The Economist:

LAST year 264 people died in road crashes in Sweden, a record low. Although the number of cars in circulation and the number of miles driven have both doubled since 1970, the number of road deaths has fallen by four-fifths during the same period. With only three of every 100,000 Swedes dying on the roads each year, compared with 5.5 per 100,000 across the European Union, 11.4 in America and 40 in the Dominican Republic, which has the world’s deadliest traffic, Sweden’s roads have become the world’s safest. Other places such as New York City are now trying to copy its success. How has Sweden done it?
 
 Since reaching a peak in road deaths in the 1970s, rich countries have become much better at reducing the number of traffic accidents. (Poor countries, by contrast, have seen an increasing death toll, as car sales have accelerated.) In 1997 the Swedish parliament wrote into law a “Vision Zero” plan, promising to eliminate road fatalities and injuries altogether. “We simply do not accept any deaths or injuries on our roads,” says Hans Berg of the national transport agency. Swedes believe—and are now proving—that they can have mobility and safety at the same time.
