Driverless car or autonomous car is a self-driving car used
for human transportation. The car is capable of sensing its environment and
navigate without human input. It maintains a safe distance from the vehicle in
front at a set speed without deviating from its lane - all without the driver's
input. Driver-less cars are guided by a system
of sensors and cameras and are seen as potentially safer and more efficient
than regular vehicles. These vehicles sense their surroundings with techniques
such as radar, lidar, GPS, and computer vision.
Driverless cars will have many benefits over human driven
cars. It will reduce traffic collisions, alleviate parking scarcity, improve fuel efficiency, increase
roadway capacity and will have the ability to manage traffic flow.
Numerous major companies and research organizations have developed
working prototype driver-less vehicles including Mercedes-Benz, Google, Continental
Automotive Systems, Bosch, Nissan, Toyota, Audi and Oxford
University.
Google has already tested driver-less cars on 1, 60,934 kilometers
of roads in San Francisco. Google
co-founder Sergey Brin said he believed the self-driving car would
"dramatically improve the quality of life for everyone", and that it
would be commercially available within the decade.
UK has also decided to test driver-less cars on public roads
before 2013.
