智能交通终端的不断发展和产生的海量交通数据给交通数据采集带来了巨大的压力。然而，现有的智能交通系统和应用大多依赖于定义良好的数据，而很少有研究关注如何从各种车载终端大量采集实时交通数据。为了解决这一问题，本文提出了一种高效、无阻塞的数据采集系统，该系统可以根据不同的优先级或QoS要求，实时地从大量的各类终端中检索流量数据，使应用层可以方便地访问其需要的某类流量数据。大量的实验和仿真结果证明了该系统的有效性、可靠性和可扩展性。此外，本文还介绍了基于该系统的两个实际应用。
The continuing development of intelligent transportation terminals and the massive generated traffic data have placed tremendous pressure on traffic data acquisition. However, most of existing intelligent transportation systems and applications rely on well-defined data, while few studies focus on how to collect live traffic data from various vehicle terminals in a large number. To solve this problem, we propose an efficient and non-blocking data acquisition system in this paper, which can retrieve traffic data based on different priority or QoS requirements from a large number of various terminals in real-time, so that the application layer can easily access certain type of traffic data it needs. Extensive experiment and simulation results prove the efficiency, reliability, and scalability of our proposed system. Besides, two real applications based on the proposed system are introduced in the paper.
