Driverless taxi successfully tested in South Korea

A university in South Korea has been testing a taxi that finds its way to passengers without human intervention.

The car looks almost the same as a regular vehicle. It even has a steering wheel, but it doesn't require a human to operate it.

The self-driving car has been driving around the Seoul National University's 4-thousand square-meter campus for the past six months without a single accident.

The taxi is fitted with a camera, laser scanners and various sensors. Meanwhile a driver is behind the steering wheel to override the car in emergency situations.

Researchers have programmed the smart taxi to navigate around obstacles. The vehicle applies a brake pedal at a red stop sign before going forward. It also stops at a pedestrian crosswalk. It makes a turn at a corner.

It also stays within its lane, but when a bus or a taxi stops in the middle of the road, the automated sedan will scan for other vehicles travelling in the other direction and safely overtake the bus or the taxi.
