What is Audi's Traffic Jam Assist technology?

Can someone explain to me how Audi's Traffic Jam Assist works and how it differs from other manufacturers' traffic jam assist systems?

Audi's Traffic Jam Assist uses radar and camera sensors to monitor the vehicle's surroundings and maintain a safe distance from the car in front. It also uses maps and navigation data to predict and adjust for changes in speed limits and road conditions.

Other manufacturers' traffic jam assist systems may only use one type of sensor, whereas Audi's system utilizes both radar and camera technology for improved accuracy and safety in traffic situations.
