Special Issue Information

Dear Colleagues,

The rapid development of artificial intelligence is reshaping smart transportation by enabling both predictive maintenance and autonomous control in a unified framework. Predictive maintenance techniques, driven by prognostics and health management (PHM), allow for the real-time monitoring of critical assets such as batteries, drivetrains, and infrastructure, providing accurate remaining useful life estimation and anomaly detection. These methods improve system reliability, reduce downtime, and lower operational costs. At the same time, autonomous driving and control systems leverage trajectory prediction and motion planning to achieve safe, efficient, and human-like driving behaviors. With the support of cooperative perception and vehicle-to-everything (V2X) communication, vehicles can share intent, extend their sensing range, and operate collaboratively within dynamic traffic environments.

Recent progress in edge AI and embedded machine learning makes it possible to deploy intelligent decision-making directly in vehicles and roadside units, ensuring low-latency responses while maintaining scalability. Reinforcement learning and digital twin technologies further contribute to network-level traffic management, energy optimization, and adaptive control strategies. Safety verification and validation remain a crucial research frontier, addressing the need for assessments of the uncertainty, robustness, and trustworthiness of AI-powered systems. In addition, federated learning and privacy-preserving approaches are essential to balance data utility with security and compliance requirements.

By bringing together predictive maintenance and autonomous control, this Special Issue aims to provide a platform for innovative solutions that ensure reliability, safety, and scalability of next-generation transportation systems.

With the accelerating commercialization of autonomous driving technology, robotaxis have emerged as a significant force in reshaping urban transportation systems. However, their service efficiency and system resilience depend heavily on the spatial layout and network structure of pick-up points. Utilizing the Waymo Open Motion Dataset comprising 2,316,135 motion trajectories, this study proposes a multi-stage analytical framework to systematically identify autonomous vehicle pick-up points and evaluate the vulnerability of the constructed network. First, trajectories are stratified using kinematic criteria, and K-Means clustering is applied to 12 kinematic and geometric features to distinguish genuine pick-up and drop-off (PUDO) events from traffic-related stops. The identified pick-up points are then aggregated into spatial grid nodes to construct an undirected, unweighted network. Finally, network vulnerability is assessed by simulating random failures and three types of targeted attacks. The findings reveal that: (1) identifies 21,503 candidate pick-up points exhibiting pronounced curbside-departure characteristics from 111,321 stop-to-go trajectories. (2) The network exhibits global sparsity and high local clustering; the largest connected component (LCC) encompasses 66.1% of nodes, forming a primary service area covering the urban core, while the remaining 33.9% are scattered across 377 isolated fragments. (3) The network demonstrates strong robustness against random failures but is highly vulnerable to targeted attacks on high-betweenness centrality nodes. Removing merely the top 5% of such nodes reduces the LCC to 36.7%, and at 20% removal the LCC drops to 3.5% with near-complete loss of global efficiency. This study contributes a reproducible, machine learning-based methodology for extracting pick-up points from trajectory data and reveals structural vulnerabilities in autonomous driving service networks from a complex network perspective, providing quantitative evidence for enhancing the resilience of future urban intelligent transportation systems.
