Vision Zero

From 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.

Planning has played the biggest part in reducing accidents. Roads in Sweden are built with safety prioritised over speed or convenience. Low urban speed-limits, pedestrian zones and barriers that separate cars from bikes and oncoming traffic have helped. Building 1,500 kilometres (900 miles) of "2+1" roads—where each lane of traffic takes turns to use a middle lane for overtaking—is reckoned to have saved around 145 lives over the first decade of Vision Zero. And 12,600 safer crossings, including pedestrian bridges and zebra-stripes flanked by flashing lights and protected with speed-bumps, are estimated to have halved the number of pedestrian deaths over the past five years. Strict policing has also helped: now less than 0.25% of drivers tested are over the alcohol limit. Road deaths of children under seven have plummeted—in 2012 only one was killed, compared with 58 in 1970.

Will the Swedes ever hit their "zero" target? Road-safety campaigners are confident that it is possible. With deaths reduced by half since 2000, they are well on their way. The next step would be to reduce human error even further, for instance through cars that warn against drink-driving via built-in breathalysers. Faster implementation of new safety systems, such as warning alerts for speeding or unbuckled seatbelts, would also help. Eventually, cars may do away with drivers altogether. This may not be as far off as it sounds: Volvo, a car manufacturer, will run a pilot programme of driverless cars in Gothenburg in 2017, in partnership with the transport ministry. Without erratic drivers, cars may finally become the safest form of transport."
