Abstract
Smart cities provide citizens with smart and advanced services to improve their quality of life. However, it has been observed that the collection, storage, processing, and analysis of heterogeneous data that are usually borne by citizens will bear certain difficulties. The development of the Internet of Things, cloud computing, social media, and other Industry 4.0 influencers pushed technology into a smart society’s framework, bringing potential vulnerabilities to sensor data, services, and smart city applications. These vulnerabilities lead to data security problems. We propose a decentralized data management system for smart and secure transportation that uses blockchain and the Internet of Things in a sustainable smart city environment to solve the data vulnerability problem. A smart transportation mobility system demands creating an interconnected transit system to ensure flexibility and efficiency. This article introduces prior knowledge and then provides a Hyperledger Fabric-based data architecture that supports a secure, trusted, smart transportation system. The simulation results show the balance between the blockchain mining time and the number of blocks created. We also use the average transaction delay evaluation model to evaluate the model and to test the proposed system’s performance. The system will address residents’ and authorities’ security challenges of the transportation system in smart, sustainable cities and lead to better governance.
Highlights
In recent decades, rapid urbanization has been affected by urban relocation due to better employment chances and access to a better education system
We have proposed using private blockchain to address data security and transparency issues in smart cities’ transportation systems. e novelty of this work is to design a decentralized platform for combining IoT and blockchain technology with smart transportation systems. is system will help enhance the legacy transportation systems by overcoming data security issues, transparency, and trust
Smart cities provide citizens with smart and sophisticated services that can improve their quality of life
Summary
Rapid urbanization has been affected by urban relocation due to better employment chances and access to a better education system. It has distributed ledger technology that provides a reliable way to perform transactions without a third-party involvement Blockchain features such as immutability, verifiability, transparency, integrity, and security are required elements for developing a smart transportation system [28]. It is very beneficial for various ITS applications like accident detection, criminal activity detection, user profiling, and reporting, controlling, and monitoring traffic Another similar kind of work, blockchain-based ITS, is proposed to solve the data security and privacy issues and boost the vehicles to share their data with ITS systems [35]. We have designed an IoT- and blockchain-based architecture for data security and transparency in smart transportation systems. It provides various services such as navigation, bus priority signals, toll collection, traffic congestion estimation, and gas station location
