In floating car data collection, the link average speed of floating cars is exported as link average speed of traffic flow. This results in low quality traffic information being shared with the public. This paper investigates the quantitative relationship between link average speed of floating cars and link average speed of traffic flow considering the traffic conditions, and verifies the research with simulated data based on a part road network in Changchun. The results show that the link average speed of floating cars can not be used instead of the link average speed of traffic flow, and that the link average speed of traffic flow can be estimated accurately using the method described in this paper.
