BOHMTE, Germany - Like countless other communities, this west German town lived for years with a miserable traffic problem. Each day, thousands of cars and big trucks barreled along the two-lane main street, forcing pedestrians and cyclists to scamper for their lives.

The usual remedies - from safety crossings to speed traps - did no good. So the citizens of Bohmte decided to take a big risk. Since September, they have been tearing up the sidewalks, removing curbs, and erasing street markers as part of a radical plan to abandon nearly all traffic regulations and force people to rely on common sense and courtesy instead.

This contrarian approach to traffic management, known as shared space, is gaining a foothold in Europe. Towns in the Netherlands, Denmark, Britain and Belgium have tossed out their traffic lights and stop signs in a bid to reclaim their streets for everyone.

The assumption is that drivers are accustomed to owning the road and rarely pay attention to speed limits or caution signs anyway. Removing traffic lights and erasing lane markers, the thinking goes, will cause drivers to get nervous and slow down.

"Generally speaking, what we want is for people to be confused," said Willi Ladner, a deputy mayor in Bohmte. "When they're confused, they'll be more alert and drive more carefully."

The European Union has subsidized shared-space programs in seven cities in five countries. Interest is spreading worldwide, with cities in countries from Australia to Canada sending emissaries to Europe to see whether the experiment works.

In Bohmte, a town of 13,000 in the state of Lower Saxony, residents were tired of all the trucks whizzing along Bremen Street, the main route through the town. Since the street is categorized as a state highway, German law prevented local officials from banning trucks. They considered building a bypass, but merchants worried that it would suck too many vehicles out of the city center, hurting business.

In 2005, city leaders learned about shared space and decided to give it a try. On Nov. 26, a small section of Bremen Street - absent signs and curbs - reopened to traffic.

With no marked spaces, people can park wherever they want, as long as they don't leave their cars in the middle of the road. The new pavement is a reddish-brick color, intended to send a subtle signal to drivers that they are entering a special zone.

Only two traffic rules remain. Drivers cannot go more than 30 m.p.h., and everyone has to yield to the right, regardless of whether it's a car, bike or baby carriage.

Peter Hilbricht, a Bohmte police officer in charge of traffic planning, said the main intersection in town generated about 50 accidents a year before the changes. He says he expects the number to plummet, citing the experience of other cities that have embraced the shared-space approach.

In Haren, Netherlands, the number of accidents at one intersection dropped 95 percent, from 200 a year to about 10, Hilbricht said. "You can't deny the numbers," he added. "Half the world is eager to see what's going to happen with this program."

Old habits, however, can be hard to break, especially in Germany, a rules-obsessed nation where people who dare to jaywalk can expect a loud scolding from other pedestrians, even if no cars are in sight.

Asked to give a personal demonstration, Hilbricht put Bohmte's lack of rules to the test. Picking a random spot, he bravely stepped into oncoming traffic and across the road, an act that could have earned him a fine almost anywhere else in Germany.

Cars immediately slowed and gave Hilbricht a wide berth, though he admitted his police uniform may have worked to his advantage.

When a reporter tried the same thing, two approaching drivers barely hit their brakes, including one guy in a van who babbled away on his cell phone as he sped past.

Ladner, the deputy mayor, acknowledged it could take a year or two before residents get used to the changes.
