Latest 50 papers on transportation: Dec. 21, 2025

The world of transportation is undergoing a profound transformation, driven by relentless innovation in AI and Machine Learning. From autonomous vehicles gracefully navigating complex urban landscapes to intelligently managed smart grids powering electric vehicles, AI is at the forefront of tackling some of society’s most pressing mobility challenges. This digest dives into recent research that showcases how AI/ML is revolutionizing everything from traffic management and infrastructure security to human-robot collaboration and sustainable urban planning.

The Big Idea(s) & Core Innovations

Recent breakthroughs highlight a holistic approach to transportation challenges, emphasizing the integration of sophisticated models, robust data, and proactive security measures. A key theme is the pursuit of greater intelligence and adaptability in complex, dynamic environments. For instance, Multi-granularity Spatiotemporal Flow Patterns by Chrysanthi Kosyfaki et al. from the Hong Kong University of Science and Technology introduces an algorithm to reveal valuable insights into passenger behavior by analyzing origin-destination-time (ODT) patterns across different granularities. This is critical for transportation companies seeking flexible and useful insights into movement trends.

On the front of autonomous systems, security is paramount. John Doe and Jane Smith from the University of Technology and National Institute for Intelligent Systems in their paper, Attention in Motion: Secure Platooning via Transformer-based Misbehavior Detection, propose a transformer-based framework to detect subtle misbehaviors in dynamic vehicular networks, significantly improving the robustness of autonomous platooning communication protocols. Complementing this, Hop Le and Izzat Alsmadi from Texas A&M University-San Antonio in Intrusion Detection in Internet of Vehicles Using Machine Learning, explore machine learning for detecting DoS and spoofing attacks in the Internet of Vehicles (IoV), emphasizing the importance of data hygiene for effective detection. Further emphasizing security, Evaluating Vulnerabilities of Connected Vehicles Under Cyber Attacks by Attack-Defense Tree by Author A and Author B from University X and Institute Y offers a structured framework for identifying and mitigating security risks in connected vehicles.

Urban planning and energy management are also seeing significant AI-driven advancements. Rishit Agnihotri and Amit Chaurasia from Manipal University Jaipur introduce a scalable architecture for Electric Road Systems (ERS) in Electric Road Systems for Smart Cities: A Scalable Infrastructure Framework for Dynamic Wireless Charging, leveraging AI-based energy management for efficient power distribution. For managing real-time urban traffic, Silke K. Kaiser et al. from the Hertie School, Berlin in Spatio-Temporal Graph Neural Network for Urban Spaces: Interpolating Citywide Traffic Volume, present GNNUI, a graph neural network that interpolates citywide traffic even with sparse sensor coverage. This ties into the broader challenge of efficiently estimating traffic states from limited data, which Lindong Liu et al. from the University of Minnesota tackle in PMA-Diffusion: A Physics-guided Mask-Aware Diffusion Framework for TSE from Sparse Observations, demonstrating reliable performance with as low as 5% visibility.

Beyond direct traffic management, the implications of these systems extend to human factors and broader societal impact. Jane Hsieh et al. from Carnegie Mellon University in Beyond Riding: Passenger Engagement with Driver Labor through Gamified Interactions, explore how gamification can foster empathy and awareness of ride-hail driver labor conditions, highlighting the human element in mobility services.

Impact & The Road Ahead

The impact of this research is far-reaching, promising a future of safer, more efficient, and sustainable transportation systems. The advancements in securing autonomous vehicles, optimizing traffic flow with multi-agent reinforcement learning (as seen in Adaptive Tuning of Parameterized Traffic Controllers via Multi-Agent Reinforcement Learning and Analyzing Collision Rates in Large-Scale Mixed Traffic Control via Multi-Agent Reinforcement Learning), and understanding complex urban mobility patterns (from Potential Landscapes Reveal Spatiotemporal Structure in Urban Mobility: Hodge Decomposition and Principal Component Analysis of Tokyo Before and During COVID-19 to M-STAR: Multi-Scale Spatiotemporal Autoregression for Human Mobility Modeling) lay the groundwork for truly intelligent cities. The move towards AI-driven CAD systems for infrastructure design, as highlighted in Integration of AI-Driven CAD Systems in Designing Water and Power Transportation Infrastructure for Industrial and Remote Landscape Applications, will enable more resilient and sustainable development.

However, challenges remain. The increasing complexity of AI models demands robust testing, as discussed in Advancing Autonomous Driving System Testing: Demands, Challenges, and Future Directions, calling for V2X collaboration and the integration of Foundation Models. Ethical and legal considerations, like those explored in Criminal Liability in AI-Enabled Autonomous Vehicles: A Comparative Study, must evolve alongside technological progress to ensure responsible deployment. Moreover, balancing infrastructure expansion with potential pitfalls like Braess’ Paradoxes, as analyzed in Braess Paradoxes in Coupled Power and Transportation Systems, will be crucial. The future of transportation AI is not just about building smarter machines but also about designing systems that are safe, equitable, and harmonize with human needs and the environment. The continuous development of comprehensive datasets, efficient algorithms, and interdisciplinary collaborations will undoubtedly pave the way for a more connected and intelligent mobility ecosystem.
