大数据是继云计算、物联网之后IT产业又一次颠覆性的技术变革。当前中国在大数据技术领域与世界前沿已经相对接近。面对人口高度密集、交通飞速发展、管理日趋艰难的困境,积极发展以大数据为基础的智慧交通,是时代和形势的紧迫要求。而当前中国高速推进的基础建设和国家对科技创新的大力支持,也为破解这一困境提供了良好基础。建立针对性的模型、优选科学的算法、打造云计算平台支撑,探索全新的道路交通管理技术体系,进一步减缓交通 Big data is following the cloud computing, IT industry after another subversive technological change. At present, China is relatively close to the world frontier in the field of big data technology. In the face of the population density, the rapid development of transportation and the increasingly difficult dilemma of management, the vigorous development of smart traffic based on big data is an urgent requirement of the times and the situation. At present, the rapid advance of China’s infrastructure and strong state support for scientific and technological innovation also provide a good foundation for cracking down on this predicament. Establishing targeted models, optimizing scientific algorithms, building cloud computing platform support, exploring new road traffic management technology system and further reducing traffic
