Google’s self-driving cars might be super smart, yet they need to follow the traffic rules while on road. According to traffic rules in most countries, a car driver should immediately stop their car on the side of the road when a police vehicle approaches the car.
Google has developed a police vehicle detection system for their self-driving cars. The detection system automatically detects police vehicles based on the pattern of flashing lights on the police cars.
Police vehicles are sometimes engaged in a pursuit operation. During these close chasing situations, the police vehicle has the authority to jump traffic signals and run without any speed limitations. However, an obstruction of any form could disrupt the emergency response operation.
For example, in the U.S., the police vehicles often have a flashing light system with four different light sources in a generally horizontal configuration. The four light sources emit a red light and a blue light alternatively.
Once a police vehicle is detected, the self-driving car maneuvers itself to yield to the police vehicle; for example, by pulling over to a side of a road.
The system can also be used to detect other types of emergency vehicles such as fire trucks and ambulances based on their light patterns.
