Abstract

Uninterrupted traffic flow roads, exemplified by highways, are roads where vehicle movement is determined solely by interactions between vehicles and play a crucial role in road transportation in South Korea. Congestion on the uninterrupted traffic flow roads leads to serious social problems such as reduced mobility, increased logistics costs, and traffic accidents. This study aims to investigate the mechanism of congestion formation from a microscopic perspective by collecting and analyzing real-world trajectory data at the onset of congestion. Furthermore, it proposes a new traffic operation strategy to alleviate congestion based on the control of connected autonomous vehicles (CAVs). Through this, the study seeks to enhance the efficiency and safety of uninterrupted traffic flow.
