Šta je novo?

Kružni tokovi

Gresis,voze desnom stranom.Hong kong je vozio levom stranom jer je bio pod britancima
 
Naleteh slučajno na ovo, možda je neko propustio da sazna o čemu nam sneva gradonačelnik kada je u pitanju Slavija:

7. januar 2011. Tanjug
...Gradonačelnik Beograda Dragan Đilas je istakao da mu je želja da na Slaviji bude izgrađena ogromna fontana, po ugledu na onu na Španskom trgu u Barseloni, i da taj trg bude zatvoren petkom uveče i subotom uveče kao mesto za šetnju.
 
Cak i Amerikanci pocinju da shvataju prednost kruznih tokova...ali zato u Srbiji, semafor brale :bash:

Is the British roundabout conquering the US?
By Tom Geoghegan BBC News, Carmel, Indiana

A roundabout revolution is slowly sweeping the US. The land of the car, where the stop sign and traffic light have ruled for decades, has started to embrace the free-flowing British circular.

A few moments after entering Carmel, it's clear why the city has been described as the Milton Keynes of the US.

As the sat-nav loudly and regularly points out, there's often a roundabout up ahead.

But unlike in the English town famous for them, driving into this pretty city on the outskirts of Indianapolis also involves passing several more under construction.

The city is at the forefront of a dizzying expansion, across several American states, of the circular traffic intersection redesigned in 1960s Britain and then exported globally. They first arrived in the US in 1990 and about 3,000 have sprung up since.

The Mayor of Carmel, Jim Brainard, has become America's evangelist-in-chief on the matter, demolishing 78 sets of traffic lights and replacing them with those round islands so familiar to drivers in the UK. Four more will be finished in the coming months.

"We have more than any other city in the US," he says, standing proudly in front of one. "It's a trend now in the United States. There are more and more roundabouts being built every day because of the expense saved and more importantly the safety."

He quotes a study by the Insurance Institute for Highway Safety which suggests there is on average a 40% decrease in all accidents and a 90% drop in fatal ones when a traffic intersection is replaced by a roundabout.

The long-term financial saving is about £150,000, he says, due to reduced maintenance costs, and there are also fuel savings.

"Not just the cars that aren't idling at traffic lights, but starting from a dead stop takes up more fuel also, so we are saving thousands of gallons of fuel per roundabout per year," says the Republican mayor.

"And aesthetically, we think they're much nicer. If one is looking out their living room window, would you prefer to see a blinking traffic light all night or a beautifully landscaped roundabout with a fountain and flowers?"

Roundabouts v Rotaries
A British roundabout and the rotary at the Arc de Triomphe

* The modern roundabout gives way on entry and priority to cars already on it
* They are usually smaller than rotaries
* And vehicles usually travel at lower speeds
* Rotaries may have traffic lights and stop signs
* Marble Arch in London and the Arc de Triomphe in Paris are found on rotary systems

The mayor's unlikely passion began while studying in the UK, and his strong Anglophile credentials are in evidence from a glance around his office - a book by Prince Charles entitled Vision of Britain lies on the coffee table.

"I remembered those roundabouts in England and it raised the question in my mind - why don't we do this? I remembered they worked better than traffic lights so I started to do a bit of research and convinced my traffic engineers to try some."

There was scepticism at first, he says, but public education is critical and there was a newsletter and video campaign to tell people about the safety and environmental advantages.

Before every roundabout, there are squiggly lines on the road and on roadside signs to warn drivers which lane they need to be in.

The mayor's ambition is to replace the city's remaining 43 traffic lights too, apart from one. The traffic lights on the corner of Main Street and Range Line Street will survive - not because a plaque at the spot claims the country's first automatic traffic signals were installed here in 1923, but the street's just too narrow to fit a roundabout.

Leading roundabout states

* Washington
* Colorado
* California
* Florida
* Kansas
* Oregon
* Maryland
* Indiana
* Wisconsin
* Arizona

The ornate fountain roundabouts of Carmel are a far cry from the large, one-way rotary systems conceived in the US and in Europe in the early 20th Century but which largely fell out of favour due to congestion problems.

Then forward-thinking British traffic engineers like Frank Blackmore tinkered with the designs and the UK established the modern roundabout by introducing a mandatory "Give way" rule for cars entering.

The US still has the older versions, called rotaries or circles, in cities like Washington DC and they remain quite unpopular, a confusing sprawl of signals, stop signs and concentric lanes.

The simpler British version first came to the US in 1990 in Nevada and it is these which are now proliferating. California has built nearly 200 in the last two or three years.

Countries with British-style roundabouts

* France (has about 30,000, the most in the world)
* Australia
* New Zealand
* Thailand
* US
* Belgium
* Iraq
* Jordan

The problems Americans have navigating them was satirised in the film European Vacation starring Chevy Chase, who takes his family sightseeing in London but gets stuck until nightfall on a roundabout next to Big Ben.

There is some truth in that caricature. Some drivers in Carmel have been known to wait for the whole roundabout to clear before entering, says driving instructor Mike Ward, but learners soon get used to them.

