Massive Heterogeneous Data, aka, the Big Data is being generated along with Highway daily operation, and the volume increase in fast speed. As a consequence of these massive data, data storage and analyze encoutered big challenges. How to store data in high efficency, approach of easy access and feasibility of data analyzing is an urgent issue to be addressed. This article will investigate the source of big data generated by Highway daily operation and its characteristics. Then this paper discusses the significances of big data research and data processing technologies in industry, also the challenges will be mentioned in detail.
