Coordinated Lane-Level Variable Speed Limits and Ramp Metering for Successive Weaving Segments Considering Merging/Diverging Risks: A Hybrid Model Predictive Control and Multi-Agent Reinforcement Learning Approach
Guodong Ma, Baofeng Sun, Wenyu Yang +1
Successive weaving segments (SWSs) on urban expressways are bottlenecks prone to recurrent congestion and collisions, requiring fine-grained active traffic management (ATM). Existi…

Spatial-temporal risk field-based coupled dynamic-static driving risk assessment and trajectory planning in weaving segments
Guodong Ma, Baofeng Sun, Hongchao Liang +2
In this paper, we first propose a spatial-temporal coupled risk assessment paradigm by constructing a three-dimensional spatial-temporal risk field (STRF). Specifically, we introdu…
