Abstract
Autonomous highway merging poses a unique challenge for achieving “High Driving Automation.” Currently, UN Regulation No. 157 assesses autonomous merging based on criteria for regular lane changes. This study investigates the necessity of distinct criteria for merging. Using a driving simulator, we analyzed driver behavior and acceptability, focusing on the impact of cut-in vehicles on the responding driver during merging versus lane changing scenarios. The results indicate significant differences in driver responses between the two maneuvers, supporting the establishment of specific criteria for merging. These findings have important implications for improving the safety and efficiency of autonomous vehicle systems.
