摘　　要：先进的交通管理系统和旅行者信息系统的迅速发展,引起对交通速度估计测量一种需要。然而对于铺设大量单线圈的快速路网来说,交通速度并不能直接从单线圈检测器测量出来。因此许多研究学者针对如何从单线圈的输出量估计出交通速度展开了研究。该文结合国内外的研究情况给出了算法的分类,并总结了算法存在的问题和可能开展的研究方向。Recent advanced trafficmanagement system(ATMS )and advanced traveler information system(ATIS)initiatives have created a need for a robust solution to speed estimation for a new class of applications,namely those that provide speed information to travelers.Unfortunately,vehicle speeds cannot be directly measured by single-loop detectors.So many researchers have deployed some research for speed estimation with the outputs of single-loop.In this paper,according to the research results in native and abroad,we classify the algorithms in five classes,conclude many questions existing in above algorithms and provide some possible research in the future.
