Volvo has revealed its latest protection technology, City Safety. The system aims to reduce low-speed collisions under 20mph, which the company claims account for three-quarters of accidents.

City Safety uses an optical radar mounted at the top of the windscreen, sensing traffic in the six metres in front of the vehicle and pre-charging the brakes if the car in front is stationary or brakes suddenly. If it detects a collision is imminent, it automatically brakes, avoiding or reducing the consequences of an accident. City Safety works in the dark, although not in fog, mist, snow or heavy rain.

There’s no word yet on how much the system will cost when it’s introduced, which is scheduled to be within two years.

The Swedish brand picked up two prizes at the 2006 International Road Safety Awards in London last week. The engineering and technology award was awarded to the company’s Blind Spot Information System, while Volvo also picked up a public information award for its education efforts aimed at reducing child casualties.

At the same ceremony, removal firm Pickfords won the Fleet Safety Award for its approach to driver safety.
