Connected vehicles today record almost every aspect of driving, from speed and braking to engine performance and travel time. This data is often promoted as the backbone of smart transportation, promising safer roads, more efficient public transport, and fairer insurance systems. Yet in practice, vehicle data is only valuable if people can trust it. Without safeguards, it risks becoming fragmented, inconsistent, or even misleading.
This issue is where Chen Shi-Huang offers a different kind of innovation. Rather than focusing on a single new technology, his research addresses a more fundamental challenge: how communities can responsibly use the vehicle data already being generated every day. His work reframes vehicle data as a “shared diary,” a collective record that only works if each entry is accurate, verifiable, and preserved with integrity.
Modern vehicles collect data through on-board diagnostic systems and vehicle-to-network communications. In theory, this information can support road safety planning, public transportation operations, fleet management, and usage-based insurance. In reality, decision-makers often face uncertainty about whether the data they see is complete or trustworthy. Professor Chen’s work explores how Internet of Vehicles systems can be combined with artificial intelligence and verification mechanisms to address this gap.
By embedding checks into the data collection and transmission process, the systems studied in this work can identify abnormal or unreliable driving records before they are stored or used. Once verified, records are preserved to prevent silent alteration, ensuring the “shared diary” remains consistent over time. This approach helps public transport operators, fleet managers, and other stakeholders rely on data without manually validating every detail.
Importantly, the work treats advanced technologies not as ends in themselves, but as tools to support social needs. Blockchain, for example, is used not for financial transactions, but as a tamper-resistant record system that strengthens trust in shared mobility data. Artificial intelligence supports pattern recognition and anomaly detection, helping users focus on meaningful insights rather than raw numbers.
Beyond research outputs, this work also contributes to education and capacity building. By translating complex vehicle networking concepts into applied courses and training programs, it helps students and practitioners gain the skills needed to work with intelligent transportation systems in real-world settings.
Together, these efforts highlight a broader view of innovation—one that values trust, understanding, and community readiness as much as technological advancement.