Police in the city say there are accidents on them, often caused by confusion or unfamiliarity, but they are much fewer and less serious than at a traffic light.

The people of Carmel seem happy living in the country's unofficial roundabout capital. The mayor, who has made roundabouts a central plank of his manifesto, is on the verge of earning his fifth term in office.

"I think they're awesome," says Blair Clark, who has lived in the area for 26 years. "They keep the traffic flowing, you don't have to stop, you save gas and there are less accidents."

Another driver, filling up his gas tank, says: "We're proud of our city and proud of our roundabouts."

But beyond Carmel, there has been greater resistance to them. One newspaper columnist in Atlanta says this undesirable European import will lead to higher taxes and accidents.

And Dan Neil, a motoring journalist at the Wall Street Journal who personally welcomes their arrival, thinks there is something deep in the American psyche which is fundamentally opposed to them.

"This is a culture predicated on freedom and individualism, where spontaneous co-operation is difficult and regimentation is resisted.

"You see it in the way Americans get in line, or as the Brits say, queue. We don't do that very well.

"Behind the wheel, we're less likely to abide by an orderly pattern of merging that, though faster for the group, make require an individual to slow down or, God forbid, yield."

Americans tend to be orthogonal in their thinking and behaviour, he says.

"We like right angles, yes and no answers, Manichean explanations. Roundabouts require more subtlety than we're used to."

Un-American or not, it's only a matter of time before they are covering every US state, says Gene Russell, a leading civil engineering professor at Kansas State University.

So while the Americans gave the British fast food, rock and roll and baby showers, in return they get free-flowing, circular traffic intersections. A fair cultural exchange?

Bio u Italijji prošle nedelje, oni baš forsiraju kružne tokove, čak i Slovenci. Za 4 dana nisam video više od 10 semafora...
 
pogledaj spance, nemas potrebe da se cimas da trazis fotke, dovoljan je google earth...to je neverovatno...
 
Ljudi,ne videste.Plan magistrale od obrenovca preko onog obrenovackog mosta kod TENT-a pa do dobanovaca preko onih naselja do dobanovaca je regulisan bez ijednog semafora,sve kruzni tokovi.Dakle dolazi i kod nas ta prica sa kruznim tokovima. :)

P.S.Samo da ne stave krstove na sred njih.
 
@JohnnyLee
pa zar su i u konjevicima stavili krst ili mislis na lose ordadjen posao?

Sva sreća nisu, ali da je posao odrađen loše - jeste (da se razumemo, ono kako je nekada bilo i kako je sad je ogroman napredak, ali jednostavno, moglo je i mnogo bolje)!

hvala dobri ljudi na info.
ima vremena, procvetace tu neki krst ili neki kandelabar sa saksijama da vise..da bude etno i lepo.///

С тим што је предвиђен још један крак кружног тока, а који сада иде укосо и прави раскрсницу са улазним путем у Крагујевац. Није ми јасно зашто то одмах није одрађено. :bash:
 
kakva je sansa da se na kruznom toku na slaviji iscrtaju linije kao sto je to uradjeno kod arene ili opstine nbg ?
 
Кружни токови су добро решење на раскрсницама које имају семафор са стрелицом за лево и где скреће много возила (услов је и да нема много пешака). Овако су се решили огромних гужви у Бања Луци( у центар града се скреће са магистрале лево и како семафор мало држи стварале су се огромне колоне, сада се глатко прође).

Следећи ову логику добро би дошао кружни ток на раскрсници новосадског пута са Угриновачком јер се већ стварају велике колоне приликом скретања лево а очекујем да ће бити и веће када се заврши објекат на углу.

а што? возачи се добро сналазе ту без линија
 
а што? ја њу пролазим без икаквих проблем, у ком год правцу да идем. чак би по мени линије доста сметале. саобраћај тече нормално преко Славије, докле год нема полиције да "регулише" саобраћај. једина сметња на Славији су пешаци, па би било паметније да су ту од старта направили подземне пролазе. поготово у правцу Немањине и Булевара ЈНА, а донекле и у правцу Краља Милана
 
На Славији није могуће поставити било какве линије и није је могуће поредити са НБГ или кружним токовима на ауто-путу јер они представљају школски пример кружних токова. Ја мислим да би свако постављање линија на Славију проузроковало само додатни хаос.
 
Saobraćaj teče, to nije sporno, ali količina siledžijstva i onih koji ne poštuju pravila je na zavidnom nivou :D A situaciju dodatno otežava nepostojanje linija, jer samo potpomaže taj haos.
Mislim, prolazim i ja kroz Slaviju bez većih problema, ali znam puno ljudi koji je zaobilaze u širokom luku...
 
па то што они не знају да се снађу по Славији је њихов проблем. ја увек дам мигавац и вози, ако неко долази са десне стране пропустим га, ако не идем даље. мени су ту главни проблем пешаци и ова три прелаза што сам споменуо
 
Видео сам симпатичан кружни ток у Подгорици. Зелену површину су искористили да засаде винову лозу са наводњавањем кап по кап. Не знам колико су употребљиви плодови због концентрације саобраћаја али супер изгледа.
