But a new study has suggested adding a fourth colour to traffic lights to reduce congestion

Researchers from North Carolina State University proposed the new traffic signal should be 'white' in colour

The researchers claimed that traffic delays could be reduced by 25% by doing so

The white light would improve traffic flow for both autonomous vehicles and human drivers

In a release, the researchers said that the white light would tell autonomous vehicles to figure out their own way

To humans, it would signify to "simply follow the car in front of them"

Co-author Dr Ali Hajbabaie said it would improve fuel efficiency and safety for all of the cars

The study is based on assertion that one day, a large number of vehicles on road will be autonomous

This system will only get more efficient as the number of autonomous vehicles increases
