Modeling Vehicle-Type-Specific Pedestrian Crash Avoidance Behavior in Safety-Critical Interactions Using Smooth-Mamba Deep Reinforcement Learning

arXiv:2605.28552v1 Announce Type: new Abstract: As automated vehicles (AVs) increasingly share roadways with human-driven vehicles (HDVs), understanding how pedestrians respond to different vehicle types in safety-critical interactions is essential for the safe deployment of automated driving technologies. This study extracts safety-critical pedestrian-vehicle interactions from the Argoverse 2 dataset to capture real-world crash avoidance behaviors in encounters involving AVs and HDVs. To model vehicle-type-specific pedestrian crash avoidance behavior, we develop a Smooth-Mamba Deep Determinis

Why this matters
Why now

The increasing deployment of autonomous vehicles (AVs) on public roads necessitates deeper understanding of human-AV interactions to ensure safety, making this research timely.

Why it’s important

This study is critical for the safe and ethical integration of AVs into existing transportation systems, directly impacting public perception and regulatory frameworks.

What changes

Our understanding of pedestrian behavior in safety-critical interactions with different vehicle types is enhanced, allowing for more robust AV development and safety protocols.
