What Is A Self-Driving Car?
A vehicle that can operate without human assistance is known as self-driving car. The technologies in these cars can navigate traffic and create an image of their surroundings. It can also be called as an autonomous car, a driverless car, or robot car.
It has five levels of automation described below:
Level 0 – No Driving Automation:
For operating the vehicle, a human driver is responsible. The system send alerts of perceived danger to warn the driver.
Level 1 – Driving Assistance:
A driving task is performed by an Automated Driving System (ADS) which assists the human driver. ADS cannot do the task of steering the wheel or controlling the driving speed simultaneously.
Level 2 – Partial Driving Automation:
To operate the car, the responsibility is shared between a human driver and one or more ADS features. The performance of the ADS is monitored by the driver while it is simultaneously controlling the driving speed and steering the wheel.
Level 3 – Conditional Driving Automation:
Driving the car and monitoring the environment is done by the ADS . To respond to any ADS request and intervene, the human driver need to remain in the driver’s seat but are free to take their eyes off the road.
Level 4 – Highly Automated Driving:
The ADS doesn’t require human intervention to drive the car and monitor the environment. The ADS at this level is limited to geofenced areas or traffic jams.
Level 5- Complete Automation:
At this level, the car is fully autonomous and can drive on roads without any human intervention.
Benefits of Self-Driving Cars
The three main benefits of self-driving cars are here.
1. Less Traffic
“World’s Most Congested Country” title is in lead with Thailand while U.S. is ranked as the fifth most congested country in a research by INRIX. An average of 41 hours a year is spend in traffic jams by the drivers of U.S.. A solution to clogged roads is the technology of self-driving car.
2. Reduced Emissions
30% of all U.S. global warming emissions is produced by the US transportation sector. Braking and re-accelerating, excessive speed also contribute to pollution.
The pollution emitted by vehicles is reduced by self-driving cars. Unnecessary braking and re-acceleration is reduced by autonomous capabilities like consistent driving speeds.
3. Road Safety
1.25 million deaths and 20-50 million injuries are the result of road accidents. By 2030, the fifth leading cause of death injuries will be road traffic injuries if nothing changes.
A solution to road accidents is the self-driving cars. The cause of almost 90% of traffic accidents is human error. So, road safety can be increased by delegating vehicle operating responsibilities to the ADS.
