摘要

In floating car data collection, the link average speed of floating cars isrnexported as link average speed of traffic flow. This results in low quality trafficrninformation being shared with the public. This paper investigates thernquantitative relationship between link average speed of floating cars and linkrnaverage speed of traffic flow considering the traffic conditions, and verifies thernresearch with simulated data based on a part road network in Changchun. Thernresults show that the link average speed of floating cars can not be used insteadrnof the link average speed of traffic flow, and that the link average speed ofrntraffic flow can be estimated accurately using the method described in thisrnpaper.
