This paper presents a system architecture to promote the development of smart transportation systems. Thanks to the use of distributed ledgers and related technologies, it is possible to create, store and share data generated by users through their sensors, while moving. In particular, IOTA and IPFS are used to store and certify data (and their related metadata) coming from sensors or by the users themselves. Ethereum is exploited as the smart contract platform that coordinates the data sharing and provisioning. The necessary privacy guarantees are provided by the usage of Zero Knowledge Proof. We show some results obtained from some use case scenarios that demonstrate how such technologies can be integrated to build novel smart services and to promote social good in user mobility.

基于分布式账本的智能交通系统和社会公益基础设施

本文提出了一种系统架构，以促进智能交通系统的发展。由于使用分布式账本和相关技术，可以在移动时创建、存储和共享用户通过传感器生成的数据。特别是，IOTA 和 IPFS 用于存储和验证来自传感器或用户自己的数据（及其相关元数据）。以太坊被用作协调数据共享和供应的智能合约平台。零知识证明的使用提供了必要的隐私保证。我们展示了从一些用例场景中获得的一些结果，这些结果展示了如何集成这些技术以构建新颖的智能服务并促进用户移动性方面的社会公益。
