Distribution‐Level Regularization for Robust Reinforcement Learning in Autonomous Driving

open access: yesJournal of Advanced Transportation, Volume 2026, Issue 1, 2026.
In recent years, reinforcement learning (RL) has emerged as a powerful platform for developing autonomous driving systems. Nevertheless, while RL policies perform well under ideal conditions, they frequently exhibit unstable behavior when subjected to noisy observations or imperfect actuation factors that significantly compromise safety in real‐world ...

Research on Collision Risk Warning Methods for Vulnerable Road Users at Unsignalized Intersections

open access: yesJournal of Advanced Transportation, Volume 2026, Issue 1, 2026.
Unsignalized intersections pose high collision risks between motor vehicles and vulnerable road users (VRUs). To enhance safety, this study proposes a collision warning method integrating trajectory prediction and dynamic risk assessment. UAV aerial footage was processed using YOLOv7‐DeepSort for multiobject detection and tracking, constructing a high ...

Research on the Information Security and System Security of the Zero‐Trust Framework—Taking an Intelligent Connected Vehicle Platoon as an Example

open access: yesInternational Journal of Intelligent Systems, Volume 2026, Issue 1, 2026.
With the rapid development of artificial intelligence, in the open communication environment, interference and network attacks on intelligent terminals are more frequent. Therefore, communication security and system security issues in the intelligent platoons become hot topics. Motivated by these, the concept of zero trust was proposed.
