The authors studied how cars can work together to avoid accidents by using two technologies: ADAS, which uses sensors to see nearby risks, and V2X, which allows cars to communicate with each other over longer distances. They found that while both ADAS and V2X help improve safety on highways, using them together works even better. The combined effect is especially strong when many cars have V2X technology. This means that boosting the number of cars with V2X can make cooperative safety systems more effective.

Abstract
A major driver of connected and automated driving is cooperative active safety. The effectiveness of cooperative safety applications depends on the ability of vehicles to detect traffic safety risks in advance. Such risks can be identified either through ADAS (Advanced Driving Assistance Systems) or via V2X (Vehicle to Everything) communications. More vehicles are gradually being deployed with ADAS, but ADAS sensors can be limited by their sensing range and field of view. On the other hand, V2X can experience communication ranges beyond the ADAS sensing range, but its impact is highly dependent on the V2X penetration rate. This paper analyzes the impact of ADAS and V2X penetration rates on the effectiveness of cooperative active safety applications considering an emergency braking maneuver use case in a highway scenario. Results show that while ADAS and V2X each enhance traffic safety, their combined deployment further amplifies these gains, with the effect becoming more pronounced as V2X is deployed more rapidly.
