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.
