摘要

In the era of modern societies and smart cities, intelligent transport systems (ITS) are becoming increasingly complex and interconnected. ITS incorporate sensing, control, analysis, and communication technologies to enhance transportation efficiency, comfort, and safety. Nevertheless, these systems are susceptible to a wide range of malicious attacks that pose a serious threat to the availability, security, and integrity of data interchange, leading to accidents, traffic jams, and monetary losses. Traditional centralized security solutions are often inadequate to address these threats. Thus, blockchain technology, with its decentralized, transparent, and immutable nature, offers a promising alternative for improving security in ITS. This paper explores the potential of Ethereum blockchain-based smart contracts to improve security in ITS. The proposed system is built to manage large numbers of concurrent transactions and uses distributed consensus mechanisms to maintain high throughput and evaluate latency under real-time operational demands. Through representative ITS scenarios, we provide both qualitative and quantitative assessments highlighting the framework’s capabilities to enhance security, system resilience, and computing scalability.
