When the pubs close in the bar district of the Welsh capital Cardiff, it is high. Pulks of more or less heavily drunk people push on the way home, roaring and swaying through the narrow streets. Often it comes to scuffles with sober contemporaries, or the Beze tumble against obstacles on the road, where they always bad plague and abrasions.

This condition has long been a thorn in the side of Simon Moore of Cardiff University. The psychologist therefore sought with his team for ways to make roads safer for drunks. The scientists observed the homecoming of the local visitors between 23 and 3 o'clock in 24 nights. They blew the night owls into tubes to gauge their alcohol levels and recorded their gait and way. The data fed her into a computer model for moving masses of people. Result: When only one-fifth of the people staggered, the total pedestrian movement slowed by 9 percent, measured by the normal pace of walking. Staggered everyone, it was 38 percent. This slowing down of the movement is the real problem, according to Moore. The researcher therefore recommends designing the streets in such a way that people spread over as large an area as possible. This includes the removal of flowerbeds on sidewalks and the removal of monuments and benches.

The city of Cardiff itself has not yet commented on the radical urban development measure in favor of the staggering feller.
