摘　　要：在综合国内外文献的基础上,阐述了浮动车技术进展和应用现状。分析了浮动车轨迹的配准技术,分析表明综合考虑道路几何约束和车辆状态行驶规律的配准算法具有较高得匹配效果。简述了基于FCD计算路段平均速度,行程时间的算法,分析各种算法的适用场景和优缺点。最后分析总结了FCD更新和获取电子地图的方法,指出这是一种成本较低效率较高的可行的方法。On the basis of synthesizing the literatures at home and abroad,the development and application status of floating car technology are elaborated. The trace registering technology of the floating car is analyzed. The analysis result shows that the registering algorithm synthetically considering the road geometric constraint and vehicle driving rules has high marching effect. The algorithm based on FCD（floating car data）to calculate the average speed of road section and travel time is described briefly. The applicable situation and merits of various algorithms are analyzed. The methods of FCD update and electronic map acquisition are analyzed and summarized. The analysis data shows that the proposed method is a feasible method with low cost and low efficiency.
