摘　　要：路况预警方案是解决车载自组织网络(VANET,vehicular ad-hoc network)中车辆拥堵、交通事故问题的有效手段。分析了我国目前的交通状况以及车载自组织网络的发展和应用,结合区块链技术提出了一种适用于车载自组织网络的基于区块链的路况预警方案。采用Hyperledger Fabric联盟链技术平台对该方案进行了仿真实验,实验结果表明本方案合理、可行。Road conditions early-warning scheme is effective solution to solve vehicle congestion and traffic accidents of VANET. The current traffic conditions in China as well as the development and application of VANET were analyzed. Combined with blockchain technology, a blockchain-based traffic conditions early-warning scheme for VANET was proposed. The Hyperledger Fabric alliance chain technology platform is used to simulate this scheme. The experimental results show that the scheme is reasonable and feasible.
