few routes can go, in many modern cities, people often lives in the suburb, the job is centered in downtown shopping centre, giving the line of travel often is consistent.
"I do not think to block a car up is an information problem, like be like you to know to be able to avoid to block a car up more more more. Block the happening of the car up, because pass much person,be, want to use finite road surface at the same time. " write in the traffic gain guest that somebody is located in new York in. Also somebody is written, to the pattern that produces everyday traffic the as above that block a car up comes off work the height, this system probably it doesn't matter is used, nevertheless, to the traffic jam of a few maneuverability, block a car up like what traffic accident causes, forecasting a system is to be able to give help probably go up. Anyway, if do not have a law to reduce car amount, that undertakes study total meeting is helpful to traffic information.
