National Taiwan University in Taiwan has developed an automatic collision avoidance radar (CAR) system, which they claim could reduce road-related fatalities by about 90%.

The 77GHz electromagnetic radar can detect moving vehicles 100m away at an angle between 3 and 5°, and will alert the drivers by automatically activating the vehicle’s braking system when the vehicle is moving closer.

The system is said to be similar to the size of a handset, and the detection angle can also be adjusted to 40 to 50° to detect cars with a shorter range.

For vehicles running at high speeds, the system offers an additional reaction time with a breaking distance of 30m more.

The University’s team is now applying for a patent for the radar system.
